GNSS RF Record and Playback

GNSS RF Record and Replay systems allow you to bring the real world GNSS signals into the lab for testing. The recorded signals include the fades, multipath and interference that you get in the real world, especially in dense urban environments. Using these real signals in the lab reduces your field trial costs and speeds your time to market.
