Resümee

This paper is targeted at the key and different technology appeared in system design and manufacture of high resolution stereo mapping satellite. On the basis of analyzing the development history and technical characteristic of mapping satellite both at home and abroad，and according to achievement of the high image positioning accuracy which is the key design of the mapping satellite，the paper shows the result of research about the design of high resolution stereo mapping satellite，such as design constraints，choose of the mapping system，and key and difficult points of design for both payload and platform products.The paper analyses the different special technique and engineering constraints of three line array camera system, two line array camera system, and single line array camera system. Since the satellite with single line array camera system can’t fulfilling large area’ mapping requirement, and it also have difficult on getting steady performance, the two or three line array camera systems are chosen by different contries’ special satellites with main task of mapping the earth. Considering the carrying capacity of satellite platform, to get high precision and high resolution stereo image, the two line array camera system is thought to be the best choice at this time. The paper gives out the design elements and achievement methods for high image positioning accuracy, such as orbit measurement, attitude measure and control, time measure and synchronization, camera inner elements, and it also gives out the detail about the influence of every element.Then the paper gives the design of the GF-7 satellite which is designed according to two line array camera system, and is the first stereo mapping satellite with sub-meter level resolution of China. After gives out the performance requirements to the satellite, and its major components also was shown. The paper shows the technical innovation of satellite which is to fulfil the requirement of satellite mapping task, such as new mapping system with both active and passive imaging, high resolution mapping camera, new laser altimeter, high precision attitude measure and control system, and high speed date transmission ability.At last，the image quality test results about GF-7 satellite images are given out by difficult consumers, including: Ministry of Natural Resources, Ministry of Housing and Urban-Rural Development, and National Bureau of Statistics. The test results show that due to the research results which given out by this paper, GF-7 satellite works very well in orbit, the actual image positioning accuracy is better than initial requirement. The satellite image can be used to produce 1∶10000 scale map, make investigation to city’s three dimensional transportation, measure the highway’s altitude, and check the variety of agricultural land. The satellite performance is better than the task’s requirement, and reaches the world leading level. The research results in this paper can be a strong reference to the design of larger scale stereo mapping satellite in the future.
