緒論中國是世界上受氣象災害影響最嚴重的國家之一，氣象災害種類很多、頻率高、強度很大，嚴重威脅了我國人民生命財產(chǎn)的安全，氣象災害給人民造成了巨大的損失。ABSTRACTIIABSTRACTHighaltitude meteorological observation system based on GPS（Global Position System）is the future development trend of highaltitude meteorological observation. To state the growing appetite of meteorological observation, and improve the whole level of meteorological observations, we should focus on developing a new generation of radiosonde systems with improved meteorological sensors, data processing and other key technology, to reach the international adcanced level.The GPS aerological sounding system is prised of GPS radiosonde and ground receivingprocessing system. The role of GPS radiosonde is to measure the GPS, temperature, humidity, pressure and other information in high altitude, and the role of the ground receivingprocessing system is to receive and caculate them. This paper is to study how the ground receiver transmits the receiving PTU and GPSmodule digital signal from GPS radiosonde to the puter, then the puter collectes and calibrates the
