Suppose you have a garden in the country. It grows apples. And you have a neighbor who also has apple trees in his orchard. However, the neighbor is very old and does not care for the garden. You, out of friendship, ask him for permission to take care of his garden, and take the harvest for yourself. The neighbor agreed. As a result, you have your main garden, and there is an additional one. And the whole harvest goes to you.

This is how satellites work. These are additional sites that still drive traffic to your main resource.

Types of satellite sites

In the modern understanding of SEO, there are 3 types of such sites:

Static - as a rule, they are created on a simple html code, the content on them is not updated.
Dynamic - created on the basis of popular CMS, differ little from regular sites and often have a constantly updated news feed.
Doorways are a special type of satellites, the purpose of which is to redirect a visitor from search engines to a specific resource.

Why create satellites

Among the main areas of application, there are three main niches in which the creation of satellites is widely used.

Sales increase

Satellites are created for the main Internet site or store, while the topic for each satellite is chosen as narrowly focused as possible. For example, if traffic from search engines is required for the sale of boats and fishing gear, thematic sites are created on different domain names: lure fishing, boats, outboard motors, etc.

The narrower the subject of the satellite, the faster it will attract an interested audience. The user will visit such a site. Read the information. Its material will be of high quality, then the person will be interested in the main site. And, perhaps, will make a purchase on it.

Bringing targeted traffic

For various purposes, targeted traffic from search engines may be required. For this, satellite sites are created for given key phrases and promoted in search engines until the desired effect is obtained.

Filling a niche in the issue

In order to oust competitors from the first positions, entire networks of satellite sites are created, which fill the entire top of the issue for certain key queries.

Benefits of website promotion by satellites

Benefits from promotion by satellites are mainly large and medium-sized commercial projects. This promotion technique allows you to get a sufficiently high-quality and constant flow of traffic from search engines.

The ability to promote not one, but several projects with the help of one high-quality network of satellites.
After creating, setting up and initially purchasing links, there is no need for relatively high promotion costs.
It is possible to cover part of the maintenance costs by placing contextual advertising. It should be borne in mind that advertising will select a part of potential customers.
A quality link mass will constantly support the main projects for the necessary key queries.
There is no need to spend money on buying links for promoted sites; as a result, the webmaster is less dependent on price changes in the niche and market conditions.
Among other things, this is a good way to force competitors out of the market for the required key queries, with a certain one.

Disadvantages of satellite promotion

High investment at the start of the project. Each satellite site requires a separate domain name and hosting. In addition, it will require filling it with high-quality content and developing an individual design.

After creating a site / satellite sites (since quite often it is created not one, but a dozen or more), it will take time for promotion, search engine optimization and link building, which will also require additional costs for the purchase.

Creating satellite sites is a way of promotion, designed for a considerable budget, and pays off in the long run.

This method of promotion is not suitable for small projects, since for the same money it would be better to organize an advertising campaign in contextual advertising networks. It will give an instant rise in visitor requests.

What should be the satellite resource

Unique content - high-quality texts and graphic materials for sites, are considered by search robots more loyally. At the same time, there is a higher probability of the pages of such a satellite being quickly included in the search results. With non-unique content, there will be practically no chance to break into the top of the issue, and the probability of applying a filter to the site is quite high, as this will cause the site to be pessimized.
Thematics - the topics of the promoted resources should correspond as much as possible to the topics of the satellite. This will increase the relevance of search results. Matching topics will be more loyally perceived by search engines.
Unique design - not a template design will be an additional factor that positively affects the perception of the site by search robots as a unique Internet resource.
– sites of the same network can be created on various platforms, ranging from SaaS platforms to popular CMS, but it should be borne in mind that a large network will require a single admin panel that allows you to easily manage all settings and content. Since the management of each network project separately will take a lot of time. To do this, you should enlist the services of a specialized programmer. On the Internet you can find examples of satellite sites, executed on completely different platforms.

Since this process takes a lot of resources, both material and temporary, promotion in this way is most appropriate if there is a team of specialists. In this case, you can relatively quickly create a network of sites on relevant topics and fill it with high-quality content, fitting it to the requirements of the main PS.

For one person running his own portal, this will be a rather difficult task that takes a lot of time, money and effort. In addition, if the grid is made poorly, you will not be bypassed by search engine filters. In any case, it's up to you.

