摘要： 针对传统的单点定位方法无法满足应用需求日益提高的实时定位精度问题,提出一种新的广域实时亚米级单点定位算法。基于单频接收机提供的卫星原始观测值,通过网络获得由国际GPS服务(international GPS service, IGS)播发的GNSS卫星精密轨道和钟差以及格网电离层改正数据,在终端嵌入式软件或APP软件程序中,通过载波平滑伪距的定位模型进行定位解算得到用户精确位置。大量试验结果统计分析表明:该算法在全天候任意时段内均可实现平面方向优于0.8 m、高程方向优于2 m的静态定位精度,以单频接收机的硬件成本,快速收敛实现了实时亚米级定位精度,能够满足大量应用场景对连续稳定可靠的高精度实时定位要求。提出的广域实时亚米级单点定位技术,能够在无需大量建设地基增强基准站的情况下,提供广域范围内大部分应用场景下的实时亚米级高精度位置服务。

Abstract: In order to solve the problem that the traditional single point positioning was unable to meet the increased requirements of real-time positioning accuracy in the applications, a new algorithm of wide area sub-meter single point positioning in real-time was proposed. The embedded software within hardware or the APP software to get the precise location by using the positioning model of carrier smoothed pseudorange, it obtained the corrections of precision orbit and clock errors and ionospheric grid for GNSS satellites which was broadcast by IGS through the network, and it was based on the raw observations of satellites which was provided by single-frequency GNSS receiver. A large number of experimental results showed that this algorithm could be achieved better than 0.8 meter positioning accuracy on the planar direction, and better than 2 meter positioning accuracy on the elevation direction, using the same hardware cost as single-frequency receiver to achieved sub-meter positioning accuracy in real time and with fast convergence. This algorithm could provide real-time sub-meter high-accuracy location services within the wide area for most applications, without to build a large number of the ground augmentation base stations.

Key words: state space representation correction, real time differential positioning, real time single point positioning, carrier phase smoothing pseudorange, wide area sub-meter positioning
