[Satellite TODAY 04-12-13] STMicroelectronics has announced that its Teseo II single-chip satellite-tracking ICs performed successfully in the first ground location test using Europe’s independent navigation system, Galileo. The European Space Agency (ESA) conducted the tests at their technology center in the Netherlands, and ST collaborated from its Global Navigation Satellite System (GNSS) software development labs in Italy.

 

ST’s Teseo II is a single-chip standalone satellite receiver able to use signals from all of the satellite navigation systems such as GPS, the European Galileo system, Russian GLONASS, and Japanese QZSS. The chip provides shorter time-to-first-fix and continuous tracking with enhanced accuracy.

 

For the Galileo test, ST and ESA used a rooftop antenna with a clear view of the satellites (static) and a mobile test-bed unit travelling in a normal user environment (dynamic) to perform the test. The Teseo II receiver was able to track and produce a 3D fix over the entire path of the mobile unit, using only the four Galileo IOV satellites.
