Air Force upgrades to better field reference system for testing GPS denial

Non-GPS positioning system, White Sands North Range. X = transmitter site.

Can’t Deny the Truth: Defeating the Jamming Threat Initial Operational Capability for the Ultra High-Accuracy Reference System has been declared by the U.S. Air Force. Even when GPS is being completely jammed, UHARS provides extremely accurate positioning, navigation and time — more accurate than GPS — over the large area of White Sands Missile Range in New Mexico. Amid a... read more
