1. Orbitography
This section recalls the laws of orbital motion and the modeling of uncertainties.
These models are used to predict conjunctions and assess the associated risks.
1.1 Orbital motion
A Keplerian orbit is the trajectory followed by a material point in a central gravity field. This orbit is a conic characterized by its orbital parameters (a, e, i, Ω, ω, θ) in the geocentric Galilean reference frame (O center of the Earth, Z axis to the North Pole,...
