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

A new dimension in real-world PNT testing has arrived. One of the most critical things to predict for chips, receivers and devices using alternative or back-up PNT technologies is how they will actually perform without GPS. Filling this need, the U.S. Air Force 746th Test Squadron has declared Initial Operational Capability (IOC) for its new truth reference, the Ultra High-Accuracy... 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
