WXtrackGL at work
This screen grab shows WXtrackGL at work. I used the scroll bars to locate myself just to the north of the equator. You can see the earth, with a relief map superimposed, and the tracks of a number of satellites. The orbit of my primary satellite is shown as a red circle. You can substitute your own surface image on the earth, making WXtrackGL capable of viewing a variety of information in a 3D format. You can download WXtrackGL and use it free of charge. Whether you want to work in real-time, or step ahead a month at a time is up to you. Keep a constant viewpoint above your home location or anywhere on the earth, or fly along with the satellite. The program's status bar maintains a continual display of time, viewpoint, and satellite position.
