Abstract

The present invention provides an inertial / satellite integrated navigation demonstration verification system for data reproduction. The inertial / satellite integrated navigation demonstration verification system comprises: a data transmitting and receiving module for reading IMU data and GPS data, outputting an analog second pulse, and then transmitting the IMU data and the GPS data to a navigation computer module; the navigation computer module for receiving the IMU data and the GPS data transmitted by the data transmitting and receiving module, caching, and performing data processing by using a master-slave DSP working mode; and a data displaying module for displaying the data processed by the navigation computer module, dynamically reproducing the movement state in an offline manner, and evaluating the precision of a new navigation demonstration verification algorithm. With the inertial / satellite integrated navigation demonstration verification system of the present invention, the real IMU and GPS receivers are replaced with the data transmitting and receiving module so as to the reduce the physical loss of the system and improve the service life, and the system movement state is dynamically reproduced in the offline manner so as to demonstrate and verify the new navigation algorithm.

Description

technical field [0001] The invention relates to the technical field of integrated navigation, and can be applied to POS (Position and Orientation System, position and attitude measurement system) demonstration and verification experiments, in particular to an inertial / satellite integrated navigation demonstration verification system for data reproduction. Background technique [0002] In the inertial / satellite integrated navigation system, POS is the key general equipment essential for the aviation earth observation system to complete the surveying and mapping tasks, and can provide position, velocity and attitude references for various observation loads. It consists of four parts: a high-precision inertial measurement unit (Inertial Measurement Unit, IMU), a global positioning system (Global Positioning System, GPS), a POS computer (POS Computer System, PCS), and POS post-processing software. The movement of the sensitive carrier of the inertial measurement unit converts th...
