| Abstract: | 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 Ashtech UZ-12 GPS,it proves that this method is effective,simple and easy to realize the GPS data decoding by programming. |
| Keywords: | algorithm decode floating point number real time GPS data |
