摘要 为了消除定位过程中误差带来的影响,介绍了高精度GPS差分定位技术的基本原理、定位精度、系统类型和处理方式,在此基础上分别对位置差分、伪距差分、相位平滑伪距差分和载波相位差分四种不同高精度GPS差分定位技术的原理和算法进行了详细介绍,并进一步总结分析其优缺点,提出了今后将不同高精度GPS差分定位技术融入手机定位的研究方向。 In order to eliminate the impact of positioning error, this paper introduces the principle of high-precision GPS differential positioning technology, as well as its positioning accuracy, system type and processing mode. Based on analyses above, the principles and algorithms of tbur different types of high-precision GPS differential positioning technology are elaborated, including position differential, pseudo-range differential, phase smoothing pseudo-range differential and carrier phase differential. Their advantages and disadvantages are summarized analyzed in detail. In the future, it is promising that different high-precision GPS differential positioning technology would be integrated into positioning of mobile phone.
