GLONASS ( Russian : ГЛОНАСС , IPA:  [ɡlɐˈnas] ; Глобальная навигационная спутниковая система ; transliteration Globalnaya navigatsionnaya sputnikovaya sistema ), or "Global Navigation Satellite System", is a space-based satellite navigation system operating in the radionavigation-satellite service and used by the Russian Aerospace Defence Forces . It provides an alternative to GPS and is the second alternative navigational system in operation with global coverage and of comparable precision.

Manufacturers of GPS devices say that adding GLONASS made more satellites available to them, meaning positions can be fixed more quickly and accurately, especially in built-up areas where the view to some GPS satellites is obscured by buildings. Smartphones generally tend to use the same chipsets and the versions used since 2015 receive GLONASS signals and positioning information along with GPS. Since 2012, GLONASS was the second most used positioning system in mobile phones after GPS. The system has the advantage that smartphone users receive a more accurate reception identifying location to within 2 meters. [1]

Development of GLONASS began in the Soviet Union in 1976. Beginning on 12 October 1982, numerous rocket launches added satellites to the system until the constellation was completed in 1995. After a decline in capacity during the late 1990s, in 2001, under Vladimir Putin 's presidency, the restoration of the system was made a top government priority and funding was substantially increased. GLONASS is the most expensive program of the Russian Federal Space Agency , consuming a third of its budget in 2010.

Advanced interception systems for GSM, 3G, 4G (CDMA, UMTS, LTE) and Satellite Networks. Unique features, user friendly operation and full post sale support.


Our latest generation real time GSM interception system is designed to off air interception for cellular GSM networks. The system is portable and lightweight allowing you to deploy it and become ready to start interception in the unknown environment within a few minutes, undetected by the target phone.


A passive real time monitoring system that intercepts voice and text (sms) traffic in CDMA, UMTS & LTE networks: user friendly interface, wide working range, fast and completely transparent interception, supports all CDMA frequency bands, deployment within minutes, does not interfere with networks and mobile phones.

The implementation changes and first live tests of BeiDou and Galileo on Teseo-3 GNSS chips developed in 2013 are covered, bringing it to a four-constellation machine. By 2020, we expect to have four global constellations all on the same band, giving us more than 100 satellites — under clear sky, as many as 30 or 40 simultaneously.

Multi-constellation GNSS first became widely available in 2010/2011, but only as two constellations, GPS+GLONASS. Although receivers at that time may have supported Galileo, there were no usable satellites. BeiDou was a name only, as without a spec (an interface control document, or ICD), no receivers could be built. However, the hardware development time of receivers had been effectively shortened: the Galileo ICD had been available for years, BeiDou codes had been reverse-engineered by Grace Gao and colleagues at Stanford, and at the end of 2011 they were confirmed by the so-called test ICD, which allowed signal testing without yet releasing message characteristics or content.

The Teseo-3 receiver appeared late in 2013, returning to the optimum single-chip form factor: RF integrated with digital silicon and flash memory in the same package, enabling simultaneous use of BeiDou and GPS/Galileo signals. Multi-constellation in 2012 was GPS+GLONASS, which brought huge benefits in urban canyons with up to 20 visible satellites in an open sky. Now, for two hours a day in Europe while the Galileo IOVs are visible, we can run three constellations, and in the China region, GPS/BeiDou/Galileo is the preferred choice.

It's a great time to buy a GPS device. The category has fully matured, and competition from nav-equipped smartphones has helped drive prices way, way down. As a result, you can get a capable stand-alone GPS that can do much more than just help you find your way, for a lot less than you would have paid just last year. Still, there are several factors to consider when choosing the right GPS: Do you need a big display? Should you spring for a live traffic subscription? Lifetime map updates? Should you even bother with a GPS, or can you just use your phone for directions? Here's what you should consider when navigating the GPS market.

Virtually every GPS you buy today will come with preloaded maps for the United States—some also include a combination of Canada, Mexico, or Puerto Rico too. (If there's an "M" in the product name, it typically stands for "maps.") If you need additional maps, you can usually buy them from the device manufacturer and download them via PC.

Since construction is inevitable and roads are constantly changing, keeping your maps up to date is also important. These days, most vendors include free or one-time-pay map updates for a wide variety of the devices they sell. (The aforementioned TomTom VIA 1535TM and Garmin nüvi 3590LMT both come with free lifetime maps.) But some companies charge for each map update—and they can be expensive. Be sure to check the map-update policy before you settle on a particular model. And if you buy an older model, make sure you update the maps before you hit the road.
