Experts at Telit decided to test what impact the Russian Global Navigation Satellite System (GNSS) has on satellite navigation and positioning. They conducted tests in Los Angeles and London to see the relevance of Glonass for the whole world. The results clearly showed that the combination of GPS and GLONASS, found in modules like Telit's SL869, improves positioning tremendously.

At the end of 2011 the Russian government announced that GLONASS, the Russian Global Navigation Satellite System (GNSS), is fully operational and has global coverage. Experts at Telit decided to test what impact this has on satellite navigation and positioning. They conducted tests in Los Angeles and London to see the relevance of GLONASS for the whole world.

The results clearly showed that the combination of GPS and GLONASS improves positioning tremendously. Especially in urban canyons with huge skyscrapers the receiver had the ability to track at least four satellites and thus calculate a fix – which was impossible to guaranty using only GPS. Thanks to the SL869, a newly released Global Navigation Satellite System (GNSS) module from Telit that has access to both GLONASS and GPS, blind spots were reduced and navigation performance was radically improved. This white paper shows the test set-up and examines the results. For the future further tests are planned, for example in South Africa.
