Tool to plot a prediction of the amount of visible Iridium satellites depending on Geo-Coordinates and time. Be sure to have up-to-date TLEs of the Iridium sats at the ready. See requirements.txt for required Python 3 packages for the visibility.py script, which produces a CSV file for the set time resolution. plotSatVisibility.m can be used to produce JPGs and PDFs plots out of it (written with GNU Octave).
