NAME
gsat - Graphical Predict client SYNOPSIS
gsat [ -u ] [ -l ] [ -g ] [ -h ] [ -s predictservername ] DESCRIPTION
The gsat program is a graphical client for the 'predict' satellite tracking program running in server mode, built using gtk. Visualization of satellite coverage and orbital ground tracks are one feature of this application, but it also allows for display and con- trol of Doppler corrected frequencies of a radio and antenna rotor control via predict(1). Since this program can be run on a different machine than predict, there is no dependency specified... but you need access to a copy of 'predict' installed somewhere on the network for this programs to be useful! OPTIONS
-u Times in UTC -l Times in Local Time Zone -g Show grid -h Show short usage text -s Predict Server Name ENVIRONMENT

NAME
kep_reload - Update Predict's Keplerian elements SYNOPSIS
kep_reload DESCRIPTION
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 crontab. 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. AUTHOR
