چکیده
Acquiring accurate space object orbits is crucial for many applications such as satellite tracking, debris detection, and collision avoidance. The widely used two-line element (TLE) method estimates the position velocity of objects in space, but its accuracy can be limited by various factors. A combination multiple TLEs advanced modeling techniques batch least squares differential correction high-precision numerical propagators significantly improve TLE reliability, ensuring better surveillance. Previous studies analyzed additional factors that may influence evaluated Starlink using precise ephemeris data from SpaceX. results indicate utilizing orbit determination enhance performance prediction methods, particularly when compared to SGP4. By leveraging 10-day TLEs, 5-day predictions improved approximately twofold. Additionally, producing two pseudo-observations within an orbital period near epoch yields greatest effect on accuracy, with this distribution increasing 10% a uniform distribution. Further research explore more fusion machine learning approaches optimize operations space.

KAM torus frequency generation from two line element sets
The Kolmogorov Arnold and Moser (KAM) theorem states that a lightly perturbed Hamiltonian system will have solutions which lie on a torus. Earlier work by the second author has shown that most Earth satellite orbits perturbed by the geopotential lie on KAM tori. The problem then arises as to how to convert the current satellite tracking orbits to KAM tori. A KAM torus is characterized by three ...

15 صفحه اولOn Avoidable Two Element Sets of Partial Words∗
This paper considers the problem of finding avoiding words given sets of partial words of the form {a 1a m2 . . . ka, b 1b n2 . . . lb} where a and b are letters in the alphabet and is a hole, or showing the set is unavoidable. Such a set is avoidable if and only if there exists a two-sided infinite full word with no factor compatible with a member of the set, and this word is called the avoidi...
