POP expects ship navigation data to appear in C:\radar\cns. There is a
script on the profiler PC called shipdat.py, and a shortcut to it on the
desktop. There is a copy of that shortcut in the Startup folder, so that
the script starts when the iss user logs in. The script just runs and echoes
the raw navigation data to the console window, and it writes to the ship.dat
file. If it is ever not running, just double-click the shortcut icon in the
lower left corner of the desktop that looks like a snake. It is ok to try
to run it while it is already running; in that case it will just exit without
interrupting the already running instance.
While POP is running, POP displays in the lower right the median filtered
ship data read from ship.dat. So it is a good idea to periodically check
those values and make sure they are consistent with the current data on the
ship's real-time data display, either on the video monitors or the web page.
They will not match exactly thought, because the ship.dat values are a median
of the last 30 seconds of ship data, so they lag behind the real-time values.
