This paper is concerned with adapting the IEEE 802.11 protocol for inter-satellite links in distributed satellite formations for rapid response and disaster monitoring from low Earth orbit. Key optimisation approaches such as tuning of the IEEE 802.11 physical layer parameters and enhancing the data link layer are described. Integration of smart antennas with the medium access control protocol is...
In this paper we investigate key IEEE 802.11 optimization techniques with the aim to adapt the commercial-of-the-shelf (COTS) wireless standard for inter-satellite communication in autonomous distributed spacecraft formations. Optimisation approaches such as the tuning of the IEEE 802.11 physical layer parameters and enhancing the data link layer for space applications are described. The integration...
Future spacecraft are envisioned as massively distributed space systems flying in formation. In this paper we present an approach to signal routing over inter-satellite links (ISL) in a network of sub-kilogram satellites using a single-objective optimisation algorithm (SOA) and a multi-objective evolutionary algorithm (MOEA). The IEEE 802.11 protocol is modified for ISL, with a maximum communication...
This paper is concerned with application of standard wireless COTS protocols to space. Suitability of commercially available wireless sensor mote kits for communication inside and between satellites is investigated. Spacecraft applications of motes are being considered and a set of requirements are identified. Selected mote kits are tested under various scenarios complying with spacecraft testing...
Picosatellites are very small satellites with a mass of less than 1 kg. A number of picosatellite projects have been undertaken by University and government research teams. Constellations of picosatellites could prove to be a low-cost and efficient solution to remote sensing in LEO. Reconfiguration and adaptation are capabilities, which are of critical importance to such constellations. A conceptual...
This paper describes key optimization techniques, which are aimed at extending the terrestrial wireless network to space to satisfy the communication needs of autonomous distributed multi-spacecraft constellations. The IEEE 802.11 inter-frame re-definitions for increased range are addressed. Antenna null steering and direction of arrival algorithms for interference minimization and throughput maximization...
