A satellite constellation is a group of artificial satellites working together as a system. Unlike a single satellite, a constellation can provide permanent global or near-global coverage, such that at any time everywhere on Earth at least one satellite is visible.

2022年10月28日 · A satellite constellation (or swarm) is a network of identical or similar-type artificial units with the same purpose and shared control. Such groups communicate to worldwide-located ground stations and sometimes are inter-connected.

Satellite constellation design under orbital perturbations. Any satellite's orbit is going to be constantly affected by orbital perturbations during its mission life. Therefore, it is in our interest to guarantee the stability of the satellite formation both in the short and long terms.

three satellite constellation design algorithms. These algorithms are: an inclined, symmetric constellation algorithm (often known as Walker constellations), a polar, non-symmetric constellation algorithm, and an adaptive random search algorithm used for satellite constellation design optimization. These three algorithms address various needs ...

2024年1月3日 · Satellite constellations design methods have begun to address optimal large-scale mega-satellite constellations. Many of the optimization techniques used for optimal satellite constellation design struggle when designing satellite constellations with …

In this article, we discuss a new constellation design (patent pending), which we call a Waves constellation, developed by the Johns Hopkins University Applied Physics Laboratory (APL) to provide optimal coverage in a given latitude band.

2017年5月31日 · A study on Simulated Annealing and GA approaches to satellite constellation design for coverage of a limited latitude region was conducted by Crossley and Williams , where both methods outperformed the conventional Walker approach at low Earth central angles.

2016年8月1日 · To implement the reconfiguration phase of the satellite constellation arrangement at minimal cost, the hybrid Invasive Weed Optimization/Particle Swarm Optimization (IWO/PSO) algorithm is used to design sub-optimal transfer orbits for the satellites existing in …

2019年11月20日 · Explain, how a the design process incorporates the full life cyle a complete satellite constellation.
