VSBT VHF Ship Borne Terminal Integrating Surveillance and Data Exchange Services


  • 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


  • Simultaneous support of AIS/ASM/VDE
  • Multiple receive antennas
  • Full duplex option
  • Interference mitigation
  • HPA linearization


Today, no products exist with support for AIS/ASM/VDE in both the satellite and terrestrial segments. Integrating all services into one unit offers a great advantage for the customer, both in functionality and reduces footprint. The product will be compatible with existing Kongsberg Seatex AIS installations, to ease the upgrade of existing vessels with VDES.


  • Simultaneous support of AIS/ASM/VDE
  • Both satellite and terrestrial support
  • High receiver sensitivity
  • Rugged design for harsh environment
  • Multiple receive antennas
  • USB interface for firmware upgrade
  • Web interface for remote configuration and SW upgrade
  • Reception of all types of internationally approved AIS messages

System Architecture

The proposed architecture consists of three different boards:

  • Transceiver board – PA, receivers and digital design
  • Interface board – Power supply and external interfaces
  • GNSS board – PPS and timestamping using GPS/GLONASS/Beidou/Galileo


The project consists of the following phases and milestones:

  • Requirements consolidation – SRR
  • Design and definition – DR
  • Manufacturing phase and test planning – TRR
  • Verification phase and completion – FR

Current status

The project is currently in requirements consolidation phase
