Mapping Satellite-1

designed and developed with the heritage of small satellite CAST 2000 by DFH Satellite Co.LTD

is the first new-generation transmission type photogrammetric satellite of China.Its photogrammetric positioning and mapping system uses LMCCD（Line Matrix Charge Coupled Device）surveying and mapping structure

consisting of three independent panchromatic mapping CCD cameras for forward

nadir and backward looking

three star sensors and one GPS receivers.On the focal plane of the nadir-looking camera

beside one linear array CCD

there are four area array CCDs to improve elevation accuracy.The nominal B/H ratio for stereo is 1.0.By a optical bench of high strength

high rigidity

high stability

the three mapping cameras

three star sensors and a multispectral CCD camera are integrated together as an organic whole

satisfying well high precision and high stability missions requirements of the geometrical angle relations between the cameras.In-flight test results show that the photogrammetric positioning accuracy is better than mission requirements

and Mapping Satellite-1 satisfies global mapping requirements of 1:50000 scale without ground control points.The General design

technical features

course of development and in-flight images of Mapping Satellite-1 are mainly presented in this article

especially the technical characteristics and the application perspective are emphatically described in order for different users to utilize all kinds of products of the satellite better

improving its application efficiency.
