Abstract:

Aerospace surveying and mapping has become the main method of global earth observation. It can be divided into the geodetic observation satellites and the topographic surveying satellites according to the disciplines. In this paper, the geodetic satellites and photographic satellites are introduced respectively. Then, the existing problems in Chinese earth observation satellites are analyzed, and the comprehensive satellite with integrated payloads, the intensive microsatellite constellation and the intelligent observation satellite are proposed as three different development ideas for the future earth observation satellites. The possibility of the three ideas is discussed in detail, as well as the related key technologies.

Key words: aerospace surveying and mapping; gravity satellite; magnetic satellite; optical mapping satellite; microwave mapping satellite; microsatellite networking; intelligent satellite observation
