All CGSIC:

Posting of new GPS SPS Performance Standard

The U.S. Air Force has released the 5^th Edition of the GPS Standard Positioning System (SPS) Performance Standard (PS).  With final signature by the Department of Defense, it was cleared for public release on 16 April, 2020.  This is the first update to the SPS PS since 2008 and, for the first time, includes pre-Initial Operating Capability (IOC) performance standards for new civil GPS signals L2C and L5, in addition to L1 C/A.

The SPS PS specifies the levels of SPS performance in terms of broadcast signal parameters and GPS constellation design. The U.S. Government is committed to meeting and exceeding the minimum levels of service specified in the SPS PS.  The document can be found at  https://www.navcen.uscg.gov/?pageName=gpsTechnicalReferences and at GPS.gov https://www.gps.gov/technical/ps/#spsps.
