An additional delay in release of the GPS III RFP emerged just as federal watchdogs released a new report detailing the challenges Air Fore managers will face in keeping all the components of the modernization program on track.
The long-expected report from the Government Accountability Office looks at the overall effort to update GPS including developing a new ground system, more capable receiver cards for military equipment and new satellites to sustain and improve the constellation.

Close to 300 users attended the 1st Galileo User Assembly, held in Madrid, Spain on November 28-29. The users, along with several expert presenters, came together for the first EGNSS User Consultation Platform to share their experience, discuss their needs and provide feedback on Galileo performance, one year after the launch of Galileo Initial Services.

The Army is kicking off a wide-ranging, five-year research effort to develop new position, navigation and timing (PNT) technologies for battlefield use.
The goal is to overcome technical barriers in a wide range of areas and military officials are offering to fund multiple, and even multi-phase, cost-plus-fixed-fee (CPFF) efforts to do that. The work may range from studies and analysis to development work that results in the production of a prototype-style deliverable or breadboard and/or a demonstration.

A highly anticipated presentation by Ligado Networks to the nation’s leading satellite navigation experts took an unexpected turn when the company said it could not provide essential network information because it was looking to the government for technical direction and its business plans were still in flux.
