Key benefits

  • Supporting all current and future civilian constellations and frequencies, with up to 256 channels and 2 independent RF outputs ,the GSS7000 enables comprehensive testing in all commercial applications.. In addition, the GSS7000 enables users to generate multiple GNSS signals within the same frequency band on a single channel bank. Upgrades can be easily applied in the field and remotely, meaning the GSS7000 can grow with your test needs.

    • 100 Hz update rate - enabling low latency testing in high dynamics and hardware-in-the-loop configurations
    • 30 km/s relative velocity
    • 2 km/s2 relative acceleration
    • 22 km/s3 relative jerk
    • 10π rad/s angular rate
    • 0mm static/3mm maximum dynamics RMS pseudorange accuracy

    The GSS7000 meets all performance specifications under all test conditions.

  • The GSS7000 can generate up to 256 concurrent signals whilst maintaining all performance specifications at its maximum SIR (100 Hz).

    • Tx and Rx antenna gain and phase pattern
    • Ionosphere and troposphere
    • Pseudorange ramps for RAIM testing and spoofing
    • Vehicle motion

  • The GSS7000 is available with 3 levels of software built on Spirent’s positioning application engine. In addition, Single Channel Utility enables a remote command based and low-cost option for R&D and production testing.

    Spirent’s flagship software platform, SimGEN, is the most powerful tool available to GNSS test and development teams. For more information and a full specification on SimGEN please visit

  • The GSS7000 is designed to work flawlessly with a number of complementary tools. These include:

    • Sim3D – realistic multipath testing with 3D models
    • SimHIL – API with software interface for hardware-in-the-loop test integration.
    • SimSENSOR – emulate the output of key MEMS sensors
    • SimREMOTE – powerful remote command function
    • GSS7725 – complex interference testing
