Satellite-tracking ICs from ST power Galileo' navigation sys

STMicroelectronics has announced that its Teseo II single-chip satellite-tracking ICs were successful in the very first ground location test using Europe’s own independent navigation system, Galileo. The tests were conducted in collaboration with the European Space Agency (ESA). Last month, the first position fix of longitude, latitude and altitude using the four Galileo satellites currently in orbit was performed by the European Space Agency at its Technology Centre in the Netherlands and by ST at its GNSS (Global Navigation Satellite System) software development labs in Naples, Italy. ST and ESA conducted the historic static and dynamic tests using a rooftop antenna with a clear view of the satellites (static) and from a mobile test-bed unit travelling in a normal user environment (dynamic). The Teseo II receiver was able to track and produce a 3D fix over the entire path of the mobile unit, using only the 4 Galileo IOV (In-Orbit Validation) satellites. ST and ESA plan to continue the joint tests, initially as a combined multi-constellation fix with GPS and/or Glonass satellites, then later in the year, when more Galileo satellites are available, they also plan Galileo-only tests in a hostile environment. ESA and ST have been cooperating on a project to evaluate the performance of low-cost consumer and automotive GNSS receivers with the Galileo signals, combining ES...
