Abstract
A method and system for ground station signal handoff for an aircraft. The method comprises receiving signal quality data and position data from each of a plurality of ground stations as a signal from each of the ground stations becomes detectable onboard the aircraft, while the aircraft is in communication with an active ground station. A position of the aircraft is determined each time a signal quality from one of the ground stations reaches a predetermined threshold indicating that the signal quality is suitable for handoff. A set of ground stations potentially suitable for handoff is identified based on their signal quality data when an insufficient signal quality of the active ground station is detected. The set of potentially suitable ground stations is evaluated based on their position and signal quality, and a trajectory or speed vector of the aircraft, to determine an optimal ground station for handoff. A handoff request is then transmitted to the optimal ground station.
