基于GNSS的车辆协同定位定向设计

全球卫星导航定位系统的高精度载波相位差分技术已经广泛的应用在很多领域。本文介绍了载波相位差分定位技术应用在车辆定位定向中的软件与硬件实现方法。硬件主要包括整个平台的组成与搭建；软件主要以单差正交模型为主，利用迭代的方法综合多历元数据进行载波相位浮点解的计算。对该方法进行实际测试，结果精度可达厘米级。

Design of Vehicle Cooperative Location Based on GNSS

High-precision global navigation satellite carrier phase difference positioning system technology has been widely applied in many fields. This paper introduces the software and hardware implementation method of carrier phase difference location technology which has been applied in military vehicle. Hardware mainly includes the composition and construction of the whole platform, the software is mainly based on single difference which uses orthogonal transformations and iterative method to calculate carrier phase float solution. The method was actually tested, up to centimeters.
