摘要
通过GDOP(几何精度因子)来研究伪卫星定位的精度分布情况。首先提出一种GDOP的工程实用算法,然后研究伪卫星的可能布局方案以及伪卫星布局地区以外的延伸地区GDOP的情况,结合工程实际,进行大量的仿真试验,给出合理的伪卫星布局方案。仿真验证表明,GDOP算法及伪卫星布局方案的选择可以为工程应用提供良好的理论指导作用。
GDOP(geometric dilution of precision)is used to research the accuracy distribution of the pseudo- lite. Firstly, a practical arithmetic in engineering of GDOP is proposed. Then the possibility distribution scenario and the GDOP of the extend region are researched. Finally, based on the engineering, combined with the simulation the rational distribution scenario is given. The simulation results show that the arithmetic of GDOP and the selective of the pseudolite distribution scenario could play a theory guiding to engineering.
