Working Principle
The GNSS Signal Recorder and Replayer (NavS X3004) supports two recording scenarios: recording live navigation signals from real-world environments for playback, and recording signals from standard GNSS simulators for playback. Live environment signals are captured via receiving antenna, while simulator signals can be recorded either through an antenna or via direct cable connection.
