Abstract
Large constellations of hundreds or thousands of satellites in low Earth orbit are a recent development that is both creating new space-based services and creating challenges for space traffic management especially considering the number of new constellations and corresponding satellites proposed. The large numbers of satellites, orders of magnitude beyond historic norms and the new modes of operations present a range of technical, policy and communications challenges. These challenges are discussed along with proposed and some implemented solutions. Several recommendations are made to improve the safety of large constellations while enabling continued innovation.
期刊介绍:
Acta Astronautica is sponsored by the International Academy of Astronautics. Content is based on original contributions in all fields of basic, engineering, life and social space sciences and of space technology related to:
The peaceful scientific exploration of space,
Its exploitation for human welfare and progress,
Conception, design, development and operation of space-borne and Earth-based systems,
In addition to regular issues, the journal publishes selected proceedings of the annual International Astronautical Congress (IAC), transactions of the IAA and special issues on topics of current interest, such as microgravity, space station technology, geostationary orbits, and space economics. Other subject areas include satellite technology, space transportation and communications, space energy, power and propulsion, astrodynamics, extraterrestrial intelligence and Earth observations.
