Geostationary Satellites Tracking

Matlab based application to predict the orbit and track the geostationary satellites in real time.

---------------------Geostationary Satellites Tracking--------------------
Geostationary Satellites Tracking is a Matlab based application to predict the orbit and track the geostationary satellites in real time.
This application predicts the orbital position of geostationary satellites from Public Two-Line Element Orbital Information (TLE). The TLE are created by United States Air Force / Department of Defense (DoD), that tracks all detectable objects in Earth orbit, creating a corresponding TLE for each object, and makes available the TLEs for non-classified objects on the internet.
The satellites orbit are predicted/propagated using Simplified perturbations models codes (SGP4) from “Revisiting Spacetrack Report #3” and The results of the orbit prediction are displayed in different types of 2D and 3D plots. The TLE data are updated constantly from http://celestrak.com.
