Satpack: Arduino Satellite tracking and doppler tuning

December 1, 2009 | Amateur Radio, Amateur Satellite | By: Mark VandeWettering

Bruce, VE9QRP has a nice video demoing his qrpTracker code (open source) running on an Atmel AVR microcontroller and tracking the Doppler of a cubesat as well as AO-51. Nifty.

Addendum: Back in January of 2008, I acquired my (then) new FT-817, and one of the first projects I did was to use my own implementation of Plan 13 to automatically tune the radio to follow a satellite’s Doppler shift. Here is my first recording of the (recently defunct) satellite LO-19.
