摘要
利用GDOP定义,提出了最优定位星座的问题。为选择合适的星座,基于m序列设计了组合计数算法,并针对四星、五星以及所有可见星定位算法分别计算了GDOP。对不同定位星数的GDOP变化规律进行了分析、总结和归纳,最后给出了结论。
Based upon the definition of GDOP,the optimum positioning constellation is proposed. For further consideration,m sequence based combinatorial counting algorithm is developed,and GDOP factors are for 4 and 5 satellite positioning algorithms as well as all in view algorithm. The rules of each GDOP are also analysised and summed up.The conclusion is given at the end.
