Applications:
SDI-204GNSS Board is mainly specialized in the fields of aviation, special vehicle, shipboard system, high-accuracy measurement, etc. Especially it is fit for the carrier who have the need of overload, velocity and environmental adaption.
Features:
- Raw data can be outputted;
- High-dynamic and anti-interference;
- Working condition can be changed by external command;
- Direct acquisition and guided acquisition of military code;
- Compatible with JNS100 and directly connect to BDS;
- Tracking single-frequency of BDS, GPS, GLONASS and multi-frequency of multi-system.
