多基准站式快速静态GPS测量及其应用

The Application of Fast Static GPS Measurement with Multiple Reference Stations

静态GPS测量作为一种经典的测量方式广泛用于高精度监测以及建立各种类型和精度的测量控制网。为确定两点之间的基线向量,较为普遍的作业模式主要有静态相对定位,快速静态相对定位,准动态相对定位和动态相对定位等。本文介绍的多基站式快速静态GPS测量方法,由各个基准站同步不间断的观测提供高精度、高可靠性的骨架基线,而快速静态测量流动站与、多个基准站之间构成同步向量,无需考虑各个观测点之间的网形分布。

Static GPS measurements as a classical measurement method is widely used in high-precision geodetic control measurement,established of various precision control network. . To determine the baseline vector between two points,there are a variety of GPS measurement mode,such as static relative positioning,fast static relative positioning,rel-ative positioning and dynamic quasi-dynamic relative positioning. Multi-station-style fast static GPS measurement meth-od is described in this article,synchronous continuous observation by each base station to provide high-precision,high re-liability skeleton baseline,and fast static measurement between the rover and the coincident vectors,multiple base sta-tions,without regard to net-shaped distribution between each observation point.
