Hmmm. I'm struggling to work out how to use a single satellite in orbit over the equator to determine position...

A Geo-Ranging Navigation System (GRNS) is a radio-navigation method that uses a geostationary satellite as a fixed reference point in space. By timing a radio signal’s round trip to the satellite, it determines range—the distance between the receiver and that orbital beacon. Combined with azimuth (compass bearing), elevation (angle above the horizon), and the satellite’s known longitude, the GRNS can precisely locate a vessel or surface station on a planetary body. The azimuth shows direction, the elevation shows height above the horizon, and the range defines distance to the satellite.
If that is the case why is it any more challenging to get a bearing than with GPS? It either provides the data automatically or you cannot get LOS to the stationary satellite and it doesn't. The positional fix is as accurate as the receiving system makes it.
To the roll to plot a course is the skill to use that positional fix. Whether you can get the fix itself is entirely determinable by the referee or the setting (such as the comms satellite coverage in the Tarsus setting book).