This is perhaps one of the most controversial glucometers. Someone uses and is satisfied, others assure that the device gives a large error. We believe that everything is relative. Since we are talking about glucometers of this line, it means that it is popular and there are people for whom the device is perfect. Let's take a look at the device in detail.

The Satellite line is glucometers of the Russian manufacturer ELTA. The line includes 3 models: Satellite, Satellite Plus and Satellite Express.

Each model has its own differences. But in general, the latter is the newest device. We will analyze it.
For you to understand, the Satellite and Satellite Plus models are like outdated prototypes of the Satellite Express. The first model is like Blitz from Zootopia. The measurement time is already 40 seconds, for Satellite Plus it is already 20 seconds. For those who are not in a hurry, but want to save money, it may well be suitable.
But let's take a look at the most updated model.

Satellite Express looks like a pretty good glucometer. The sampling time is 7 seconds. The measurement range is wide 0.6-35 mmol / l. During testing, the error is within the normal range.

In terms of the volume of a drop of blood for measurement, he is a bit bloodthirsty - 1 μl. But with test strips it’s already joyful - they are self-priming.

Memory is not very large - 60 last measurements. But there is a double-edged sword here. By purchasing glucometers with more memory, you will pay much more. So it's up to you to choose: budget vs memory. You can not be too lazy and keep a diary of self-control in order to save money.

The device is calibrated by capillary blood. This is good, given that you do not need to carry out additional calculations, reducing the figure by 11%.

In terms of device design, it is a good choice for people with low vision. The large display and large font is a great solution.

The test strips are packaged individually. It's comfortable. because problems with improper storage disappear. It is also good if you do not often have to take measurements. The test strips will keep for a long time.

The cost of a glucometer and test strips is very pleasing. Still, this is one of the most budget options.

How painlessly the piercer of this company works must be judged individually. Reviews are very varied.

In general, the Satellite Express meter is a good choice. The device has many benefits for people with type 2 diabetes. Large screen, good accuracy, individual packaging of test strips and low cost play in favor of the device.

How do you rate this glucometer? We will be grateful for your feedback.

Since 1993, the Russian plant ELTA, which specializes in medical equipment, has launched the production of a line of satellite glucometers. The first models, as often happens, were imperfect, but each subsequent modification brought the device closer to international standards. The most demanded analyzer in this series is Satellite Express. The reliability and affordability of the device allows it to compete with many branded counterparts. In particular, like Western glucometers, Satellite Express has a lifetime warranty.

Varieties and equipment

All Satellites use an electrochemical technique to process the result. The test strips are developed using the “dry chemistry” method. Calibration of the device is provided by capillary blood, test strips are entered manually.

There are three models of bioanalyzers in the line of Satellites: ELTA Satellite, Satellite Express and Satellite Plus.

In the kit of any glucometer you can find:

Instrument with CR2032 battery;
piercer;
fabric packaging;
control strip;
25 test strips with lancets;
Recommendations for use with warranty documents.

In the latest model of the Satellites, you can see a fabric case with a zipper, the previous versions were produced in a plastic container. There are many complaints about the old packaging for the Satellite glucometer in the reviews on the forums: the plastic is short-lived - it cracks, breaks into two halves, which have to be glued together with adhesive tape. The first of the Satellite models is equipped with ten strips, the rest already contain 25 pieces.

Characteristics of bioanalyzers

Characteristics of glucometer models can be presented in the table. The leader in the list is the Satellite Express analyzer, and not only due to the cost: you definitely won’t have time to pour a cup of tea while it analyzes the sample.

Options
Measurement limits	from 0.6 to 35.0 mmol/l	from 1.8 to 35.0 mmol/l	from 0.6 to 35.0 mmol/l
Time of processing	7 seconds	40 seconds	20 seconds
Amount of blood	1 µl	4-5 µl	4-5 µl
Memory	60 measurements	40 measurements	60 measurements
Device cost	1300 rub.	870 rub.	920 rub.
Price of test strips (for 50 pieces)	390 rub.	430 rub.	430 rub.
Price of lancets (for 50 pieces)	170 rub.	170 rub.	170 rub.

