Each map has the following components: A
colored world map ("equirectangular" projection - not Mercator!) with linear degree scales along both latitude and longitude; Grid lines, spaced every 30 degrees in each direction; Satellite position marker (small circle); and Observer position marker (larger circle with dot in center). The colors of some of these features can be changed from the Main Window Setup:Colors
Optional features include:
Ground track (a trail of solid dots representing previous satellite positions); Footprint;
secondary satellite marker (square symbol); Other observer locations (two groups); Solar illumination (a sun icon, representing the subsolar point, and a line representing the terminator or twilight locus).
At the bottom of the map is a strip showing some tracking parameters - next AOS,
azimuth/elevation from the observer; satellite latitude, longitude, altitude;
and doppler shift.

[NOTE: In earlier versions of the documentation, I referred to the Map Windows
as "Tracking Windows". I have found this to be confusing, since the Info

but by the Tracking Info Window. Hence the new designation: "Map Window".]
