The recent release, in December 2012, of the complete BeiDou B1I Interface Control Document has boosted new interest and R&D activities in the field. For a manufacturer of GNSS semiconductor devices, the first and logical step in the roadmap toward a full blown BeiDou receiver is the reuse of existing and proven silicon; the new product can blossom and reach the market more quickly, with good...
Initial results using Teseo-2 to track both Galileo IOV satellites and Compass MEO satellites are presented showing that the hardware is ready for the full constellations in both cases. Development software under test awaits satellite availability for full field testing. Future plans for other constellations and dual bands are discussed.
Both Galileo E1 OS and GLONASS L1 signals require a wider pre-correlation bandwidth than GPS C/A. The GLONASS channels are uniformly spaced on a frequency division grid, and occupy some 8MHz in total, whereas Galileo E1 OS has sidebands that are separated by about 2MHz. Being wideband is an advantage because of sharper correlation peak (Galileo) and better interference rejection; however it also exposes...
Consumer Multiconstellation silicon started with GPS-Galileo around 2007 [1], but with Glonass satellites available before Galileo, was first seen publically Teseo-2, STA8088, in 2010/11 [2,3,4]. With QZSS, Compass, GPS-L1C, Glonass-CDMA all expected, the silicon manufacturer must continue the path towards the fully flexible multi constellation receiver, otherwise the number and rate of new required...
