Army Launches 5-Year PNT Technology R&D Program

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.

Fundamental Rethink for Galileo Commercial Service

At the lavish European Satellite Navigation Competition Awards Ceremony, we caught up with Carlo des Dorides, general director of the European GNSS Agency (GSA), who updated us on the status of the much-anticipated Galileo Commercial Service (CS).

“On the CS, we are dialoging extensively with EU member states, because there is a more and more consolidated view that there could be an advantage to providing the service for free,” des Dorides said.

Ligado: Business and Network Plan Remain Unclear

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.
