Abstract
A satellite constellation forming system forms a satellite constellation. The satellite constellation is composed of a satellite group. In the satellite constellation, the satellite group provides a service cooperatively. The satellite constellation has a plurality of orbital planes in which a plurality of satellites fly at the same orbital altitude in each orbital plane. A satellite constellation forming unit forms the satellite constellation in which orbital altitudes of the plurality of orbital planes are mutually different.

A satellite constellation forming system to form a satellite constellation which is composed of a satellite group and in which the satellite group provides a service cooperatively, the satellite constellation having a plurality of orbital planes in which a plurality of satellites fly at a same orbital altitude in each orbital plane, the satellite constellation forming system comprising
- processing circuitry to form the satellite constellation in which orbital altitudes of the plurality of orbital planes are same;
- the plurality of orbital planes exist on mutually different planes;
- a satellite passage time point at which each satellite flying in each of the orbital planes passes an intersection point between orbital planes of the plurality of orbital planes is a multiple of a time point shifting value obtained by dividing a wait time until arrival of a next satellite by the number of orbital planes of the plurality of orbital planes, in the same orbital plane;
- no coincidence of the satellite passage time point occurs at any intersection point of any two orbital planes of the plurality of orbital planes;
- an orbital inclination of each orbital plane of the plurality of orbital planes is approximately 90 degrees;
- and the satellite passage time points at which all satellites in all the orbital planes respectively pass a vicinity of a polar region are spaced at intervals of the time point shifting value.
