kep_reload - Update Predict’s Keplerian elements
KEP_RELOAD is a simple utility that forces an immediate reload of
PREDICT’s Keplerian database through a socket connection while PREDICT
is running in server mode. It is especially useful in environments
where PREDICT runs continuously, and periodic Keplerian element updates
are made outside of PREDICT, such as through scripts run through a
The "kepupdate" script found in this directory is an example of a
Keplerian element update script that can be run on an automated basis
through a crontab. It is designed to be placed in your home directory
under a subdirectory called "cronjobs". It downloads Keplerian orbital
data from www.celestrak.com using the HTTP protocol. (The "wget"
utility, available from the Free Software Foundation, is required, and
is included in many Linux distrubutions.)
Type crontab -e to edit your crontab. Simply add the following entry:
0 8 * * * kepupdate
and your orbital database will update each morning at 8:00 AM (provided
you have a network connection at that time).
See the crontab man page for more information on editing your crontab.
