Marine Stabilized Antenna System
Auto-Tracking Stabilised Antenna System is specifically used in the marine industry for offshore VSAT communication. Stabilised Antenna System allows the antenna to maintain an accurate pointing to the satellite regardless of the marine vessel movement.
Stabilised Antenna System consist of antenna (size ranging from 0.96 meter up to 2.4 meter equivalent) housed in a radome. The antenna is mounted on 3-axis pedestal with high-torque motors that control the antenna movement. This allows unlimited 360° azimuth turning and 0° to 90° elevation range. This movement is controlled by the Auto-Tracking Controller that gets vessel movement reading from the vessel onboard gyro-compass or external GPS compass system.
The system can compensate vessel movement of up to +/- 20° roll and up to +/- 15° pitch. This translates to stabilisation accuracy of less than 0.2° peak mispointing in full motion.
The stabilised antenna system can work with any of the VSAT solution, in particular the SCPC network. This solution is being used widely onboard sea vessels such as tankers, offshore FPSO (Floating Production, Storage and Offloading Vessel), semi-submersible drilling rigs, ships and cruisers.
