SSR8000 GNSS Signal Recorder & Playback System
Capture, store, and replay real-world GNSS signals to reproduce complex navigation environments for receiver R&D testing, validation, certification-oriented workflows, and field-to-lab troubleshooting.
Capture real GNSS signal environments and replay them under repeatable lab conditions.
SSR8000 series GNSS signal recorder and playback systems support real-time navigation signal acquisition, storage, and signal playback. The system can reproduce complex real-world GNSS signal environments, helping engineering teams conduct navigation product R&D testing, receiver validation, certification-oriented testing, and field-to-lab troubleshooting workflows.
SSR8000 belongs to the Signal Recording & Playback product family. It is different from a GNSS signal simulator: instead of generating synthetic signal scenarios from configured parameters, SSR8000 records actual field signal data and replays it in the laboratory for repeatable receiver evaluation.