Advantages and disadvantages of bioanalyzers

All devices are sufficiently accurate, with a concentration of sugars in the bloodstream in the range of 4.2-3.5 mmol / l, deviations from laboratory indicators are no more than 20%. Judging by the feedback from users and experts on thematic forums, Satellites are not without other advantages:

Lifetime warranty for the entire line of ELTA bioanalyzers;
The budget cost of devices, including consumables;
Ease of operation (only 2 buttons, the whole process is intuitive);
Minimum result processing time (in Satellite Express);
Display with large numbers;
The power of one battery is enough for 5 thousand measurements.

It is important to observe the storage conditions of the device: it does not like moisture and aggressive ultraviolet radiation. The temperature range is impressive: from -20°C to +30°C, but for research you need heat within +15-30 degrees with 85% humidity.

The most frequently indicated shortcomings are:

Insufficient measurement accuracy (especially in the middle and severe stages of diabetes mellitus);
Modest (compared to Western counterparts) amount of memory;
Solid dimensions for a portable device;
There is no way to connect to a PC.

The manufacturer's instruction claims that the measurement accuracy is within the standards for the household category of analyzers (up to 20%), but in comparison with branded glucometers, the error is significant.

Application guide

After getting acquainted with the complete set of the Satellite Express glucometer, you need to study the instructions for use from the manufacturer to make sure that the device is working (preferably at the stage of its purchase). A control strip is inserted into the switched off device (there is a special slot for this). With normal settings, a smiling smiley face and indicators of 4.2 - 4.6 appear on the display. Now this strip can be removed.

The next step is coding the device:

A special strip for coding must be placed in the connector of a non-working device.
The screen should display a three-digit code corresponding to the test strip lot number.
Now you can remove the strip from the meter.
Wash hands in warm soapy water and dry thoroughly.
Install the scarifier in the piercer.
The test strip is inserted into the device with contacts to the device, first you need to compare the code on the jar with consumables and the display again.
After the flashing drop symbol appears, you can extract blood from the pad of your finger and bring it to the edge of the test strip. You can speed up the process with a light massage - intense pressure distorts the results, since intercellular fluid is mixed with the blood.
For maximum accuracy, it is better to use a second drop for this purpose, and carefully remove the first with a clean cotton pad.
After 7 (20-40) seconds (the exact time is indicated in the device manual), you can see the measurement result on the screen.
Do not rely on memory - write down the readings in your observation diary.

Expendable materials

An important advantage of all satellite glucometers is the availability of consumables. The manufacturer produces them in sufficient quantities and sells them in all retail outlets at a cost acceptable to any category of consumers. Another pleasant moment is the personal packaging of the strips, which increases the warranty period of the open case. Each type of analyzer produces its own strips:

For analyzer Satellite Express - PKG-03;
For the Satellite Plus device - PKG-02;
For the device ELTA Satellite - PKG-01.

Before purchasing, check the warranty period of consumables. The lancing device is compatible with all types of universal lancets as long as they have a square base:

Taiwanese Tai doc;
Polish Diacont;
German Microlet;
South Korean LANZO;
American One Touch.

Lancets of these brands are not difficult to find in the retail network without prescriptions.

Price

The cost of the device is of decisive importance: you can enumerate the numerous advantages of foreign analogues, but if you can afford only a budget option, then the choice is obvious. By the way, the price for the Satellite Express glucometer is 1300 rubles, but it quickly pays for itself due to test strips. For 50 pieces, you need to pay only 390 rubles (for comparison: the same package of strips for the One Touch Ultra Easy glucometer will cost 800 rubles).

Other models of this brand are even cheaper: an ELTA Satellite or Satellite Plus glucometer can be bought for 1000 rubles, but the strips for them will come out more expensive - 430 rubles / 50 pcs.

In addition to the strips, you also need disposable lancets for the piercing pen, but they are cheaper: 170 rubles / 50 pcs.

It turns out that if the device itself is reliable and durable, its maintenance favorably distinguishes the Satellite line of glucometers from foreign analogues. In the end, not everyone is chasing new things and not all pensioners need a connection to a PC, voice functions, meal notes, a bolus counter, a built-in lancing device. Young people might not like this design and functionality, but perhaps the manufacturer was targeting a different target group of buyers.

If we talk about automotive gearboxes, then the most common option has always been considered the mechanical appearance of this device, and the automatic gearbox was associated more with a female driver. However, in recent years, automatic transmission is gaining more and more popularity not only among women, but also among males.

