A method and system for formationfinding and formationkeeping in a constellation of satellites (20) orbiting about a primary body (34) is provided. A set of satellite (20) destination position (22) and time goals is selected corresponding to the satellite\s (20) station in a desired constellation. The satellite (20) senses actual destination arrival positions (32) and times relative to reference positions independent of the constellation and compares these values to values from the set of goals. Corrective maneuvers are selectively implemented responsive...
A method for finding and maintaining a satellite station in a fixed geometry constellation of at least two satellites in inclined, near-circular orbits about a primary body, comprising the steps of: a) selecting constellation values common to each satellite of said constellation indicative of each said satellite\s orbital period, inclination, and nodal regression rate; b) determining a set of nodal arrival longitude and time goals for each satellite based on its station in said constellation; c) measuring actual satellite nodal arrival longitudinal and t...
