Satellite constellation design of on-orbit servicing space system for Globalstar satellites

The ballistic problem of on-orbit space serving system configuration design for active Globalstar satellites is considered. These satellites are moving in orbits with close altitudes and inclinations but with significant difference in longitude of ascending node (more than 10 degrees). The onorbit space servicing system is a system of base orbital stations for servicing the given array of the satellites using the detachable orbital modules. The noted acoplanarity leads to high expenses of the total relative velocity (fuel) required for inter-orbit flights to serving satellites. The article provides an example of solving the design problem basing on the developed methodology of optimal serving planning using up-to-date algorithms of estimating energy costs of flights to serving satellites, that significantly decrease flight fuel costs. The problem of configuration design of space serving system as well as the problem of optimal serving planning has been solved basing on the analyzing the deviation map of satellites and orbital stations longitudes of ascending node. It is shown that proposed method allows to define the necessary amount and orbit parameters of orbital stations, the amount of detached orbital modules and total relative velocity, needed to service the given group of spacecraft.
