Research ArticleOpen accessIn the keywordsSpace Debris Removal Mechanism Using CubeSat with Gun Shot FacilitiesShankar Bhattarai, Jie-Rou ShangSpace derbies is a very perilous problem and most of the proposed methods for space debris removal are not successfully serviceable for all sized space junk. Keeping in view the limitation of the existing methods of debris removal techniques an active approach is needed and in this regard required to be instigated purposefully. In more than half a century of … …American Journal of Applied Sciences, Vol. 15, Issue 9 · 15 Nov 2018 · 8,211 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulti-Satellite Custody of Moving Ground TargetsDavid SchusterMaintaining persistent custody of ground targets from Low Earth Orbit (LEO) is a key challenge in space-based surveillance and reconnaissance. Traditional rule-based tasking strategies struggle with scalability as the number of assets and targets grows. In this paper, we present a centralized Reinforcement Learning (RL) approach using Proximal Policy Optimization (PPO) to coordinate four LEO satellites tasked with tracking two … …Journal of Computer Science, Vol. 22, Issue 3 · 25 Mar 2026 · 1,575 accessesView PDFCite
Research ArticleOpen accessIn the abstractRadar Cross Section Modelling and Analysis of Static and Dynamic Targets using MATLABPunam Pande, Sreemathy R, Mousami TurukRadar Cross Section (RCS) is an important characteristic of the electromagnetic system for target detection. This study presents detailed modelling of Radar Cross Section (RCS) of static simple objects like sphere, cylinder, triangular plate, circular flat plate, truncated cone and complex objects using MATLAB Radar toolbox. The RCS modelling of simple objects is also done with MATLAB POFACET GUI 4.3 … …Journal of Aircraft and Spacecraft Technology, Vol. 6, Issue 1 · 21 Mar 2022 · 11,024 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Energy for Aerospace VesselsRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.The advances in solar technology and electric propulsion now offer the promise of new, very capable space transport systems that will allow us to effectively explore the solar system. NASA has developed many concepts of space-powered spacecraft with power levels ranging from tens to hundreds of kilowatts for robotic and asteroid-driven missions and Mars. This paper describes two electrical/chemical propulsion … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 4 · 4 Nov 2017 · 8,009 accessesView PDFCite
