Does GLONASS work now: diagnosis and solutions

The question of whether the system is functioning GLONASS At the moment, not only motorists are concerned, but also owners of commercial vehicles, logistics companies and even ordinary smartphone users. With sanctions pressure and frequent reports of disruptions, many are wondering whether it is possible to rely on domestic navigation or whether it is worth switching to American GPS immediately. The answer to this question is not a simple yes or no, as the situation depends on a variety of technical and geographical factors.

On the one hand, the positioning system is a strategically important object and is under the constant care of the state, which guarantees its basic performance. On the other hand, users often face problems when connecting telematics devices, failures in the display of tracks or refusal to register EPPs. To understand whether the problem lies in a global failure or in your particular equipment, you need to conduct a deep diagnosis.

In this article, we will discuss in detail the current state of the orbital constellation, methods of signal verification on various devices and the legal nuances of using navigation. You will learn why the tracker can be silent, how to distinguish a software failure from a physical antenna failure, and what steps to take if the system stops transmitting data at the right time.

Current status of orbital constellation

Orbital grouping of the system GLONASS Today it is in a stable condition, providing coverage of the territory of the Russian Federation and adjacent regions. According to Roscosmos, the number of active satellites in orbit regularly varies between 23 and 24 units, which is sufficient for a confident positioning anywhere in the country. However, it is worth considering that satellites are complex technical devices with a limited service life, requiring regular replacement.

Unlike its competitors, the Russian system uses not only medium-Earth orbits, but also satellites in highly elliptical orbits, which is especially important for northern latitudes. That is why in the Arctic zones and hard-to-reach regions of Siberia GLONASS Often shows better results than foreign counterparts. However, routine maintenance or the withdrawal of older vehicles may temporarily reduce accuracy in individual locations.

It is important to understand that even with the full serviceability of the space segment, ground adjustment stations can experience loads. This does not mean that the system is not working, but the positioning error may increase temporarily. For civilian users, this can be expressed in the “jump” point on the map or increase the time of cold start of the navigator.

⚠️ If your navigator or tracker shows no satellites in an open field in clear skies, the problem is 95% of the time local equipment, not space. The global failure of the entire system is an extraordinary event and is immediately covered by official sources.

For those who want to know the technical status of the group in real time, there are specialized monitoring resources. They map the telemetry of each satellite, allowing you to estimate how many satellites are in sight right now.

How to check the work of GLONASS on a smartphone

The easiest way to check if the system is working on your mobile device is to use specialized diagnostic applications. Modern smartphones tend to support multiple satellite systems at the same time, but not all users know how to (check) the status of each. First, you need to download the application, for example, GPS Test, GPS Status & Toolbox Or similar.

After you start the program, you need to go out into the open space. Inside buildings, especially in basements or metal framed rooms, satellite signals can be completely blocked. If the app shows that satellites are found (usually designated by country flags or abbreviations RUS for GLONASS and USA for GPS), but there is no fixation of coordinates, it may be a problem in the Internet or time settings.

Pay attention to the signal indicators. Green color of the column means confident reception, yellow - uncertain, and gray - lack of signal. If you see GLONASS satellites (RUS) but they are gray, try turning on the “Use satellites for geolocation” mode in your phone settings and wait a few minutes to warm up the antenna.

• 📱 Settings check: Make sure that the location section selects either GPS or High Accuracy mode.
• 📡 Visibility analysis: At least 4 GLONASS satellites must be visible in the application for primary positioning.
• ⏱ Start time: A cold start (the first start after a long downtime) can take up to 15 minutes, a hot start can take several seconds.
• 🔋 Energy conservation: Check if the power saving mode turns off the navigation module in the background.

If after all the manipulations, the smartphone has not “seen” Russian satellites, although the American catches, perhaps your device has an old-style navigation module or with limited frequency support. In this case, using an external Bluetooth receiver can be the solution.

Diagnostics of automotive trackers and terminals

Owners of transport equipped with satellite monitoring systems, it is important to distinguish between problems with the GSM channel and problems with satellite reception. If the controller does not see the car on the map, it does not mean that GLONASS It's not working. Often, the tracker simply cannot transfer the accumulated coordinates to the server due to the lack of cellular coverage.

For diagnosis, it is necessary to check the indicators on the terminal body. Usually, the green flashing indicator is responsible for the GSM, and the blue or red indicator is responsible for the satellite module. If the GLONASS indicator burns constantly or does not burn at all, this may indicate a break in the antenna or its closure. The antenna should be installed horizontally, with a metal side upwards, in the line of sight of the sky.

Particular attention should be paid to the settings of the SIM card. If the balance runs out of money or the card is blocked, the tracker can continue to write data to internal memory, but not transfer it. In this case, when the connection appears, the device will try to unload the archive, and the tracks will appear on the map with a delay.

In some cases, you need to reset the settings or flash the device. Manufacturers regularly release updates that improve satellite search algorithms in challenging environments. If you use budget Chinese trackers, make sure they support modern L1 and L2 frequencies, as older models may lose signal when upgrading to grouping.

Problems with EPTS and registration of transport

A separate and very painful topic is the work of the system in the design Electronic Passport of Transport Vehicle (EPTS). Many owners are faced with a situation when when trying to enter data into the system of EPA (Electronic Passport System) comes a refusal or status "Expected confirmation" due to the allegedly missing data on the utilization fee or status of GLONASS.

