The USAF’s 746th Test Squadron (746 TS) has tested its Non-GPS-Based Positioning System (NGBPS) at White Sands Missile Range as an alternative to GNSS for precise time transfer and synchronization.
This was the first independently measured and characterized testing program for the Non-GPS Based Positioning System (NGBPS), which leverages Locata’s radio-based position, navigation and timing (PNT) technology to achieve high accuracy independent of GPS.
“Independent Government experts from the United States Naval Observatory (USNO) demonstrated and analyzed Locata’s absolute and relative time synchronization and frequency stability performance over RF link distances of more than 73km. Under testing, Locata provided exceptional sub-nanosecond time transfer and frequency stability across large areas.”
“With these successful results in hand, the U.S. Department of Defense will be able to leverage this capability for programs requiring high-precision time and frequency distribution, without relying on GPS alone. Plus, the system is flexible — Locata’s area of transmission can be increased to cover substantially larger areas than at White Sands for safety-of-life, military or government-mandated systems.”
