Helicopter videoing is one of the most popular methods to acquire on scene information for disaster management and relief. We developed an on scene disaster information transmission system using Ku-band helicopter satellite communications. The main obstacle for a helicopter satellite communication link is the interruption by the rotating blades of the helicopter. To overcome the blade interruption, we use a time diversity transmission technique at the forward link and a blade-synchronized transmission technique at the return link. Furthermore, onboard position estimation is done for the on scene videoing pictures. Some primary field experiments have been done with satisfactory results.
