How to create a single satellite scenario with SatGen v3

The best sequence is to identify which satellite to select using the Trimble Planning Online service. Then download the relevant almanac using SatGen software. The selected almanac can then be modified using MS notebook. Only the selected Satellite ephemeris data should remain in the almanac file.

This file is then selected in the SatGen v3 software and the scenario created as normal.
