Abstract

The invention discloses a data acquisition system for acquiring inertial navigation data. The data acquisition system for acquiring the inertial navigation data comprises a data transmission device and a data acquisition extension for data transmission with each other, the acquired data is sent to a mobile terminal through wireless communication by the data acquisition extension, a navigation module, a GPS module and a PPC development board are arranged in the data acquisition extension, and the acquired data is sent to the PPC development board via a serial port by the navigation module and the GPS module. Code integration is executed by a GPS data acquisition module in a PPC, and the GPS data acquisition module provides externally an interface for being called by a master control program; the code integration is executed by a navigation data acquisition module in the PPC, and the navigation data acquisition module provides externally an interface for being called by the master control program; the code integration is executed by a data sending module in the PPC, and the data sending module provides externally an interface for being called by the master control program.

Description

technical field [0001] The invention relates to a data acquisition system, in particular to a data acquisition system for acquiring inertial navigation data. Background technique [0002] The inertial navigation system is an autonomous navigation system that does not rely on external information and does not radiate energy to the outside. It has good concealment and is not affected by external electromagnetic interference. In the field of aviation, it is an indispensable navigation system for various aircraft, and its attitude accuracy performance is crucial to aircraft navigation, so the attitude accuracy of the inertial navigation system must be calibrated. Like other airborne equipment, the inertial navigation system must be tested under real flight conditions, so as to provide a technical basis for the design finalization / certification of the new inertial navigation system. However, for a long time, the flight test certification of the inertial navigation system, especia...
