Abstract
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 four 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.关键词
