1.       Product Description
The DVBEI DBS-08 series navigation signal source supports signal simulation of four satellite navigation systems BDS/GPS/GLONASS/GALILEO, providing users with stable, reliable, accurate and controllable GNSS simulated signals, and is a special test equipment for satellite navigation product development testing and inspection and certification. With the selection of relevant components, the DVBEI DBS-08 series navigation signal source can support signal simulation for special applications such as real-time closed-loop, combined INS/GNSS, multi-antenna and multi-user.
 

2.       Product features：
Ø  All-system all-frequency: generates BDS/GPS/GLONASS/Galileo and other satellite navigation system all-frequency signals and SBAS satellite-based augmentation signals.

Ø  Simulation of complex characteristics: for applications such as high-precision positioning, integrity monitoring and precision guidance, with simulation capabilities for special requirements such as signal quality anomalies, non-ideal transceiver channels, complex multipath environments, ionospheric dispersion effects and spin carrier received signals.

Ø  Flexible expansion of components: support the expansion of different components on the basic hardware platform, with RTCM differential positioning, GNSS/INS combined navigation, array antenna signal simulation and other functions to meet the needs of various navigation receiving terminal development and testing.

3.       Support for multiple cascades: Multiple devices can be cascaded to achieve large-scale multi-antenna or multi-user signal simulation, providing a flexible solution for individual user requirements.
