 The ultimate GPS is a breadboard friendly breakout with built-in data logging, a ceramic patch antenna, as well as a UFL connector for connecting an external antenna. This one is thick so it'll probably be hard to desolder. But I've got my hot air station and a positive attitude. And if those don't work, there's always the mini hot plate. You can see some of the components sloshed around in the molten solder, including the prominent MTK339 GPS chip. It's supported by a 32 kHz crystal, as well as a 16 MHz temperature-controlled crystal oscillator. That center post, of course, is the antenna path. It feeds through an amplifier, then a filter, before entering the GPS chip.
