The Russian Aerospace Forces (VKS) are using American-made GPS systems during their combat missions in Syria.

The revelation was made by Russian politician Soviet Air Force veteran Colonel Viktor Alksnis, on his Facebook page.

He drew attention to recently-released photographs of the cockpit of a Su-34 Fullback fighter-bomber in Syria. This is also the case of the Su-25SM3 fighter jets.

Experts later confirmed that the photo shows a U.S.-manufactured GPS receiver developed by the Garmin company. Russian military pilots used the GPS receiver of Garmin’s popular entry-level eTrex Legend family.

It is more than likely that the Russians installed them in their planes in case their navigation systems did not work.

Garmin says that with its high-sensitivity, WAAS-enabled GPS receiver, eTrex Legend locates position quickly and precisely and maintains its GPS location even in heavy cover and deep canyons.

This etrex series of GPS handhelds should be familiar to the many tourists who usually buy one of these to use in their travels.

In the photographs, the left side of the HUD of Su-25SM3 is equipped with a Garmin GPSMAP 496 aviation GPS navigation terminal.

This navigation system is a civilian navigation machine familiar to aviation enthusiasts. In addition to positioning navigation, it also provides weather and terrain warning service, because there is a European database, it is very suitable for use in Europe and the nearby regions.

The image was allegedly taken in 2016 over Raqqa at the time of the KAB-500Kr guided bombs being dropped over the Euphrates, in the cockpit of a Russian warplane recorded the use of the American GPS navigation system simultaneously with Russian equipment.

In this case, American pilots do the same. Where there is a likelihood of falling under the operation of the electronic warfare systems of the “probable partners”, they use the navigation systems of Russia and China as insurance.

Both the Su-34 and Su-25SM3 actually have their own satellite navigation system, especially the Su-25SM3 is a new model that has only been upgraded in recent years. One of the key points of its upgrade is to improve the satellite navigation capabilities.

The original Su-25SM was equipped with A-737-01 GPS and GLONASS dual-signal satellite navigation receiver when it was upgraded, while the new Su-25SM3 is to further improve the satellite navigation receiver to PPA-S /V-06, also compatible with GPS and GLONASS dual signals, and also adds the ability to edit waypoints.

It stands to reason that since the built-in navigation is compatible with GPS signals, even if the Russian GLONASS is not strong, there is no need to worry about the lack of navigation signals, because there can be GPS installed on the warplane, making it pointless to buy a civilian one. Still, it is plain to see that the GPS portable terminal is installed on the plane.

This situation can only mean that the navigation systems of these two fighters cannot satisfy the Russian pilots, or that they cannot meet the requirements of the Russian military. It may be that there is a problem with the reliability of the hardware, or it may be that the data information of the electronic map is not perfect.

It’s pretty smart to do it. The US would attack the Russian version but would not take out their own and this way the Russian aircraft still get the job done!


Whazup sprogbreath,soros booted out for good eh feminazi tranny loving sic gimp:Fekn liar:


Redundancy is an integral part of engineering – and taken very seriously in aviation engineering, where there is huge emphasis on back-up systems. For obvious reasons. As regards Russia’s own GLONASS satellite guidance system, they are the only country with a fully functional alternative system to US based GPS, although China is currently in process of launching its own satellite guidance system. Obviously, GPS, being the first available system, and fully subsidized by US government, who pay the annual running costs at over $10 billion per-anum, has meant (as was intended) the US system has dominant international market share. And with that dominance comes vast end-user feedback, allowing it to develop at a very fast rate. The Russian, and newer Chinese alternatives, are at a market disadvantage, and will need to have own national based end-user system established first. But it is a strategic necessity to develop an alternative for those planning on being a competitor to US in international Geo-politics arena, rather than a US dominion.

US has capability to scramble GPS signal over certain area – so only its own military can make use of the signal. Therefore your assumption is wrong. It is just that US, obviously, did not scrambled GPS signal over Syria, so it stayed available for anyone to use.


whazup subsonic gimp,you can’t even change sparkplugs on a lada and you think you know the truth?

Always Verify

Do we know European standard is compatible with US products?

GARMIN – What is WAAS? https://www8.garmin.com/aboutGPS/waas.html

Currently, WAAS satellite coverage is only available in North America. There are no ground reference stations in South America, so even though GPS users there can receive WAAS, the signal has not been corrected and thus would not improve the accuracy of their unit.

Other governments are developing similar satellite-based differential systems. In Asia, it’s the Japanese Multi-Functional Satellite Augmentation System (MSAS), while Europe has the Euro Geostationary Navigation Overlay Service (EGNOS). Eventually, GPS users around the world will have access to precise position data using these and other compatible systems.


DGPS doesn’t need to have the correction signals broadcast over the same satellites. Any means of communication can be used – you can do even your own (a fixed receiver in the desired region to get the error, and some comm channel to send that data to the mobile units).


Reheating the broth? The same bullshit speculations were made not so many days ago…


Listen…these Garmin systems are more likely made in China and Taiwan than murica. They are not integrated into the navigation/attack systems of the planes, they are just there to check for spoofing, a wise idea considering they may be using satellite guided weapons.


The level of ignorance on military technology is astounding on sites such as this. You cant simply take a commercial gps system and stick it into an attack planes avionics. There is no way on hell’s earth one of these commercial machines would be able to off load data to the planes weapons systems! These devices are just sitting in the cockpit like they had a cell phone hanger in a car. They are not concerned about being unable to get a signal from glonass or gps on the internal navigation system. These devices would not help in such an event anyway. What they fear is that a false signal might try to fool the plane as to its position and cause it to send satellite guided munitions to the wrong location. With a commercial system they can check against that. The fact they are using these devices shows it has probably been tried against them already.

Or it may be that though now their system is good with the pilots and meets the requirements of the Russian military. Either way, getting rid of a known, reliable but foreign system for a backup that is already installed seems a nonstarter. All sides are aware of the ‘What can go wrong will go wrong’ at the wrong moment. That is why they did it in the first place.


GPS can be spoofed. Good idea to have a secomd one for corse (not course) confirmation. Plus US is less likely now to spoof civil GPS less all the nav systems in vehicles cause problens. Same with commercial aircraft. Look up when the US stopped spoofing civil GPS was partially because of the European system. GPS can be augmented in local areas with signals from special aircraft. Thus the WAAS i think.

Would love your thoughts, please comment.x
