Abstract: The invention belongs to the technical field of flight navigation and in particular relates to an air data and gesture heading reference system for flight navigation. The system solves the problems in the conventional flight navigation mode. The system comprises a strapdown type inertial gesture sensor, a global positioning system (GPS) system receiving module, an air data sensor, a magnetic sensor, a temperature sensor and a signal processing module, wherein the input ends and the output ends of the inertial gesture sensor, the GPS receiving module and the air data sensor are connected with the signal processing module; and the output ends of the magnetic sensors and the temperature sensors are connected with the signal processing module. The system has the benefits that the gesture sensor has autonomy and can make up the defects that the GPS is limited by the topography and susceptible to interference; the GPS has real-time property and can make up the defect that the error of the gesture sensor is accumulated along with the time; the air data sensor provides high-precision air data and can be used for correcting the gesture information of the system; and the system has small size and light weight.
