On the scalability of battery‐aware contact plan design for LEO satellite constellations
International Journal of Satellite Communications and Networking, 2020SummarySize and weight limitations of low‐Earth orbit (LEO) small satellites make their operation rest on a fine balance between solar power infeed and power demands of supporting communication technologies, buffered by on‐board battery storage. As a result, the problem of planning battery‐powered intersatellite communication is a very difficult one ...

Design and simulation for hybrid LEO communication and navigation constellation
2016 IEEE Chinese Guidance, Navigation and Control Conference (CGNCC), 2016LEO satellite communication systems and LEO satellite navigation systems are imperative in various fields. Therefore, a method to design hybrid LEO constellation for communication and strengthen the capability of navigation is proposed in this paper, which takes coverage capability and precession into consideration. Firstly, the methods of selection of

Design of Mega-Constellations of LEO Satellites for Positioning
2018With the huge potential of the GNSS market and thousands of LEO satellites in space in the future, a novel way is to use these LEO mega-constellations for positioning. In order to fulfil this purpose, the first step is to build a constellation that could be used for both communication and positioning.

LEO constellation design methodology for observing multi-targets
Astrodynamics, 2018This paper is based on the second problem of the 8th China Space Trajectory Design Competition (CTOC8). The background is LEO constellation design strategy for monitoring discrete multi-targets with small satellite under J2 model. The difficulty is that the small satellite is equipped with low-cost cameras with limited coverage ability and the targets ...

Design and Optimization of an Autonomous Constellation of Small-satellites for LEO and Beyond
2022The speedy data reception with useful applications such as disaster management remains to be need of the hour. This paper addresses the major concerns relating to deployment and control of the larger small satellite (mainly cubesats) constellations in LEO by determining their relative position and velocity errors under certain acceptable limits with ...

Constellation Design and Performance Simulation of LEO Satellite Communication System
2011LEO satellite communication weighs more and more in communication system now and future. Since different types of constellations have rather different performances in coverage ability and inter-satellite link (ISL) building conditions, a polar and an inclined circular low orbit constellation were designed in this work.

Orbital design of LEO navigation constellations and assessment of their augmentation to BDS
Advances in Space Research, 2020Abstract Navigation augmentation based on Low Earth Orbit (LEO) satellites has become a hot topic in recent years. The orbital design of LEO augmentation constellations and the analysis of their performance are essential issues for the development of LEO augmentation systems.

Design of LEO Hybrid Constellation for Intensive Observation in Specific Area
2019 Chinese Control Conference (CCC), 2019At present, Earth observation satellites mainly rely on the ground stations to upload mission instructions, and only use their own payloads to complete data acquisition. There is no cooperation based on real-time collected information between satellites, thus the system response ability is insufficient.

Tentative design of SBSS constellations for LEO debris catalog maintenance
Acta Astronautica, 2019Abstract This paper proposes three Sun-Synchronous Orbit (SSO) Space-Based Space Surveillance (SBSS) optical constellations with the intention of building up and maintaining a catalog of 200,000 LEO space debris. The three constellations, namely CON.1, CON.2 and CON.3, are Walker analogs whose notations are “98.7°:12/4/1”, “98.7°:12/6/1”, and “98.7 ...
