Geometric Solution to the Angles-Only Initial Orbit Determination Problem [PDF]
The Journal of the astronautical sciences, 2023 Initial orbit determination (IOD) from line-of-sight (i.e., bearing) measurements is a classical problem in astrodynamics. Indeed, there are many well-established methods for performing the IOD task when given three line-of-sight observations at known ...

Applicable Tracking Data Arcs for NORAD TLE Orbit Determination of the KOMPSAT-1 Satellite Using GPS Navigation Solutions [PDF]
Journal of Astronomy and Space Sciences, 2005 NORAD Two Line Element (TLE) is very useful to simplify the ground station antenna pointing and mission operations. When a satellite operations facility has the capability to determine NORAD type TLE which is independent of NORAD, it is important to ...

Measuring the Orbit Drift of Near-Earth Asteroids by the Yarkovsky Effect
The Astrophysical Journal, 2023 The Yarkovsky effect causes the semimajor axis drift of near-Earth asteroids. The drift can be detected by a precise orbit determination process. Using the proposed algorithm, 2233 out of 27,078 near-Earth asteroids are chosen as the initial candidates ...
