Estimating Harmonic Coefficients of Asteroids through LiAISON Navigation
Jun Maruyama, Simone Servadio
This paper evaluates the Linked Autonomous Interplanetary Satellite Orbit Navigation (LiAISON) method in near two-body asteroid systems. While LiAISON's usefulness has been proven…
Fully Multiplicative Attitude and Orbit Determination for Deep space Navigation
Ridma Ganganath, Simone Servadio
This paper develops a geometry-consistent fully multiplicative unscented Kalman filter (FM-UKF) for joint spacecraft attitude--orbit estimation with simultaneous dual star-tracker…
Beyond the Cube: Overlapping Grid Methods for Debris Collision Risk Assessment
Yacob Medhin, Simone Servadio
The cube method reduces conjunction screening in orbital debris simulations to cost by evaluating only object pairs sharing the same grid cell at each snapshot, bu…
Compensating Star-Trackers Misalignments with Adaptive Multi-Model Estimation
Ridma Ganganath, Simone Servadio, David Daeyoung Lee
This paper presents an adaptive multi-model framework for jointly estimating spacecraft attitude and star-tracker misalignments in GPS-denied deep-space CubeSat missions. A Multipl…
Star Tracker Misalignment Compensation in Deep Space Navigation Through Model-Based Estimation
Ridma Ganganath, Simone Servadio, David Lee
This work presents a novel adaptive framework for simultaneously estimating spacecraft attitude and sensor misalignment. Uncorrected star tracker misalignment can introduce signifi…
A Data-Driven Approach to Estimate LEO Orbit Capacity Models
Braden Stock, Maddox McVarthy, Simone Servadio
Utilizing the Sparse Identification of Nonlinear Dynamics algorithm (SINDy) and Long Short-Term Memory Recurrent Neural Networks (LSTM), the population of resident space objects, d…
The Sustainability of the Leo Orbit Capacity via Risk-Driven Active Debris Removal
Yacob Medhin, Simone Servadio
The growing number of space debris in Low Earth Orbit (LEO) jeopardizes long-term orbital sustainability, requiring efficient risk assessment for active debris removal (ADR) missio…
Markers Identification for Relative Pose Estimation of an Uncooperative Target
Batu Candan, Simone Servadio
This paper introduces a novel method using chaser spacecraft image processing and Convolutional Neural Networks (CNNs) to detect structural markers on the European Space Agency's (…
