Abstract
A system and method operate to leverage high assurance positioning systems to determine a hybrid deviation from an expected position, altitude, and path to generate a lateral and vertical signal indicating deviation from a desired position. As a filtered or alternative to conventional precision landing systems, the hybrid positioning system receives sensor data from a plurality of sensors and compares the received sensor data to known values to determine a deviation of position and trajectory. Extending the capability of existing auto-land systems, relative-to-runway sensors and/or filtered high assurance hybrid solutions are employed as an alternative to conventional precision landing systems. The sensors provide position data that is compared to an expected position and path to provide deviations in lateral, vertical, and speed augmenting traditional RF-based systems. The result includes a system capability for all weather landing leveraging traditional flight control systems to extend capabilities at all airports.
