1st ACM Workshop on Satellite Networking and Computing (SatCom)

The space industry is currently experiencing an unprecedented surge in the development of low-earth orbit (LEO) satellite mega-constellations, in order to meet the growing demand for global connectivity services and applications such as ubiquitous communication, smart transportation, smart cities, maritime surveillance, and disaster rescue. However, these mega-constellations present unique challenges for networking and computing in space due to their fundamentally different infrastructure from cloud and edge computing on the ground. In a LEO constellation, each satellite moves at high speed relative to both the Earth and other satellites, and must maintain its orbit at a speed of 27,000 km/h at an altitude of 550 km. Additionally, the reduced weight and volume of the satellites in mega-constellations increase the difficulty of designing networking and computing systems. The harsh space environment, characterized by deep vacuum conditions, radiation, strong vibrations, and extreme temperature ranges, further adds to the complexity.

As a result, the research community is taking a growing interest in exploring the opportunities and challenges associated with LEO mega-constellations. The proposed workshop aims to provide a platform for researchers to exchange ideas, share their latest research findings, and discuss the current state of the field. This workshop is particularly timely, as it will significantly contribute to advancing our understanding of the complexities involved in designing networking and computing systems for LEO mega-constellations. Such an understanding is essential for achieving universal connectivity and computing in space.
