Abstract

The invention discloses a data acquisition system capable of acquiring inertial navigation data. According to the data acquisition system, data transmission is carried out between data transmission equipment and a data acquisition extension set; and the data acquisition extension set sends the collected data to a mobile terminal through wireless communication. An inertial navigation module, a GPSmodule and a PPC development board are arranged in the data acquisition extension set; and the inertial navigation module and the GPS module send the collected data to the PPC development board through serial ports. The GPS data acquisition module performs code integration in the PPC; interfaces are provided externally for invoking by a main control program. The inertial navigation data acquisition module performs code integration in the PPC and uses the same interface with the external space for invoking by the main control program. A data sending module performs code integration in the PPC and provides an interface externally invoking by the main control program.

Description

technical field [0001] The invention relates to a data collection system, in particular to a collection system for collecting 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, especially th...
