English: A simulation of the original design of the GPS space segment, with 24 GPS satellites (4 satellites in each of 6 orbits), showing the evolution of the number of visible satellites from a fixed point (45°N) on earth (considering "visibility" as having direct line of sight).

The parameters used to simulate the orbits are: eccentricity (e) 0.05, inclination (i) 55° and a separation between orbits of 60° in the right ascension of the ascending node. Within each orbit, the four satellites are evenly spaced (the instant of pass through perihelion being arbitrary for the first satellite in each orbit). The orbital period of the satellites was taken to be 12 hours. The earth was considered a perfect sphere with a radius of 6400 km.

The time in the animation is running about 2880 times faster than real time (half a minute representing 24 hours), as clearly seen in the rotation of earth. The simulation was created using MATLAB and converted to animated gif format using Adobe ImageReady.
Deutsch: Eine Simulation von 24 GPS-Satelliten (4 auf jeder der 6 Umlaufbahnen), die die Anzahl der zu einer bestimmten Zeit nutzbaren Satelliten an einem fixen Punkt (45°N) zeigt.

Die Bahnen wurden mit folgenden Voraussetzungen simuliert: Exzentrizität (e) 0.05, Neigung (i) 55° und Trennung zwischen den Bahnen von 60° in der Rektaszension des aufsteigenden Knotens. Innerhalb der Bahnen sind die Satelliten gleichmäßig verteilt (die Position des ersten Satelliten wurde willkürlich gewählt). Die Satelliten umrunden den Planeten innerhalb von 12 Stunden. Der Planet ist eine ideale Sphäre mit einem Radius von 6400 km.

Der Zeitraffer beschleunigt die Animation ca. um das 2880-fache, was dazu führt, dass 24 Stunden in einer halben Minute vergehen (siehe Umdrehung des Planeten). Die Simulation wurde mit MATLAB erstellt und mit Adobe ImageReady ins GIF-Format übertragen.
Italiano: Una simulazione del progetto originale dell'allocazione spaziale GPS, con 24 satelliti GPS (4 satelliti ciascuno su 6 orbite), la quale mostra l'evoluzione del numero di satelliti visibili da un punto fisso (45 ° N) sulla terra (considerando la "visibilità" "come avere una linea di tiro diretta).

I parametri utilizzati per simulare le orbite sono: eccentricità (e) 0,05, inclinazione (i) 55° e una separazione tra le orbite di 60° nell'ascensione destra del nodo ascendente. All'interno di ciascuna orbita, i quattro satelliti sono distribuiti uniformemente (l'istante del passaggio attraverso il perielio è arbitrario per il primo satellite in ciascuna orbita). Il periodo orbitale dei satelliti era di 12 ore. La terra è stata considerata una sfera perfetta con un raggio di 6400 km.

Il tempo nell'animazione corre circa 2880 volte più veloce del tempo reale (mezzo minuto rappresenta 24 ore), come si vede chiaramente nella rotazione della terra. La simulazione è stata creata con MATLAB e convertita in formato GIF utilizzando Adobe ImageReady.
