GSA's GNSS Opinion Leaders

“Using multiple GNSS can significantly enhance signal acquisition, satellite visibility, spatial geometry and measurement redundancy,” said Bernhard Richter, Leica Geosystems GNSS business director. “We have always been about multi- GNSS and multi-frequency. Our users are not asking what ‘kind’ of position we give them; they are saying ‘Give us the best possible position’, period.”

We spoke to Richter about his company’s habit of pushing technological boundaries in the service of its very real-world clients.

Lockheed Martin Assembles Third U.S. Air Force GPS III Satellite

The U.S. Air Force’s third GPS III satellite in production flow at Lockheed Martin’s advanced satellite manufacturing facility in Denver is now fully integrated into a complete space vehicle.

GPS III Space Vehicle 03 (GPS III SV03) followed the first two GPS III satellites on a streamlined assembly and test production line. Technicians successfully integrated the satellite’s major components – its system module, navigation payload and propulsion core – into one fully-assembled space vehicle on August 14.

Contest to Build 22 New GPS III Satellites Commences Dec. 7

Air Force Space Command announced Wednesday it will begin the next phase of its plan to buy another 22 GPS III satellites in two weeks.

The November 22 posting on Fed Biz Opps (fbo.gov) said the highly anticipated Request for Proposals (RFP) would be released on or about December 7. The contract for the new space vehicles is "planned as a single, predominantly Fixed Price Incentive-type contract awarded via full and open competition for production of 22 GPS III SVs."

Next Tranche of GPS Satellites to be called GPS IIIFs

The Global Positioning Systems Directorate, which is poised to launch its procurement of another 22 GPS III satellites, has given its next tranche of spacecraft a name.

"We are officially calling this GPS IIIF," Col. Gerry Gleckel, the Directorate's deputy director, told the November meeting of the National Space-Based Positioning, Navigation, and Timing (PNT) Advisory Board. "Just as there was a IIF that was the follow-on for the GPS II's, this is the follow-on for the GPS III."

Spoofing-Resistant UAV Application Earns Top Honors at European Satellite Navigation Competition

The SORUS system, designed to enable user receivers to calculate Galileo PRS positions at predefined points in time including robustness against jamming and spoofing, picked up top honors at the 2017 European Satellite Navigation Competition (ESNC).

SORUS, a novel satellite navigation-based solution, enables Galileo Public Regulated Service (PRS) navigation for a wide range of users while significantly reducing security requirements and Galileo PRS costs per user device.
