Determining the influence on orbit prediction based on uncertainties in atmospheric models
Orbit prediction and knowing its uncertainties is a key part in planning collision avoidance maneuvers or conducting re-entry estimations. For high accuracy forecasts numerical propagators are used. These propagators use force models to estimate the perturbing elements that affect a satellite's orbit. Especially on low Earth orbits (LEO) with decreasing perigee altitude the atmosphere becomes the dominating perturbing force. The available atmospheric models are complex in nature and react verydoi:10.24355/dbbs.084-201601251157-0 fatcat:sy7lzh77vjfbhgklu2o7t2g5wa
