I am working on a little project here
It is a raspberry Pi, that is connected to the APRS-IS and will eventually also take in user reports as well
It is on my static ip http://220.127.116.11/
It is called "Satellite Reporter"
It is intended to provide a dashboard, stats in graphical format and also data streams.
Please let me know if you want any features added as this project grows.
I see a user input screen and drop downs for satellites.
I will make an iPhone and Samsung compatible version.
The back end is MySQL and PERL and CGI
I will add ISS for the time being, please check back often for updates.
I think it best to use UTC times for the time being.
