Abstract

The Very High Frequency (VHF) Data Exchange Systems (VDES) addresses the need to protect Automatic Identification System (AIS) and provides essential digital communications contributions for e-Navigation and Global Maritime Distress and Safety System (GMDSS). As the satellite component of the VDES, VDE-SAT faces many technical challenges. Due to its global broadcasting nature, the signal emission of the newly added VDE-SAT satellite stations and its interference to the incumbent or future land mobile systems in shared bands is of a major concern in ITU spectrum allocation. This paper studies the existing regulations on the protection of the land mobile systems proposed by Electronic Communication Committee (ECC) and International Telecommunication Union (ITU) via the power flux density (PFD) concept. We infer the PFD masks from the two regulations and then show the corresponding impact on the VDE-SAT performance.
