This project provides Arduino C++ libraries for tracking satellites. It includes:

an implementation of the Plan-13 algorithm of James Miller a means of storing and accessing keplerian elements in EEPROM a flexible morse signaling library a library to control the Yaesu FT-817 amateur radio through its CAT interface a library to simplify the use of Ansi terminal signals. The examples provided generate real-time satellite location and azimuth / elevation data for up to fifteen satellites using a single $4 chip, the ATMega328. With a small additional EEPROM, dozens of satellites can be tracked in real time. qrpTracker is meant for amateur satellite enthusiasts and computing hobbyists.

(This project is not a complete trackbox. If you need a complete and functional tracking solution, consider the LVB Tracker, designed and programmed by G6LVB.)
