The relevance of delimitation debate in context of space tourism and space traffic management
… that a legally accepted boundary between air space and outer space would effectively close the existing gap within air and space law which has led to uncertain legal application over space activities. Technology changes in aircraft, spacecraft, combined with the growth of space activity, …

A Technical and Policy Needs Analysis for Space Traffic Management of Low Lunar Orbit
The number of artificial objects in space has grown exponentially in the last decade, encouraging a greater focus on space safety and sustainability. Much of this focus is on the detection, tracking, cataloguing, and coordination of objects in space, also known as Space Traffic Management, which …

African perspective on integrated space and air traffic management
Space Traffic Management (STM) is an emerging area of interest in the space sector because States and private actors are collaborating on ways to manage the growing congestion in orbit and to mitigate the impact of space debris and space weather as part of sustainable use and exploration of outer …

Reactive, Autonomous, Markovian Sensor Tasking in Communication Starved Environments
The current Space Traffic Management (STM) community was not prepared for the exponential increase in the resident space object (RSO) population that has taken place over the last several years. The combination of poor communication infrastructure and long scheduling lead times of the Space …

Navigating the Skies: An Exploration of Stakeholder Perspectives on Rules for Orbital Traffic Coordination using Grounded Theory and Case Study Research Methodologies
… rules, or regulations ("rules") of orbital traffic coordination to reduce the risk of collisions in space between active space objects. The research questions explored topics associated with areas for potential implementation of rules include maneuvering capabilities, liability and …

Encoding the Sensor Allocation Problem for Reinforcement Learning
Traditionally, space situational awareness (SSA) sensor networks have relied on dynamic programming theory to generate tasking plans which govern how sensors are allocated to observe resident space objects. Deep reinforcement learning (DRL) techniques, with their ability to be trained on simulated …

Characterization of the Effects of a Sun-Synchronous Orbit Slot Architecture on the Earth's Orbital Debris Environment
<p>Low Earth orbit represents a valuable limited natural resource. Of particular interest are sun-synchronous orbits; it is estimated that approximately 44% of low Earth satellites are sun-synchronous. A previously developed sun-synchronous orbit slot architecture is considered. An in-depth …
