Based On The Technology Of Gps Single Baseline Measurement Posture

For the field of the measurement and control system, the attitude measurement of plat is the very important embranchment all along. But the conventional attitude measurement equipment is too expensive to be put into practice. So the technology that measure the plat attitude based on GPS emerged as the time required. And with the rapid development of DSP technology, it would become true that acquire the real-time attitude parameters. This paper investigates the single-baseline attitude determination technology which is based on GPS and designs the related DSP hardware system, the result is satisfying.Firstly, this paper introduces the GPS, the position theory and the related position technology systemically, analyzes GPS measurement model in detail.Then, this paper gives the general design of the single-baseline attitude determination technology and divides the whole system into four modules. By the way, it also introduces the way that how to process the raw data from the GPS receiver at length.In the third part of the paper, the implement of absolute position is introduced in detail. Some factors that would influence the accuracy of orientation were analyzed in particular, and the paper gives the related way that reduced these influences. The fourth part of the paper discusses the way that how to compute the ambiguity quickly and correctly. In this part, a algorithm utilizing the Z-transformation augmented FASF(Fast Ambiguity Search Filter) was introduced. The algorithm can compute the most of ambiguity in a very short time. It is very useful to compute the real-time attitude parameters.Finally, the paper gave the result of simulation and hardware design. By comparing and analyzing the result, the feasibility of the design is contenting.In short, the paper introduces the design and the implement of the single-baseline attitude determination system from the system to module in detail. The last result is satisfying.
