摘　　要：介绍了一种新型微型飞行器高度计的设计技术,主要是利用微型数字压力传感器和PIC单片机串行通信,读取传感器中压力、温度值及补偿参数,用软件进行温度补偿和高度计算;经试验室测试,其相对高度误差<±3m。且该高度计具有体积小、重量轻、功耗低、工作可靠等特点。A new design technology of altimeter of micro air vehicle is introduced. Using micro digital pressure sensor and microcontroller chip PIC to make series communication, the pressure, temperature and compensation parameters from the sensor are read out, compensation of temperature and calculation of height are carried out with the software. The test in the laboratory shows that its error is less than ±3 m. And the altimeter has many merits such as small volume, light weight, low power consumption, and high reliability etc.
