A Norm-Minimization Algorithm for Solving the Cold-Start Problem with XNAV Open

Linyi Hou, Zachary R. Putnam · 2023

An algorithm is presented for solving the cold-start problem using observations of X-ray pulsars. Using a norm-minimization-based approach, the algorithm extends Lohan's banded-error intersection model to 3-dimensional space while reducing…
