SAEBERtrack Satellite Tracker This Project was submitted to Parallax by Mark L. Hammond SAEBRTrack is the latest incarnation of several projects spanning over 15 years between me, Mark Hammond, N8MH (formerly KC4EBR) and my elder Gene Brigman, KC4SA. SAEBRTrack is a low earth orbit (leo) satellite tracking system. It was originally designed to use inexpensive TV antenna rotators, like the “Orbit 360” sold at many hardware stores. However, I recently modified the code and the hardware to work with the Yaesu G-5500 elevation-azimuth dual controller. The G-5500 certainly is a much better way to go, even with the fairly high price tag. The basis for operation is fairly straightforward. A tracking program (WiSP, Nova for Windows, The Station Program , and DK1TB's SatPC32 program are all known to work) sends data in the EASYCOMM data format out a standard serial port to the SAEBRTrack unit. The Parallax BASIC Stamp 2 decodes the azimuth and elevation information sent by the tracking program, and the array is positioned. While not intended to be used with large antenna arrays, it can handle a standard VHF/UHF setup and even a small dish. This is not a hand holding how-to, but rather an attempt to describe how we built an inexpensive effective system suitable for amateur radio satellite chasing.
