RFSoC-Based Integrated Navigation and Sensing Using NavIC
Riya Sachdeva, Aakanksha Tewari, Sumit J. Darak +2
Prior art has proposed a secondary application for Global Navigation Satellite System (GNSS) infrastructure for remote sensing of ground-based and maritime targets. Here, a passive…
Time Invariant Sensor Tasking for Catalog Maintenance of LEO Space objects using Stochastic Geometry
Partha Chowdhury, Harsha M, Chinni Prabhunath Georg +2
Catalog maintenance of space objects by limited number of ground-based sensors presents a formidable challenging task to the space community. This article presents a methodology fo…
Orbital Collision: An Indigenously Developed Web-based Space Situational Awareness Platform
Partha Chowdhury, Harsha M, Ayush Gupta +1
This work presents an indigenous web based platform Orbital Collision (OrCo), created by the Space Systems Laboratory at IIIT Delhi, to enhance Space Situational Awareness (SSA) by…
Modeling the position and velocity distribution of space objects by maximizing entropy with energy constraint
Partha Chowdhury, Sanat K Biswas
In this work, we have developed a 6-dimensional joint probability density function for the 3-dimensional position and 3-dimensional velocity vectors of space objects in the Low Ear…
Tracking an Untracked Space Debris After an Inelastic Collision Using Physics Informed Neural Network
Harsha M., Gurpreet Singh, Vinod Kumar +2
With the sustained rise in satellite deployment in Low Earth Orbits, the collision risk from untracked space debris is also increasing. Often small-sized space debris (below 10 cm)…
Position and Velocity estimation of Re-entry Vehicles using Fast Unscented Kalman Filters
Sanat Biswas, Li Qiao, Andrew Dempster
Application of two new UKF based estimation techniques with reduced processing time in re-entry vehicle position and velocity estimation problem using ground-based range and elevat…
Computationally Efficient Unscented Kalman Filtering Techniques for Launch Vehicle Navigation using a Space-borne GPS Receiver
Sanat Biswas, Li Qiao, Andrew Dempster
The Extended Kalman Filter (EKF) is a well established technique for position and velocity estimation. However, the performance of the EKF degrades considerably in highly non-linea…
A Novel a priori State Computation Strategy for the Unscented Kalman Filter to Improve Computational Efficiency
Sanat Biswas, Li Qiao, Andrew Dempster
A priori state vector and error covariance computation for the Unscented Kalman Filter (UKF) is described. The original UKF propagates multiple sigma points to compute the a priori…
