Orbit prediction and Earth shadow modeling for Chandrayaan-2 Orbiter

Astrophysics and Space Science, 2021
Chandrayaan-2, India’s second Moon mission, comprised of Orbiter, Lander and Rover modules was launched on July 22, 2019. The Chandrayaan-2 (CH2) Orbiter, which carries eight scientific payloads, is placed into a circular lunar orbit of 100 km altitude with an orbital period of around 120 minutes. After the successful injection of the spacecraft in the

Unstable periodic orbits and prediction

Physical Review A, 1991
A hierarchical approximation of a generic chaotic attractor can be formulated in terms of unstable periodic orbits. We demonstrate the possibility of extracting the most dominant unstable periodic orbits from a measurement of a time-continuous flow. Since unstable periodic orbits not only represent the static properties of the system but also dominate ...

Orbit Prediction Technology

2018
The OTV fulfills orbital maneuver by selecting appropriate transfer points to save fuels. Usually, before the orbital maneuver, it shall carry out non-powered free sliding in large elliptic orbit for a long time. During such process, due to the longer sliding period, the error of inertial navigation will be accumulated as time elapses.

Nimerical Averaging in Orbit Prediction

AIAA Journal, 1972
This paper is a presentation of some useful aspects of a numerical averaging technique that has been applied with considerable success to the orbit prediction problem for artificial satellites. The method has been tested in a variety of situations wherein the satellite is subjected to combinations of perturbations for which adequate analytic theories ...
