Collision Risk Assessment for Derelict Objects in Low-Earth Orbit Michael J. Nicolls(1) and Darren McKnight(2) (1) LeoLabs, Inc., PO Box , Menlo Park, CA USA, [email protected] (2)Centauri, Conference Center Drive, Chantilly, VA USA, [email protected] ABSTRACT Massive, defunct objects in low-Earth orbit . antenna tracking. Our systems are specifically designed for low and medium earth orbits that support Remote Sensing, Earth Observation, and TT&C applications. We offer a range of X/Y tracking antennas from 30 centimeters to 11 meters coupled with our . terrestrial networks. Satellite systems are location insensitive and can be used to extend the reach of networks and applica-tions to anywhere on the earth with a fixed constellation cost. A low earth orbit (LEO) or medium earth orbit (MEO) satellite system is a set of identical satellites that are launched. A Performance Analysis of The IRIDIUM® Low Earth Orbit Satellite System THESIS Presented to the faculty of the Graduate School of Engineering of the Air Force Institute of Technology Air University In Partial Fulfillment of the Requirements for the Degree of Master of Science (Electrical Engineering) Carl E. Fossa, Jr. Major, USA June,

In particular, the low-earth orbit (LEO) satellite becomes a better choice of an access point of satellite IoT based on B5G wireless networks due to its appealing characteristics, e.g., low power consumption and low transmission delay [5], [6]. In order to . Mega-constellations in low-Earth orbit plan to offer latency on the order of 30 milliseconds (ms), comparable to the 10–50 ms latency of terrestrial fiber systems, and far lower than the ~ Traditionally, the satellite industry has relied on geosynchronous earth orbit (GEO) satellites that take years to build and require very expensive launches to deliver them to orbit. Latency issues due to the distance of these orbits limit the ability of these satellites to be used for real-time communications like voice or live video. NASA is committed to stimulating the economy in low-Earth orbit as the next step in humanity’s exploration and expansion into the solar system.

The Low Earth Orbit (LEO) satellite payloads significantly contributed to the industry growth with a revenue share of over 35% in Since these satellites provide a clear portrait of the surface of the earth along with a minute level of detail, they have gained considerable prominence. system designers and managers with real options that enable them to match the system evolution path to the actual unfolding demand scenario. A case study demonstrates significant economic benefits of the proposed approach, when applied to Low Earth Orbit (LEO) constellations of communications satellites. In the process, life cycle cost and capacity.
