北斗系统在港口定位中的应用

Application of Positioning Method of Beidou System in Port

为提高北斗系统在港口定位中的精度,提出利用北斗多参考站系统进行相位平滑伪距差分定位的方法。介绍伪距差分数学模型和多参考站综合伪距改正,并以实例说明。实验表明,该方法能够将定位精度提高到分米级,明显优于北斗伪距单点定位。

In order to raise precision of Beidou system in positioning in port, the phase smoothing pseudo-range differential positioning based on multi-reference stations has been developed. The pseudo-range methmatics model and comprehensive pseudo-range correction of multi-reference stations are introduced, and example is taken to illustrate the principle. It is indicated by test that the location precision could be enhanced to decimeter level by this method, which is superior to method of preudo-range single point positioning.
