Air data acquisition is the main factors affect the free flight control, in order to realize the sampling of the signal source, according to the measurement principle of the air data altitude and airspeed, choose the simple small pilot tube as the sampling path, using chip level dynamic pressure and static pressure sensor as signal source, the design of atmospheric FPGA data acquisition system based on the algorithm, and the realization of the data processing in DSP processor. Finally through the show in a small unmanned flight test results on the UAV, atmospheric data acquisition system can achieve a high degree of access to space velocity and pressure.
