Paper Abstract

Space mapping satellites play an increasingly important role in Space mapping satellites play an increasingly important role in mapping and mapping. The positioning accuracy of mapping satellites is the core and key index for evaluating the performance of Surveying and mapping. At present, it has developed to the precision of the meter level. Therefore, in the design process of Surveying and mapping camera, it is not only necessary to ensure that the image has good MTF, signal to noise ratio, dynamic range and other basic radiation characteristics, but also need to focus on the high precision calibration of the interior orientation elements of optical system distortion, optical axis, focal distance and other questions of orbit stability.

In 2012 and 2016, China successfully launched ZY-3 (01/02) satellites, with a three-line-arrays camera and a multispectral camera. It is mainly used for the production of basic geographic information products of 1:50000 scale, and modification and updating of 1:25000 and larger scale topographic maps in China. The satellites have achieved good application results. Based on these experiences, driven by higher precision surveying and mapping requirements, as the main development and research organization of the Chinese space optical remote sensing camera, BISME has carried out a serial of research in the overall design of the space optical surveying camera. This paper gives some own views about the research for discussion and exchange.
