Abstract
The construction of a navigation system plays an important role in the development of national politics, economy and military affairs. Nowadays, the Beidou navigation system is facing a transition period from the regional navigation system to the global one. For the global constellation, the system performance will not be seriously degraded when one or two satellites are invalid, but it is out of case for the regional constellation, which usually has fewer satellites and less redundancy. This paper deals with this problem of hybrid constellations and analyzes the influence of the disabled satellites on the system. With hybrid constellations and simulation methods designed, the influence of invalid satellites on the navigation system is fully investigated.
