[OSM-talk] Build your own GPS receiver

[Andrew Gregory]

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?

Cheers,
Andrew
