Optimization of relative orbit transfers via particle swarm and primer vector theory
… are used in order to create the solution vectors for the particle swarm, and the Clohessy-Wiltshire-Hill equations are used to define the motion of the satellites. These trajectories are then analyzed according to primer vector theory, in order to check the optimality of the trajectories …

Optimal orbit transfers for satellite formation flying applications
… an analytic linearization method, termed the “primer vector approximation method,” for solving nonlinear continuous-thrust trajectory optimization problems.

Optimal cooperative power-limited rendezvous
… Solutions obtained are checked against the primer vector necessary conditions for optimality. The optimal solutions depend in a complicated way on the power-to-mass ratios of the two spacecraft, the initial conditions, and the specified transfer time. Propellant and terminal orbit …

Optimal cooperative time-fixed impulsive rendezvous
… uses an analytical gradient developed using primer vector theory and a new solution for the optimal terminal (rendezvous) maneuver. Results are presented for a large number of cases in which the allotted time for rendezvous and other problem parameters including initial relative position, …

Optimal, impulsive, direct ascent, time-fixed orbital interception
… necessary conditions expressed in terms of the primer vector. The vehicle is initially at rest on the surface of a spherical planet and the target is assumed to be in a circular, equatorial orbit around the planet. Results are presented and compared for two planetary models: a non-rotating …

Spacecraft trajectory optimization using many embedded Lambert problems
… trajectory optimization, extensively used in primer vector theory, flyby-tour design, direct impulsive-maneuver optimization, and more. Lack of fast and accurate BVP solvers has prevented the use of the EBVP technique on problems with more than dozens of segments. For the two-body problem, a …
