If you can get your hands on a Rand McNally GPS this Rand McNally GPS Hack will show you how to get the serial data out of it. Since these GPS devices are quite old now they should be quite cheap. Does anyone know of a cheaper serial GPS solution? If so please share it with me. |

A used one of those should be nice and cheap.

I recently picked up a pile of USGlobalSat GPS units for $25 each, from their eBay outlet store. These were brand new in the box, SiRF-II chipset units, with WAAS enabled and USB adapters included. (If you omit the adapter, it’s NMEA 0183 data at TTL levels on a PS/2 style Mini-DIN connector.) They appear to have some more up right now:

Any SiRF GPS owners should check out the SiRF Demo app, which lets you configure the output sentence structure and rate, configure input if you’re using a separate DGPS receiver, download and upload raw ephemeris data tables, and otherwise muck with the innards. http://www.sirf.com/free_demo.html

I picked up a Talon GPS today at a yard sale. It’s the Rand McNally receiver that you wrote about… I paid a single buck for it. Will make a great addition to my APRS project box.
