Magnetic Field Aided Vehicle Localization with Acceleration Correction
Mrunmayee Deshpande, Manoranjan Majji, J. Humberto Ramos
This paper presents a novel approach for vehicle localization by leveraging the ambient magnetic field within a given environment. Our approach involves introducing a global mathem…
A Rapid Trajectory Optimization and Control Framework for Resource-Constrained Applications
Deep Parikh, Thomas L. Ahrens, Manoranjan Majji
This paper presents a computationally efficient model predictive control formulation that uses an integral Chebyshev collocation method to enable rapid operations of autonomous age…
Robust Proximity Operations using Probabilistic Markov Models
Deep Parikh, Ali Hasnain Khowaja, Manoranjan Majji
A Markov decision process-based state switching is devised, implemented, and analyzed for proximity operations of various autonomous vehicles. The framework contains a pose estimat…
Pose estimation of CubeSats via sensor fusion and Error-State Extended Kalman Filter
Deep Parikh, Manoranjan Majji
A pose estimation technique based on error-state extended Kalman that fuses angular rates, accelerations, and relative range measurements is presented in this paper. An unconstrain…
Proximity operations of CubeSats via sensor fusion of ultra-wideband range measurements with rate gyroscopes, accelerometers and monocular vision
Deep Parikh, Hasnain Khowaja, Ravi Kumar Thakur +1
A robust pose estimation algorithm based on an extended Kalman filter using measurements from accelerometers, rate gyroscopes, monocular vision and ultra-wideband radar is presente…
Estimation of inertial properties of a rigid structure maneuvered by satellite modules
Deep Parikh, Manoranjan Majji
The LASR Laboratory is investigating the use of free-flying spacecraft modules in several on-orbit, servicing and manufacturing (OSAM) activities. Previous work consists of the sys…
A Scalable Tabletop Satellite Automation Testbed:Design And Experiments
Deep Parikh, Ali Hasnain Khowaja, Nathan Long +4
This paper presents a detailed system design and component selection for the Transforming Proximity Operations and Docking Service (TPODS) module, designed to gain custody of uncon…
Disturbance-Robust Backup Control Barrier Functions: Safety Under Uncertain Dynamics
David E. J. van Wijk, Samuel Coogan, Tamas G. Molnar +2
Obtaining a controlled invariant set is crucial for safety-critical control with control barrier functions (CBFs) but is non-trivial for complex nonlinear systems and constraints.…
Icy Moon Surface Simulation and Stereo Depth Estimation for Sampling Autonomy
Ramchander Bhaskara, Georgios Georgakis, Jeremy Nash +5
Sampling autonomy for icy moon lander missions requires understanding of topographic and photometric properties of the sampling terrain. Unavailability of high resolution visual da…
