  • Patent number: 10512021
    Abstract: A system including a constellation of satellites in Low Earth Orbit and a plurality of ground stations to enable continuous communication for other geocentric, non-geosynchronous spacecraft. Network latency, Doppler effects, and router handover time are minimized through selection of orbital parameters for the satellite constellation and locations of ground stations. A plurality of polar or near polar orbit planes is presented at equally spaced right ascension of the ascending node (RAAN), in an alternative ascending-descending pattern. Inter-satellite communication is performed in-plane to relay data to a ground station, and out-of-plane or in-plane to communicate with another satellite that is not a member of the constellation. The number and location of ground stations is selected based on the number of small satellites and orbital planes in order to maintain continuous communications.
