GPS/BD双定位定向系统的研制及实现

Research and Realization of GPS/BD Double Positioning and Orientation System

本文详细介绍了GPS/BD双定位定向系统的软、硬件设计方案。接着对开发该系统的关键技术,包括投影变换、数据通讯和求解整周模糊度进行了较深入地研究。最后,通过系统实际测试,得出部分重要结论,表明该系统的研制是非常成功的,不仅在GPS测姿领域具有广阔的应用前景,而且当GPS无法正常工作时,BD仍可完成定位任务。可见,BD应用将创造更大的经济和社会价值。

Firstly, both the software and the hardware design of GPS/BD double positioning and orientation system are introduced in this paper. Then, the critical technologies of developing the system, including projection transformation, data communication and ambiguity solving are carefully researched. Finally, some important conclusions which are drawn by testing the practical system, demonstrate that this system can work well. And its application is not only in the field of developing GPS attitude determination system, but also the BD still can finish positioning task when GPS can not work as usual. It is obvious that more economic and social value should be obtained because of BD development and spplication.
