摘要
介绍一种低成本的差分全球定位系统(价格在200英镑以内),系统利用ATmel91EB55测试板及AT91M55800A处理器,建立了一种基于嵌入式设备的伪距差分GPS系统的设计方案,在满足实时性和稳定性的基础上,实验结果可以使定位精度提高至5 m以内。
A low cost differential GPS positioning system is introduced. The design schemes of the pseudo-range differential GPS positioning system is based on the embedded device by using the microcontroller ATglM55800A and evaluation kit ATglEB55. The result proves that the positioning precision is improved to less than 5 meters with satisfied real-time capability.
