GPS CNAV Debate, and GNSS Interoperability Moves Forward

March 27, 2014By

The most modernized GPS satellites on orbit will broadcast a new civil navigation message (CNAV) on the L2C and L5 signals in April. That's the plan, at least. An update on the CNAV debate in the United States. Also, summaries of key presentations from the international committee charged with inter-GNSS compatibility and interoperability. read more

Quad-Constellation Receiver: GPS, GLONASS, Galileo, BeiDou

January 8, 2014By

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. read more

GNSS RF Compatibility Assessment: Interference among GPS, Galileo, and Compass

December 1, 2010By

A comprehensive methodology combines spectral-separation and code-tracking spectral-sensitivity coefficients to analyze interference among GPS, Galileo, and Compass. The authors propose determining the minimum acceptable degradation of effective carrier-to-noise-density ratio, considering all receiver processing phases, and conclude that each GNSS can provide a sound basis for compatibility with other GNSSs with respect to the special receiver configuration. read more