Naturally, each of the species has its own advantages and disadvantages, so it is certainly impossible to evaluate them as unconditionally good or undeniably bad. In this article, we will try to understand a little about the operation of an automatic transmission, paying special attention to some of its components, or rather, the so-called gearbox satellites.

What are transmission satellites?

In automotive practice, the concept of "satellite" means one of the elements, also called a planetary gear. From a constructive point of view, this is a planetary gear equipped with a movable axis of rotation. As a rule, this part is located at the junction with the sun gear. The sun gear is the central element around which the gears rotate. Thanks to this design, the principle of operation of the satellite resembles our solar system, around which the planets revolve, hence the name of the transmission - planetary.

The planetary gear is the most important part of the gearbox, because it is she who provides the entire range of working relationships of the automatic transmission, and the rest of the devices only help its high-quality functioning.

In our time, this type has become widespread not only in the automotive world, but also in everyday human life. For example, the planetary gear is the basis of many electric screwdrivers.

In an automatic car box, as a rule, there are two such gears that are combined into one component. This includes the sun gear (located in the center), carrier and ring gear. Each component can play the role of an input or output gear, or even be blocked. The gear ratio is determined by the function selection of each component. Such a system is present on many automatic transmissions and is considered the most durable, since due to the slight activity of the teeth, they rarely fail. In addition, the planetary gear is simple and compact, which allows for smoother gear changes, avoiding gaps in the power transmission of the vehicle's power unit.

Replacing the transmission pinion

When cracks appear on the differential gears (including the satellites) or the teeth begin to crumble, this is a sure sign that the specified element must be replaced. In case of minor damage to the sliding surfaces, the existing defect can be eliminated by grinding with fine-grained sandpaper, followed by polishing.

When replacing the gearbox satellite, a series of sequential steps must be performed. First, unscrew the bolts securing the driven gear of the final drive, with which it is attached to the differential box. The relative position of the box and gear should be noted. Then, install some kind of stop under the gear and press the differential box out of it.

A hammer and a soft metal drift through which blows will be applied will help to complete this task. Further, using a beard, they knock out the fixing pin of the axis of the satellites and take it out of the box. Now, when it is in your hands, you can easily remove the axis of the satellites, and after it, turning the gears of the differential, remove the satellites themselves from the box, along with side gears and support washers. Inspect the working surfaces of the details of the teeth of the satellites, splines and teeth of the side gears. If the theory about the strong wear of their working surfaces was confirmed and you noticed that the teeth really began to crumble, then it is better not to postpone the replacement procedure.

At this stage, all that is needed is to replace the failed parts, new elements and assemble everything in reverse order.

The principle of operation of the satellites in the gearbox

To understand the principle of operation of the gearbox satellites, we will consider it in more detail. The functioning of the automatic transmission is ensured by the work of two main components - fluid coupling and already mentioned planetary gear. The fluid coupling is presented in the form of two paddle wheels, which are placed in a single housing filled with special oil. One of the wheels - pumping, connected to the crankshaft of the engine, and the second - turbine, directly interacts with the transmission.

When the impeller begins to rotate, the oil flows that are expelled help spin the turbine wheel, allowing a 1:1 ratio of torque to be transmitted. In the case of a car, this option is completely unsuitable, because here it is necessary that the torque could change over a wide range.

Therefore, taking into account this fact, an additional wheel was installed between the pump and turbine wheels - a reactor wheel, capable of adapting to the operating modes of the machine, which is expressed either in its rotation or in immobility. In a stationary state, the reactor increases the flow rate of the working fluid that circulates between the wheels, and the higher the speed of its movement, the greater the impact on the turbine wheel.

Thus, on the turbine wheel increases, that is, we influence its transformation. Due to this, a device with three wheels can no longer be called a hydraulic clutch, but a torque converter.

However, he is not able to completely transform the rotation speed within the required limits. In addition, to ensure the movement of the car in reverse, it is also beyond its power. That is why, such a device is supplemented with a set of separate planetary gears with different gear ratios. From the outside, it may look as if several single-stage gearboxes were placed in one common housing.

planetary gear- This is a mechanical system that consists of several gears - satellites, rotating around the central gear. All together, the pinion gears are fixed by the planet carrier, and the outer ring gear is internally meshed with the planetary gears. The satellites fixed on the carrier rotate around the central gear, and the outer gear moves around the satellites. The difference in gear ratios is achieved by fixing different parts relative to each other.

