Satellite Tracker

The Tracker was developed to be a general purpose satellite tracking program intended for tracking and plotting the positions of many different types of satellites for uses ranging from meteorology, communications, image reception and amateur radio. Screen displays include space views where the satellites are on a world map and Earth views showing satellites against a background of stars.
The program can also compute operational prediction data for satellites passing within range of a particular Earth station. eg times of acquisition and loss, maximum elevation and rising and setting azimuths.
To plot satellites the Tracker needs to be loaded with Kepler parameters. These are terms that provide a mathematical description of the orbit and are available in standard text format from various sources. Keplers need to be periodically refreshed and for computers with a web connection, Tracker has the ability to download these directly from the internet.
The Tracker can plot up to 4 satellites simultaneously which can be selected from an unlimited number stored on its current data file. As with Trackers other views, the Dialog bar at the bottom of the screen shows the predicted elevations, azimuths and times of acquisition and loss of signals from the selected satellites.
These are valid for the earth station at the position indicated by the bulls eye (ie. Southern California in the above example) which is also shown on the status bar. For marine stations constantly on the move, the bulls eye can be easily moved by simply dragging and dropping it with the mouse. Although not shown in the above, as an option, the world chart can be marked with the positions and names of major cities and islands. System requirementsProcessor speed 400MHz
