Munich Summit Highlights Satellite Navigation Plans, GNSS Program Struggles


Highlights of the 2009 Munich Satellite Navigation Summit (March 3- 5):
Russia will place its first CDMA signal on the GLONASS L3 frequency that overlaps the European Galileo E5b spectrum; China plans to launch three Compass satellites this year and seven more next year to provide a regional capability for Compass/Beidou, followed by completion of the full 30-MEO, 5-GEO constellation after 2015 and before 2020; Galileo program discussions revealed tensions around negotiations with China about a frequency overlay of Compass signals on the security-oriented Public Regulated Service as well as the question of whether the costs to build Galileo can be kept within the €3.4-billion limit agreed by the European Council and the European Parliament; the GPS Block IIR-20(M) satellite with an L5 demonstration payload will be launched later this month in what may be the program's last chance to secure primary GPS access to the frequency.
