Research and Realization of a Altitude Location Method for Small UAV
Hailong Pei · Automation and Instrumentation · 2010
General framework and autonomous flight strategy of a small UAV is presented briefly,then focuses on the realization of the hardware design and software algorithm of measuring and control of altitude.To get the precise attitude control and trajectory tracking,the data of multi-sensor composed of GPS、sonar and pressure sensor is processed through some data fusion algorithm is applied to GPS/INS integrated navigation system.Actual flight data shows that the flight control system design of hardware and realization of software algorithm cooperated perfectly and achieve the expected result.
