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.

Description

technical field [0001] The invention belongs to the technical field of flight navigation, and in particular relates to an atmospheric data and attitude heading reference system for flight navigation. Background technique [0002] At present, the flight navigation methods mainly include radio navigation, platform inertial navigation, strapdown inertial navigation, satellite system navigation, etc. Each navigation method has its own advantages and disadvantages. Radio navigation is susceptible to interference; platform inertial navigation is bulky and expensive, and is not suitable for general navigation; strapdown inertial navigation is moderately priced, but its accuracy is relatively low when used alone; satellite system navigation is limited by terrain and is susceptible to interference. Therefore, it is a trend in the field of navigation to integrate several different navigation methods and learn from each other, and it is also a key technology of general aviation navigat...
