The activity provided a first feasibility assessment of maritime VHF Data Exchange via satellite (VDE-SAT) with the aim of
VDE satellite component is a relevant solution for:
The keywords for this technical solution:
The proposed solution is based on a constellation of Small satellites (between 12U-nano and small-micro) on a low orbit around 600 Km with a lifetime of at least 4 years and based on 6 satellite launch configuration.
The constellation solution for each use case includes a total of 6 up to 24 satellites.
Concerning the payload, the solution is based on a Yagi antenna for the uplink and on-board processing for the uplink and the downlink using a multi core processor. Based on the performance required by the use case and cost limitation, the satellite solution is half-duplex or full duplex.
For ground segment, the proposed configuration uses classical S-Band solutions for polar and equatorial control stations, and ad-hoc station in areas of interest requiring reduced timeliness (military and security domain)
The activity was divided into 3 major tasks:
The study has been completed.
