Abstract
Space activities and attainability are constrained nowadays due to the high cost of
rocketry employed put payloads in orbit. This study aims to design, analyze and
optimize a network of orbital relay stations that can act as orbital energy accumulators
to support other space missions. The sustainability of such network lies in a balance
between payloads being orbited and deorbited.
To test the viability of the proposed network, simulated missions are implemented in a
programming environment in a way that can reproduce numerically the behaviour of the
network in missions of increasing complexity. The design optimization of such missions
is then performed assisted with a built-in genetic algorithm.
The results gathered prove that the energetic balance can be achieved providing an
operation with minimal degradation. Proper mission design and station orbit spacing
are key in defining suitable design conditions that yield the best case performance and
the genetic algorithm is applicable to reduce the losses in off-design operating conditions.
