R2D2M2 -- ISS Antenna Tracker

Introduction: R2D2M2 -- ISS Antenna Tracker

Connecting to the International Space Station (ISS) requires tracking a moving object traveling at 17,000 MPH orbiting 250 miles above the Earth. This is actually moving a little slower than the second hand on your watch. However, this is moving faster than you may realize.

You could purchase a commercial Az/El rotor system for $1,350 from Yaesu or you can build your own.

Let's get started!

###

This project does not cover the assembly of Arduino micro controllers. This may be a future topic covered separately.

###

Useful tools: 7/64" hex key, 3/32" hex key and a #1 Phillips Screwdriver

    Did you ever document anywhere adding Arduino control or anything like that?
