Initial Orbit Determination Based on Propagation of Orbit Sets with Differential Algebra
, 2017 The object of this paper is the initial orbit determination of an orbit set compatible with an observational arc by means of differential algebra. The initial estimate is retrieved as a truncated power series expanded with respect to the uncertainties in the measurements. The analysis of the region is performed with the automatic domain splitting, that

Dealing with uncertainties in angles-only initial orbit determination [PDF]
, 2016 A method to deal with uncertainties in initial orbit determination (IOD) is presented. This is based on the use of Taylor differential algebra (DA) to nonlinearly map uncertainties from the observation space to the state space.

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 ...
