Introduction - Features

The principal feature of the program is a series of map windows, one per satellite, which display the current position of the satellite and the observer on a simple world map, together with information such as bearing (azimuth), distance, and elevation above the observer's horizon. (To see the latest changes, bug fixes, and updates, click here). Additional noteworthy features include:
* Simultaneous tracking of up to 20 satellites.
* Real-time, pseudo-real-time, and manual calculation modes.
* Choice of 4 tracking algorithms.
* A view from space map presentation showing what a particular satellite sees.
* Computation of Doppler shift and path loss for communications satellites.
* Selectable tracking detail, including doppler shift and free-space path loss, for a single satellite.
* Utility functions for modifying and comparing published element sets, including post-launch updating of pre-launch elements, and saving composite data files compiled from various sources.
* DDE server interface to tracking-antenna or doppler-shift correction hardware controllers.
* Tracking data (Keplerian element sets) read from standard, off-the-air bulletins in three different formats (up to 500 satellites). No pre-processing is needed, just select a bulletin file.
* Observer (QTH) data (latitude, longitude) may be imported from a simple text database (up to 1000 locations).
* Printing of tables of tracking data (Ephemerides) in several formats. Table printing does not interrupt tracking. Table output may be directed to a disk file.
* On-line help including direct access to text information about each satellite from the map windows.
* Standard Windows interface for all functions - no commands to memorize. Both mouse and keyboard can be used for most functions.
