Newly developed lightweight parabolic antenna, strong FEC(LDPC) and H.264 codec enables high-speed, high-definition video transmission from the helicopter.
Automatic tracking system captures satellite instantly and keeps tracking while in flight or hovering.
Stable transmission technique (time diversity reception and intermittent transmission) avoids satellite signal blockage by blade rotation.
Entire system can be controlled from a ground station, including bandwidth assignment for multiple helicopters and bidirectional voice communication between helicopters and ground stations.
(*1)Transmission rate depends on the satellite conditions.
●10Mbps high-definition video transmission*1
●Steady transmission everywherewithout interruption from mountains or buildings
Helicopter Satellite Communications System (HSA)
●Burst modem synchronization through blade rotation
