GNSS record/playback system launched

Corporate Member Spirent has introduced a new multi-frequency GNSS record and playback system.

Spirent Communications has launched the GSS6425 multi-frequency GNSS record and playback test system (RPS).

Compared with other systems, it claims to provide RF recordings for more constellations (GPS, GLONASS, Galileo, BeiDou, QZSS), more frequencies (L1, L2, L5) and wider bandwidth (30MHz) - and has more features to support a wide range of positioning and timing test applications.

GSS6425 is self-contained and portable, allowing users to record and playback data in the field without the need for an additional PC or external power - it is simple to faithfully capture and replay complex signal conditions, such as urban environments and dense forests, and indoor spaces like airport terminals.

Hence multiple environments can be brought into the lab and replayed in a repeatable and controlled manner, helping developers improve receiver and system performance.

Users can select and record 3 GNSS frequency bands at any one time, each with up to 30MHz bandwidth. If more than 3 concurrent channels are required, 2 units can be synchronised in a master-slave configuration. For example, survey-grade receiver developers can capture GPS L1, L2 and L5 signals, GLONASS L1 and L2, plus satellite-based augmentation system (SBAS) signals.

The GSS6425 is also capable of recording additional sources including inertial and DR sensor outputs and vehicle bus data.
