This article is a survey paper on solving spacecraft trajectory optimization problems. The
solving process is decomposed into four key steps of mathematical modeling of the problem …

Designing satellite constellations often requires consideration of many factors including
mission requirements, program budget, and technological capabilities. An abundant amount …

THE optimization of interplanetary trajectories continues to generate a great deal of interest
[1, 2]. In interplanetary missions, it is usually desired to send a spacecraft to rendezvous with …

This study proposed a satellite constellation method to cluster targets using machine
learning and achieve the desired revisit performance for each target in an area of interest …

A novel method for designing repeat ground track orbits based on the Number Theory is
presented. The desired revisit time, tilt capacity, payload swath width, and side-lap are …

This research proposes a low-inclined orbit concept and design for the Internet-of-Things
(IoT) using lean satellite standards in near-equatorial regions. The study aims to evaluate …

This article presents an optimization method for satellite constellations oriented toward
observation targets in an area of interest. Specifically, the satellite constellation is optimized …

For operationally responsive space missions, traditional orbit design problems are only for a
single type of targets, ie, only ground targets or only space targets. This paper studies the …

A novel self-adaptive variable-size multi-objective differential evolution algorithm is
presented to find the best reconfiguration of existing on-orbit satellites for some particular …

IN INTERPLANETARY space missions, a spacecraft usually rendezvous with one or more
planet (s) or asteroid (s). It is almost always desired to optimize the spacecraft trajectory so …
