FIGURE 1: Characterization of interference from the user perspectiveIncreasing demand for ensuring the authenticity of satellite signals and position/velocity/time (PVT) calculations raises the need for tools capable of assessing and testing innovative solutions for verifying GNSS signals and PVT. Today’s civilian systems do not provide authentication at the system level, and a number of mitigation strategies have been developed in the last 10 years at user segment in order to protect receivers from interference and deception.

Francine Vannicola, Naval Research LaboratoryAs the forthcoming “Time and Navigation” opening next March at the Smithsonian National Air and Space Museum reminds us, modern navigation depends profoundly upon time — the more precise, accurate, and stable a navigation system’s timing is, the more precise, accurate, and stable its positioning capability.

UrsaNav LF transmitter site for timing synchronization trialsVirginia-based engineering firm UrsaNav Inc. has begun transmitting a variety of low frequency (LF) test signals, including enhanced Loran (eLORAN), as part of a cooperative research and development agreement (CRADA) with the U.S. Coast Guard (USCG).
The test program include a comprehensive palette of signals that are being evaluated for their ability to provide a robust, wide-area, wireless precise timing alternative that can operate cooperatively with GNSS technology or autonomously during GNSS unavailability.
