摘要

目前国内外相关文献在推导GDOP理论最小值时没有考虑接收机的可观测范围,故在现实中是无法达到的。在限制卫星高度截止角大于零的条件下,重新推导了GDOP的理论最小值,并提出相应的求解方法,给出GDOP值达到最小时卫星的空间几何分布情况;最后通过算例验证本文推导得到的GDOP理论最小值的正确性。

Abstract

The computation of minimum GDOP can't be acquired in previous researches, because receiver only receives signal when satellite is above the ground level. In this paper, the equation of GDOP minimum value was again deduced with the constraint of satellites above zero degree elevation, a method to get the minimum of GDOP was given and the user/satellite geometry was considered. Finally, computation indicated the new algorithm on the minimum of GDOP is effective and useful.

Key words： satellite navigation; minimum value of GDOP; number of visible satellite; matrix analysis
