The Air Force Research Laboratory (AFRL) has selected Surrey Satellite Technology US LLC (SST-US), of Englewood, Colorado, to investigate cost reduction and augmentation of the current GPS constellation through the application of a small satellite approach.
AFRL has contracted with SST-US to identify and analyze how small satellites can improve aspects of GPS system performance, such as accuracy, coverage, and robustness at costs far below those of past procurements.

GPS contractors are scrambling to assess new Pentagon budget-cutting directives that have the potential to slow GPS modernization.
The belt-tightening is in response to a three-way fiscal vise created by the failure of Congress and the White House to agree on a budget for this year, on a new limit for the nation’s debt, and on a plan to implement future budget cuts.

Do we need performance specs for GNSS user equipment design? For a long time, the signal-in-space interface guidelines provided enough technical guidance. But times have changed.
Over the past two years, the effort by LightSquared to persuade the FCC to allow it to operate high-powered terrestrial transmitters in frequencies adjacent to GPS focused attention on potential vulnerabilities of GNSS user equipment.
