摘要
在Visual Basic 6.0环境下,针对NovAtel Propak-V3型GPS接收机进行二次开发再现研究。将己成熟的GPS坐标转换技术与几何学理论、计算机语言结合,对NovAtelGPS接收机所测原始数据进行后处理,并通过VB编辑程序再现接收机的运行轨迹。程序中实现对接收机数据的提取、WGS-84坐标系的转换、单点误差修正、差分误差修正、轨迹模拟、数据存储等功能。程序界面简洁清晰、使用方便,可用于记录车辆行驶轨迹、快速测量道路线形参数。
This paper uses Visual Basic 6.0 programming software to exam Propak-V3 NovAtel GPS receiver＇s function,and developes a secondary research of NovAtelGPS to enhance its measurement accuracy and reproduce its built-in programs.The article combines matured GPS coordinates conversion technology with geometry theory and computer language.Compiled program in this paper has achieved several functions include data extraction,conversion of WGS-84 coordinate system,single point error correction,differential error correction,trajectories simulation,retention of data and so on.Program is designed convenient to use,its interface is simple and clear,and can be used to record car running tracks and to fast measure road linear parameters.
