摘　　要：在GPS测量工作中,经常需将测量数据进行实时的传输和处理。然而,GPS测量数据的实时处理是以其正确解码为前提的。在分析串口通讯中数据传统解码算法的基础上,提出了一种直接基于字节数据的实用算法。通过对Ashtech UZ-12型GPS接收机实时传输数据解码试验,证明此算法是一种简单、高效、易于通过编程实现的GPS数据解码算法。Real time communicating and processing of surveying data is often needed in GPS survey. However, the processing of GPS surveying data is based on its correct decoding. By analyzing the traditional decoding algorithm in port communication, this paper presents a practical algorithm which directly based on the binary data. After decoding the real time communication data of Ashteeh UZ- 12 GPS, it proves that this method is effective, simple and easy to realize the GPS data decoding by programming.
