GPS Control Software Glitch: NANU Issued
http://www.gpsworld.com/gnss-system/...d-9414?print=1
January 21, 2010

The GPS AEP Command and Control operational software update previously
reported enables new capabilities for the warfighter. The new
capabilities are not something we can discuss in this venue. They are
considerable, but require absolute compliance with the published GPS
Interface Control Document (ICD). Some of the new features that are
incorporated only work with authorized military receivers that have
successfully passed security tests. However the live introduction of the
new functions is causing problems wherein some of these receivers are
intermittently not tracking Y-code, and non-compliant civilian receivers
are also reporting continuing problems.

Corrective action could encompass either the Air Force rolling back the
update or revising its software, or the manufacturers modifying GPS
software within the receivers to be totally compliant with the ICD.

In November and December 2009, the new software uploaded operational GPS
IIA and IIR space vehicles with navigation data and completed normal
operational functions. The software is part of the GPS modernization
effort, with its principal features being telemetry, tracking, and
commanding for the new GPS IIF space vehicle — as yet unlaunched -- and
more robust security for the military M-code signal.

On January 24, the GPS Wing issued the following notice:

NOTICE ADVISORY TO NAVSTAR USERS (NANU) 2010011 NANU TYPE: GENERAL
