I wanted a simple program that showed when target spacecraft would be above the horizon. I remembered a picture of an old program that Rob Bruninga posted on AMSAT-BB some time ago. I could not find that picture, but I built something similar and it looks like this: http://www.g0kla.com/klatrack/klatrack_dark.png
It's a simple program that plots the elevation of upcoming satellite passes as a horizontal display and then updates it in real time. It does a one time calculation to fill its buffer of positions, then its pretty efficient because it just calculates the next position it needs in the future.
The details and the download are here: http://www.g0kla.com/klatrack/index.php
Thanks again to Dave Johnson (G4DPZ) for his port to Java of John Maglicane's (KB2BD) predict library.
The is made available under the Gnu GPL and I will upload the code to github when I get a chance.

Hi Joe,
Are you on Windows? Do you get nothing when you double click the exe? What version of Java do you have installed? Maybe it is silently crashing? Is the exe still there? You anti-virus might have deleted it.
If you have java in your path try running it from the command line and let me know what error it prints out. e.g. open a command prompt. Go to the install directory. Type java -jar KlaTrack.jar If java is not in the path then use the full path to java.exe.

I GOT IT WORKING! YAY!
And I LOVE IT!
BUT.... And there always is a BUT isn't there.
The "Past Hours" Setting,,
Can we make it have like 10 minute increments?
Zero time and the time it is right now is dead on the end of the window, so it's hard to see whats has very recently happened, Yet when in only 2 hour future mode even just one hour Past setting uses up a LOT of the window,
Like in 10 Minutes increments would be awesome!
