传统的单点实时定位简单灵活,但精度低,一般的差分定位需要布设基站,作用距离短。广域精密单点定位技术恰好集成了普通单点定位和差分定位的优点,克服了各自的缺点。通过星基增强系统的卫星信号代替地面GPS基准站的差分信号的方法进行海上探测作业,提高了作业效率,进一步证实了此方法的有效性。

The traditional point positioning method is simple and flexible, but with low precision. The normal Differential Global Positioning System (DGPS) needs Base Station, so application range is small. Wide area difference Precise Positioning combines the merits of theirs, overcomes the defects of methods. One method was proposed, instead of the differential signal from GPS base station by the non--commercial satellite signal from WAD SBAS. The method can satisfy the requirement of accuracy and it makes offshore exploration even more quickly convenient .
