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

January 1, 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

The European Space Agency’s Galileo satellites have achieved their first aerial fix of longitude, latitude and altitude, enabling the inflight tracking of a test aircraft. ESA’s four Galileo satellites in orbit have supported months of positioning tests on the ground across Europe since the first fix in March. Now the first aerial tracking using Galileo has taken place, marking the... read more

GNSS Simulator in R&S SMBV100A Now Supports BeiDou

November 25, 2013By

Rohde & Schwarz extends the functionality of the R&S SMBV100A vector signal generator by adding BeiDou/Compass capability to its integrated GNSS simulator. With the R&S SMBV-K107 option, the GNSS simulator now covers the BeiDou standard as well as the GPS, Galileo and GLONASS satellite navigation systems. The new option allows users to generate real-time scenarios with up to 24 BeiDou satellites. R&S SMBV-K107... read more
