PREDICT is an open-source, multi-user satellite tracking and orbital prediction program by John A. Magliacane, KD2BD.
This repository contains a simplified fork, merged with KD2BD's version 2.2.6, originally by @koansys, with the following modifications:
- All additioncal clients and utilities are removed.
- Installation scripts from KD2BD's version 2.2.6 are removed.
- The original color scheme is corrected so that the program can be run normally on a solarized iTerm. :)
- longitude range is changed from
0~360degrees to-180~180degrees. (Negative degrees specify the other semisphere.)
- Project web page
- Project GitHub page
- Thanks to the fork of koansys for the macOS port
make clean && makeFirst time users will be asked to enter their groundstation latitude and longitude in decimal degrees or in degree, minute, second (DMS) format.
Normally, PREDICT handles longitudes in decimal degrees WEST (0-360 degrees), and latitudes in decimal degrees NORTH. This behavior can be modified by passing the -east or -south command line switches to PREDICT when it is invoked.
Our station's altitude in meters above mean sea level, a recent set of Keplerian orbital data for the satellites of interest, and an accurately set system clock are also required if successful real-time satellite tracking is also desired.
Sources for such Keplerian data include http://www.celestrak.com/, http://www.space-track.org, and http://www.amsat.org/.
