摘要

当使用来自全球定位系统的信号来精确估计车辆的航向时，主要的挑战是找到载波相位测量包含的整数模糊性。利用天线之间的已知距离，这一过程可能会得到改进的结果，如果仔细选择可观测数据，即每颗卫星的测量结果，甚至可以进一步增强。本文研究了观测数对航向估计解的精度和稳定性的总体影响。所提出的结论为如何选择哪些观测值对解决方案最有利提供了明确的指导。

Impact of satellite coverage in single-frequency precise heading determination

When using the signal from the Global Positioning System for precise estimation of the heading of a vehicle, the main challenge is finding the integer ambiguities that the carrier phase measurements contain. Using the known distance between the antennas, this process may return improved results, which can be even further enhanced if careful selection of observable data, the measurement from each satellite, is applied. This paper presents a study of the overall influence of the number of used observables in the precision and stability of the heading estimation solution. The presented conclusions provide clear guidance on how to elect which observables are the most beneficial to the solution.
