3. Ideally, one would like to have as few tracking passes from LiAISON and ground tracking as possible to obtain an accurate solution. There exists an area of this analysis from which relatively accurate estimates can be obtained using very few tracking passes. The tracking schedules for this region are 28-30 hour gaps for LiAISON and 48-56 hour gaps for ground tracking. In this region the halo orbiter’s uncertainty is around 110 meters while the GEO accuracy is about 35 meters. With very few measurements from both LiAISON and ground tracking, reasonable estimates of both satellites states are obtained.
