The space-based Automatic Identification System (SAT-AIS) is devised to provide identification and position information to vessels for maritime safety and security purposes. The system is intended to operate at VHF through mini-satellite platforms in Low Earth Orbit (LEO). Due to the in-orbit deployment of the antenna array and overall mass requirements for the satellite, the array element minimization...
An important satellite based application at VHF band is the Automatic Identification System (AIS). The system is devised to receive messages sent by vessels for maritime safety and security purposes. The intended platform is a mini-satellite in Low Earth Orbit (LEO). Due to the in-orbit deployment of the array and overall mass requirements for the satellite, the array element minimization and mass...
Accurate measurements on low gain antennas at VHF frequencies are very demanding due to the limited dimensions of available test ranges. This paper presents the findings and post processing issues involved in the verification measurement on a low gain VHF antenna array element with minimized mass and dimensions developed for space application and suitable for an Automatic Identification System (AIS)...
