The GPS module they're using is based on the MK3339, which I'm currently using in a commercial project. Very low power consumption and amazing performance.
However, in terms of making your own receiver, I don't see the point unless it is for an extremely specialized task. The reason is cost. The GPS breakout board is ~$40. A Raspberry Pi is ~$35. That's already ~$75. Shipping not included. I can buy a GPS-enabled Android phone for ~$50. In my local supermarket! I could probably get something cheaper on ebay. So, for $25 less than the GPS+Pi I also get: battery operation, a touch-enabled colour screen, 5MP camera, Wi-Fi, 2G/3G mobile voice/data, Bluetooth, and easy USB connectivity to a PC. I'll probably also get a micro-SD slot. It's all down to your application. What do you want to do that you can't do on a $50 smartphone?