The control system is responsible for shifting gears, which was originally completely hydraulic, but in the modern world, electronics came to the rescue.

But why, in an automatic transmission, is it the planetary gear that is most often used? Can you try using shafts with gears attached to them (as in a mechanical box)? The fact is that the described type of transmission is more compact and provides fast, and most importantly smooth speed switching, without a break in the power transmission of the motor. Moreover, due to the transfer of load by several satellites, the stress of the teeth is reduced, which ensures a relatively long service life of the planetary gears.

In a single version of such a transmission, the torque is transmitted through its two elements: one of which is the leading one, and the second is the driven one. The third constituent element remains stationary.

A two-stage planetary gear consists of two combined gears. It consists of one ring gear (always out), two sun gears and two sets of planet gears. The location of the satellites in the carrier is made in such a way that one is placed below the second and does not mate with the ring gear, connecting only with another satellite, through which the specified connection is achieved. The smaller gears mate exclusively with the smaller sun gear, while the larger gears mate with the larger gear as well as the smaller pinion gears.

Advantages and disadvantages of using planetary gears in a gearbox

The use of planetary mechanisms in the gearbox has a number of advantages, among which are:

- relatively smaller dimensions of the transmission;

High reliability of work (performance is maintained even in case of loss of several teeth of the central wheels);

High efficiency with relatively large gear ratios;

Absence of transverse loads on the main shafts;

The possibility of disconnecting the shaft of the power unit from the transmission, of course, only if the clutches of the transmission box are used (in this case, the gearbox simultaneously acts as the main clutch);

Relatively high gear shift speed, which significantly increases the average pace of the vehicle.

However, along with the advantages, there are also some "cons" of using a planetary gear in a gearbox. The main ones are the need for an increased level of manufacturing accuracy, which is explained by the presence of redundant links (“extra” satellites), and a sharp decrease in efficiency when working with large gear ratios.

Often, those planetary gears, which include epicyclic gears, have a relatively higher level of efficiency than those that consist only of external gears. For this reason, in planetary gearboxes, the simplest planetary gear sets with an epicycle are used. The number of shifts in one row, as a rule, does not exceed three, which greatly simplifies the clutch and brake control system. In addition, the number of planetary gears of one gearbox also, most often, does not exceed three.

The presence of features in the design and calculation of such gears is associated with the presence of excessive kinematic links (satellites). The maximum possible number of satellites in one row is limited by the neighborhood condition, which states that their number must be such that they do not touch each other.

True, in reality, the number of satellites rarely exceeds six, which is explained by the difficulty of evenly distributing the load between them in the case of a large number of them. The second necessary condition for the existence and normal functioning of the planetary gear set is the observance of the condition of alignment, or rather the alignment of the central wheels, carrier and epicycle. In the case of a simple planetary gear set, such a condition is expressed in the equality of the interaxal distances of the engagement of the sun wheel and the satellite, as well as the engagement of the satellite and the epicycle.

The branching of the power flow during the transmission of power loads through satellites requires certain measures to be taken to ensure the uniform distribution of incoming loads between all satellites. Among the main reasons for the lack of such uniformity, the following are distinguished: inaccuracies made in the manufacture of gears; different center distance of satellites; misalignment of the geometry of the axes of the satellites (the axes of the satellites and the main transmission axis are not parallel to each other), etc.

In the absence of ensuring a uniform distribution of the load, the discrepancy in its value, for some satellites, can reach 70%. Equalization of the incoming load between all satellites can be achieved in one of the following ways:

By improving the manufacturing accuracy of planetary gear parts

By creating a floating type of carrier or one of the centrifugal wheels, so that they can have some radial mobility relative to the body and associated elements;

Through the use of elastic structural elements(for example, through the use of an epicycle rim with increased flexibility and satellite axles with low rigidity).

The calculation of the strength of the described type of gears is carried out according to the formulas used in working with cylindrical gears. When determining the calculated moment that acts in the gearing, the number of satellites responsible for the transfer of workloads, as well as the uneven load on their teeth, are taken into account.

In the manufacture of elements of planetary gears, the same materials are used as in the creation of conventional gears. Often, these are engineering and alloy steels of carbon origin, which are additionally subjected to improved heat treatment.
