Primer vector theory, in combination with a parameter optimization algorith
m, is used to compute the optimal transfer of n spacecraft from an initial
parking orbit to a final operational orbit with the added constraint that a
ll spacecraft an: injected from the parking orbit on one upper-stage booste
r and that all are required to be spaced along the final orbit according to
some prescribed, but otherwise arbitrary, spacing constraint between indiv
idual spacecraft. Two particular cases of the problem, known as the weak- a
nd the strong-booster cases, are examined, In the weak-booster case, the bo
oster provides the departure maneuver from parking orbit, but because of a
booster propellent constraint, its trajectory does not reach the final orbi
t, requiring that all spacecraft make at least two maneuvers to complete th
e transfer. For the strong-booster case, the booster departure maneuver is
unconstrained in magnitude, implying that at least one of the spacecraft ca
n complete the transfer with a single maneuver because the transfer traject
ory ran reach the final orbit. The solution is formulated for a general for
ce field, and examples are given for a three-spacecraft constellation trans
fer in the restricted three-body problem force-field model.
