Air Force jam-proof test range ready; Galileo teendom

July 7, 2016By
Locatalite transceiver installation in the White Sands Missile Range Ultra High-Accuracy Reference System, provided by the U.S. Air Force for testing equipment under conditions of GPS jamming.

Provides high-accuracy PNT even when GNSS jammed A critical capability to predict for GNSS chips and receivers —and for devices using alternative or back-up PNT technologies — is how they will actually perform without GPS. Filling this need, the U.S. Air Force 746th Test Squadron has declared Initial Operational Capability (IOC) for its new truth reference, the Ultra High-Accuracy Reference... read more

Assured PNT for Our Future: PTA

September 1, 2014By

Actions Necessary to Reduce Vulnerability and Ensure Availability By Brad Parkinson (From the 25th Anniversary GNSS History Special Supplement) Introduction About 40 years ago, we had a vision for positioning, navigation, and timing (PNT). That vision was more than successful, and became known as GPS. In some respects we have been almost too successful: PNT is frequently taken for granted.... read more
