GPS无线电掩星技术监测地球大气关键技术

Key Techniques for Terrestrial Atmosphere Monitor via GPS Radio Occultation

介绍了国内外GPS无线电掩星技术研究进展。针对国内无线电掩星研究现状,从工程化角度出发,分析了国内实施该技术可能面临的多方面制约因素,包括:GPS接收机;星上存储介质和高速数据传输;星载接收机精密定轨;数据同化;星座卫星组网等。

Progresses abroad and at home in GPS radio occultation technique are briefly introduced. As far as domestic studies of this technique are concerned, the constraining factors for China to implement this technique are analyzed from the engineering point of view. Difficulties include the followings： highly dynamic GPS receiving equipments, onboard media for massive storage, high speed data transfer, precise orbit determination of onboard GPS receiver, data assimilation, satellite constellating and so forth.
