Abstract
A system and related method for validating satellite-based navigation data determines an estimated altitude or position solution based on GPS altitude or position data adjusted with inertial altitude or position data integrated with barometric altitude data corrected for air temperature and latitude. The system may include a vertical monitor for validating the GPS altitude data by comparing the weighted, limited, and integrated estimated altitude solution to the GPS altitude data. The integrated altitude solution may compensate for vertical speed offset. The system may provide secondary altitude monitoring by comparing radar altimeter data to local object data to verify obstacle clearance height. The system may include a lateral monitor for validating GPS lateral position data based on weighting and limiting of altitude sources controlled by a height above threshold estimate from the vertical monitor. Validity information may be presented to the pilot or autopilot.