Technically, the EPP system is integrated with customs and manufacturer databases, but human error and operator errors often create the illusion of inoperability. If the system says that “the data on GLONASS is not found”, it may mean that a specific tracker installed on the car, has not passed certification or is not included in the register of approved devices at the time of inspection.

There are also cases when the servers of the operator EPTS carry out scheduled technical work. During such periods, the system may not be available to all users or may operate with restrictions. This doesn’t mean that navigation isn’t working, it’s just that the data sharing service is temporarily suspended.

Status in the system	Probable cause	Action by the owner
No signal.	Antenna in a "jamming" or damaged	Check the antenna installation
Data not transferred	Lack of GSM signal	Get out of the no-communication zone
Certification error	Tracker not in the register of the Ministry of transport	Replace the device or obtain a certificate
Server unavailable	Operator-side technical work	Try again in 2-3 hours

To solve legal issues related to EPP, it is often required to provide screenshots from the personal account of the monitoring system, confirming that the device is working and transmits coordinates. It is important to have access to your operator’s monitoring platform.

⚠️ Warning: Never try to use GLONASS emulators or software tricks to pass a checkup or registration. Modern diagnostic systems easily detect the substitution of coordinates, which threatens the cancellation of the EPPTS and fines.

The impact of weather and terrain

Radio signal used by the system GLONASSHe has a certain penetrating ability, but he is not omnipotent. Dense cloudiness, heavy rain or snowfall can weaken the signal, although they do not block it completely. However, there are factors that are guaranteed to disrupt navigation.

The main enemy of the satellite signal is metal and concrete. Being in a tunnel, underground parking, surrounded by high-rise buildings ("city canyons") or in a dense forest leads to a loss of signal. Under such conditions, the receiver enters Dead Reckoning mode using gyroscopes and accelerometers, but accuracy drops sharply.

Interestingly, magnetic storms and solar activity also affect the operation of the satellite constellation. During periods of high solar activity, short-term disruptions and increased positioning error across the planet are possible. It is a natural factor that cannot be technically influenced.

Effect of toning on signal

Metallic tinting of the car’s glass can shield the satellite signal if the antenna is installed inside the cabin. If you have a tight tinting, it is recommended to take the antenna to the roof or use external magnetic antennas.

In winter, when trees are devoid of foliage, the signal is received better than in summer in a dense forest. However, icing the antenna itself (if it is external) can also reduce the quality of reception. Regular cleaning of the antenna surface from snow and ice is a simple but effective measure.

What is GLONASS different from GPS and what is better

The question of “what is better” is often incorrect, since modern receivers are multisystem. They are also receiving signals from the US. GPSand from Russian GLONASSand often from the European Galileo Chinese BeiDou. Combining signals from different systems allows to increase the accuracy and speed of coordinate determination.

The main architectural difference between GLONASS is the use of frequency channel separation (FDMA), while GPS uses code (CDMA). This makes GLONASS more resistant to narrowband interference, but requires more complex and energy-intensive reception equipment. But in high latitudes, where GPS satellites can be low above the horizon, GLONASS satellites hang almost overhead.

For the average user, the difference is not noticeable if he is not in specific conditions (mountains, north, dense buildings). In such cases, the presence of GLONASS support in the device becomes a critical advantage, providing navigation where GPS is “blind”.

• 🌍 Geography: GLONASS is sharpened under the Russian Federation and the Northern Hemisphere, GPS is a global system.
• 📡 Accuracy: In the middle latitudes of Russia, GLONASS often gives a smaller error.
• 🛡 Independence: The use of the domestic system guarantees the operation of navigation in any geopolitical scenario.
• ⚡ Speed: Combined mode (GPS+GLONASS) gives the fastest location determination.

So, to abandon GLONASS in favor of GPS does not make sense. The optimal strategy is to use devices that support all available positioning systems. This ensures maximum reliability and fault tolerance of navigation in all conditions.

Questions and Answers (FAQ)

Why doesn’t GLONASS work on the phone, even though it used to work?

There may be several reasons: the date and time settings are lost, the flight mode is turned on, the antenna is damaged after the fall or update of the operating system. Try resetting your network settings or performing a full A-GPS data reset in a dedicated application.

Is it necessary to have GLONASS for a passenger car?

For personal use, no. However, for commercial vehicles carrying dangerous goods or vehicles participating in the Platon system, the presence of a certified GLONASS terminal is a mandatory requirement of the legislation of the Russian Federation.

Can I turn off GLONASS programmatically?

In most smartphones, you can choose a priority system or mode of operation in the engineering menu, but completely disable the module without root rights is difficult. In car trackers, shutdowns often require physical intervention or special SMS commands if designed.

Does a magnetic storm affect the navigation?

Yes, strong geomagnetic disturbances can cause short-term disruptions in satellite signal transmission, increasing the positioning error. Usually these last from a few minutes to several hours.

What if the EPP is not issued due to GLONASS?

It is necessary to request from the telematics operator a certificate of serviceability of the device and data transmission. If the problem is on the database side, you should contact the technical support of the EPPS system or the accredited operator through which the application is submitted.
