Abstract
This paper introduces a height precision acquisition system based on the DSP and BMP085 digital pressure sensor in UAV. And it analyses the practical results of measurement and analysis data of the system , to achieve height measurement and to transmit data. The paper sets focus on how to design and achieve the soft and hardware of the height collect sides , and the essentials of hardware and software design are expatiated. The system has the characteristics of low power consumption , simple construction, high precision, strong anti-jamming, as well as reducing impacts of environment. The measuring system uses a Kalman filter algorithm to amend the measurement data to calculate the relative height more accurately.关键词
