Patent ID: 8081210

Claim:
A system for improving reception of broadcast television signals at a moveable platform from a broadcast tower, said system comprising: a GPS receiver provided on the moveable platform that provides information identifying the location of the moveable platform; a map database provided on the moveable platform that identifies the location of features around the moveable platform including the location of the broadcast tower, said map database storing information about dead zones and/or channel characteristics of the broadcast signals from the broadcast tower, where the dead zones may be caused by terrestrial or structural obstructions; a television receiver provided on the moveable platform that processes broadcast signals received from the broadcast tower, said television receiver taking preventative measures if the moveable platform is in a dead zone or adversely affected by channel characteristics; and an antenna provided on the moveable platform that receives the broadcast signals from the broadcast tower and sends the broadcast signals to the television receiver to be processed, said television receiver correcting a Doppler shift caused by the motion of the moveable platform relative to the broadcast tower by determining a forward vector based on the speed and direction of the moveable platform and a tower vector based on the speed and direction of the moveable platform relative to the broadcast tower and using the forward vector and the tower vector to determine the relative speed of the moveable platform to the broadcast tower.
