  • Satellite signal propagation delay test device
    Patent number: 12498676
    Abstract: A test device determines a Global Navigation Satellite System (GNSS) signal propagation delay in a GNSS signal distribution system (GSDS) for a radio access network, and can further perform long-term tests on a GSDS without having access to a GNSS satellite. The test device includes a GNSS receiver and a clock that can be re-tuned to accommodate performing tests on the GSDS.
    Type: Grant
    Filed: October 24, 2022
    Date of Patent: December 16, 2025
    Assignee: VIAVI SOLUTIONS INC.

  • SATELLITE SIGNAL PROPAGATION DELAY TEST DEVICE
    Publication number: 20250093523
    Abstract: A test device determines a Global Navigation Satellite System (GNSS) signal propagation delay in a GNSS signal distribution system (GSDS) for a radio access network. The test device includes a GNSS receiver. The GNSS receiver is connected at different times to a reference GSDS with a known signal propagation delay and to a device under test (DUT), including a second GSDS having an unknown signal propagation delay.

    Patent number: 12130368
    Abstract: A test device determines a Global Navigation Satellite System (GNSS) signal propagation delay in a GNSS signal distribution system (GSDS) for a radio access network. The test device includes a GNSS receiver and a clock. The GNSS receiver is connected at different times to a reference GSDS with a known signal propagation delay and to a device under test (DUT), including a second GSDS having an unknown signal propagation delay. One pulse per second (1PPS) signals are generated by the GNSS receiver and are compared to determine the unknown signal propagation delay of the DUT.
