PPP技术在攀枝花—东川幅区域重力调查中的应用

THE APPLICATION OF PPP TECHNIQUE TO REGIONAL GRAVITY SURVEY OF PANZIHUA-DONGCHUAN SHEET

应用GPS精密单点定位(PPP)技术及美国喷气动力实验室网站在线定位系统进行解算,基准站联测及重力测点定位精度完全达到规范要求,比传统GPS测量有明显优势,可在区域重力调查中大力推广。

In the application of GPS precision single point positioning （PPP） technique and the on -line positioning system of US ejection dynamic lab website to the calculation, the precision of base station and gravity surveying point positioning completely meet the requirement of norm, which is evidently superior to the traditional GPS survey, and can be used widely in the regional gravity survey.
