[amsat-bb] Satellite Tracking Engine

Hello

I used to make use of predict using scripts

Since then the raspberry pi and arduinos have come along

What LINUX satellite tracking program could be queried or send data about

Satellite elevation and angle

Satellite doppler frequency

I want to make a multi satellite radio and rotor control box with auto update keeps

I want to use perl to do the hard work

I want an arduino or the Pi to do the doppler and rotator
