Analysis and Simulation on Minimum Value of GDOP in Satellite Navigation

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 t...

Zusammenfassung: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.
