摘要
局域增强系统由地面子系统和机载子系统两部分组成。地面子系统计算卫星的伪距校正量等差分数据，并将这些数据发送给机载子系统。机载子系统利用这些差分数据，精确地完成位置的解算，达到改善定位精度的目的。本文描述了在局域增强系统中进行伪距差分定位的方法。
The Local Area Augmentation System consists of the ground subsystem and the airborne subsystem. The ground subsystem calculates satellites＇ pseudorange differential corrections datum, and the datum are transmitted to the airborne subsystem. The airborne subsystem accurately completes the solution of position utilizing the differential datum, to achieve the purpose of improving positioning precision. The article describes detailedly the method of the pseudorange differential positioning on Local Area Augmentation System.
