Editor's Note: This file was selected as MATLAB Central Pick of the Week

This application consists of a real time simulator of GPS constellation, including a suite of visualizations:
- World map with satellite geodetic positions, ground tracks and numeric GPS data,
- Sky map with satellite polar coordinates with regard to the local tangent plane,
- Visibility indicators, with satellites rise and set instants, and the number of visible and healthy satellites,
- Orbital planes and GPS constellation status.

The computation of GPS data is based on:
- Yuma or SEM format almanac (available online),
- UTC time from computer or user defined GPS time,
- User defined reference position,
- GPS operational advisory or constellation status (available online).
