GLONASS launches No. 53 to replenish constellation

May 31, 2016By

On May 29 a Soyuz-2.1b with upper stage Fregat and a GLONASS-M satellite (No. 53) successfully lifted off from Plesetsk Space Center. The satellite was placed into its preprogrammed orbit and registered by the facilities of the Titov Main Test and Space Systems Control Centre. Ground control established communications with it. The stable telemetry link shows that onboard satellite systems... read more

Iridium launches alternative GPS PNT service

May 23, 2016By

Iridium Communications Inc. has introduced its Satellite Time and Location (STL) service, an alternative or complement to traditional indoor and outdoor location-based technologies, and declared it ready for use. STL’s position, navigation and timing (PNT) technology is deployed through Iridium’s 66 cross-linked, low-earth orbit satellite constellation. Through Iridium satellites and in GNSS receivers, STL technology can work to verify GPS, GLONASS, Galileo and... read more

Expert Opinions: How many GNSS signals for a consumer-grade device?

December 23, 2015By
Greg-Turetzky-T

Question: What is the optimum number of GNSS signals to include/process in a consumer-grade PNT device? A: A chip should support four signals, being GPS/GLONASS/Galileo/Beidou, but only process two of them — choice depending on region, geopolitical sensitivity, constellation availability — dropping to one to save power when satellite availability is good. Two constellations give enough satellites for accuracy and... read more
