The last several decades have resulted in an unfortunate byproduct of space exploration and development: orbital debris. Satellites in Low Earth Orbit have been required to make an ever increasing number of course corrections in order to avoid collisions. Despite efforts to the contrary, collisions continue to occur, each time creating additional debris and increasing the requirement for the remaining satellites to maneuver. Every required maneuver decreases a satellite's service life. The purpose of this study is to develop a minimum thrust profile to maneuver an orbiting satellite out of its projected error ellipse before a collision occurs. For comparison, both the impulsive and continuous thrust cases were considered as well as in-plane versus out-of plane maneuvering. This study made use of the Radau Pseudospectral Method to develop this minimum thrust profile. This method was run in MATLAB(r) using General Pseudospectral Optimal Control Software (GPOPS-II). Once the optimal solution was obtained, Systems Tool Kit(r) was used to simulate the resulting calculated trajectories and confirm avoidance of the error ellipse.

This book describes advanced space technology creating DigiPLOT the ship collision avoidance system in production for 13 years. Discover the cover-ups, the IMO politics, and the dangerous fallacy that collision avoidance equipment is not necessary because it is not "cheap enough" and "it won't happen to my ship." Innovator and Air Force Space Pioneer John C. (Jack) Herther founded Iotron Corporation a half-century ago, his mission was to prevent ship's oil spills from destroying our environment. His company pioneered DigiPLOT the "hands-off" anti-collision self-plotting radar, installed on 550 ships with 60 million hours of use at sea. Their Transit satellite/Loran C navigation system was fitted on 34 largest supertankers with accuracy better than GPS until 20 years later. Had DigiPLOT been aboard the Torrey Canyon, Costa Concordia and the Esso Valdez, these names would not have their NAMES NOTED for their infamous collisions or groundings at sea. The more recent seven tragic Navy ship collisions/disasters killed 17 sailors, and cost taxpayers billions in ship repair. In addition, his company invented a way to help save the planet from climate change. Just 15 of the world's biggest ships may now emit as much pollution as all the world's 760 million cars. Iotron's adaptive autopilot, DigiPILOT was developed to reduce fuel cost and reduce greenhouse gases. DigiPILOT was proven with 2% fuel savings over a conventional autopilot on 20 ships. It is an affordable add-on retrofit that complies with IMO SEEMP Steering Efficiency 4.18 and can be implemented inexpensively on 70,000 existing ships. John (Jack) Herther was the founder and inventor of Automated Ship Collision Avoidance (founding both Iotron & Automate Marine). He became an Air Force Space Pioneer and was inducted into the Space Hall of Fame in 2003.

This volume addresses developments in European space policy and its significance for European integration, using discourse theory as a framework. It seeks to address the developments in European space policy by examining several sensitive security questions linked in general with space activities, on the one hand, and the interplay between space policy and security policy in the European Union (EU) on the other. The book argues that defence and security matters should be studied for a better understanding of space projects in their historical, political, economic, legal and social context. The volume seeks to answer the following key questions: • What can space policy contribute to European identity formation and the integration process? • What are the interests of member states/EU institutions in space? • How is space policy perceived by European institutions, and how have they been engaged in the policy process to promote activity in space? • In which ways is the EU engaged in space, in terms of policy areas, e.g. foreign policy, industrial policy, security and defence policies? • What is the impact of institutions on the policy-making process in European space policy? This book will be of interest to students of EU policy, space policy, discourse studies and International Relations in general.

Satellites flying in close proximity can provide many advantages over a single monolithic system. However, the balance between minimising fuel and maintaining safe trajectories creates the inevitable dilemma of trading fuel for safety or vice versa to preserve formation life. Multi-satellite trajectory planning for proximity operations is traditionally completed days or weeks in advance of a manoeuvre due to the complex dynamics of relative motion. Allowing satellite formations the flexibility to perform path-planning operations on-board each spacecraft can significantly reduce the ground operations burden and increase the responsiveness of a formation to reconfiguration events. To meet rapid manoeuvre requirements for future multi-satellite missions, collision-free path-planning and execution must be completed on-board a satellite. This thesis presents a novel approach for real-time multi-satellite collision avoidance path-planning and execution which can be implemented autonomously on-board individual spacecraft in a formation. A systematic study of the effects of perturbations during optimal reconfiguration and a heuristic model of reconfiguration in relative motion creates a basis for building multi-satellite collision-free trajectory planning and control tools. Utilising an analytic reconfiguration model, a new semi-analytic collision identification approach is developed which increases the dimensional understanding and allows for focused collision avoidance planning. Implementation of this approach in conjunction with a sequential pareto-optimal trajectory deviation strategy to produces an innovative collision avoidance path-planner. A new analytic model predictive control system is developed which implements collision-free manoeuvre plans in the presence of perturbations and other uncertainties. Additionally, approaches are presented for extending the heuristic motion model. A new relative motion model is developed including J2 perturbations and using cylindrical coordinates which allows for higher-fidelity modelling of long-duration, large-separation relative motion. Such models further decrease fuel usage during the execution of multi-satellite collision-free reconfiguration. I Comparisons with traditional methods demonstrate a substantially reduced computational burden allowing these to be the first such path-planning tools to be validated on spacecraft hardware. Controller demonstration also shows a dramatic decrease in fuel usage when compared with traditional analytic controllers at nearly equal computation time. Satellite hardware testing validates that both the semi-analytic collision avoidance and analytic model predictive controller are real-time solutions to safe on-orbit formation reconfiguration.

Can future (AI) control systems be developed to be applied to automated test any spacecraft flight systems to ensure which are safe to leave earth to fly to space? Is (AI) automated system testing tool more accurate to achieve the testing safe measurement result to reduce the space flight risk than human testing effort? To answer these questions, scientists need to attempt to compare (AI) testing system and human effort to test many times of spacecraft flights in order to confirm whether (AI) testing system will be more accurate than human effort testing to every spacecraft equipment before it will fly to space.Fourthly, in autonomous space exploration problem solution aspect, when a spacecraft encountered a somewhat unique problem as it moves further and further from earth. The increasing distance makes it take from ground-based controllers. As such, a spacecraft that will be any significant distance from earth most have some problems need to be able take collision avoidance actions and to reestablish communications with earth should they are lost.The use of (AI) autonomous technologies started with meeting these basic requirements and performing actions ( such as docking), which required too much. However, (AI) technology will have possible to be implemented because it can make missions better and less expensive. When, (AI) technology is participated to solve any unpredictable challenges when any a spacecraft leaves our earth to fly to space for future mission plans. It is likely the future existing space site networks will expand and some of which may be in remote locations. As such, there is an even greater need for (AI) automated challenge solution technology to facilities the operation of these various space stations within budget.Consequently, future (AI) technology can be used in space on communication, space exploration, automated ground based testing, autonomous space exploration problem solution aspects. Nowadays, human is waiting when (AI) technology can be invented to assist space development, such as the day comes.
