Within weeks of a bilateral working group’s recommendation for a common civil GNSS signal design, the European Galileo and U.S. GPS programs have filed draft interface specifications (IS) or interface control documents (ICDs) for the new signals planned for the L1 frequency (around 1575 MHZ).

The Bush Administration’s Fiscal Year 2007 (FY07) budget proposal for the Department of Defense (DoD), announced in February, allocates $315,314,000 in advanced technology development for GPS, including work on the GPS III program. If approved by Congress, that would represent a sizable increase from the FY06 expenditures of more than $85 million and $33 million in FY05.

The Russian Space Forces are continuing efforts to bring the final two GLONASS spacecraft launched December 25 into operation.
One of the trio of satellites (SV798 in slot 19) went on the air in late January. Reports from the Russian news agency RIA Novosti, quoting Russian space officials, subsequently attributed the delay to frozen fuel lines in the satellites.

Civil GPS users now have a second full signal available to them — albeit on only one satellite and “at the user’s own risk” — courtesy of the first modernized Block IIR (IIR- 14M) spacecraft launched last September. And the world’s geodetic community is already moving to take advantage of it with announcement of an addendum to the receiver autonomous exchange (RINEX) format used to combine high-precision position data from different types of GPS receivers.
