Objectives
- Critical review of VDES/ASM/AIS standards for the purpose of developing a mature ship borne transceiver for maritime applications
- Ensure the design is compliant to VDES specifications and carefully evaluate future revisions of standard
- Design, develop, manufacture and test a prototype VDES terminal supporting VDE (TER/SAT), ASM (TER/SAT) and AIS in one unit
Challenges
- Simultaneous support of AIS/ASM/VDE
- Multiple receive antennas
- Full duplex option
- Interference mitigation
- HPA linearization
System Architecture
The system architecture consists of three functional modules on one common board:
- Transceiver module – PA, receivers and digital design
- Interface module – Power supply and external interfaces
- GNSS module – PPS and timestamping using GPS/GLONASS/Beidou/Galileo
