子午工程气象火箭探空仪及其探测结果

摘要

研发了一种采用GPS体制的气象火箭探空仪，此种探空仪采用超小快速响应型珠状负温度系数热敏电阻温度传感器、压阻式硅气压传感器和GPS接收机．与其他类型的气象火箭探空仪相比，具有温度、气压、密度、风场等气象要素测量准确度高，遥测接收设备简单便携，发射前的准备工作简单，系统可靠性高等优势，并在子午工程发射试验中实现成功测试．%A meteorological rocket sonde based on GPS system is developed, which is composed of a microminiature bead form thermistor temperature sensor with rapid response and negative temperature coefficient, a piezoresistive silicon pressure transducer and a GPS-Receiver. Compared with meteorological rocket sondes flight before, this new sonde can make higher accuracy measurement of meteorological parameters on temperature, pressure, density and wind field, and its telemetry receiving equipment is more portable. Besides, simple prelaunch preparation work and high system reliability are two other advantages of it. The launching test of the sonde has been successfully conducted in the Meridian Project, and satisfactory detection results have been obtained.
