GPS Interface for the Raspberry

Mon Oct 15, 2012 9:17 pm

Hi guys,

I'm rather inexperienced at hardware usage and the Raspberry Pi itself (I just bought it days ago). I was thinking about adding a GPS module to the Raspberry Pi for use in a future projects for an automated robotic car to retrieve waypoints and use in navigation and what not. I still have not worked out the details of this project, but I know for sure that I want a GPS module with a great user interface. What do you guys recommend?

I like parralax.com stuff, so maybe their GPS receiver fits the bill.

As usual it has a serial interface, and sends the normal industry standard raw NMEA0183 codes at 9600 baud, but unlike some others theirs can be connected directly to the PI's UART (RxD and TxD) port without any interface stuff (the module works with 3V3 levels).
recommended.

Hi guys,

I'd love to know if you had any success with putting this together. I'm looking into building a basic gps transponder to reflect real-time location data to a Drupal site that I built that maps a fleet of trucks. Any insight into how you've progressed with your projects it is greatly appreciated.

I've a thumbnail "Poundland" bluetooth adapter and bluetooth Holux M-1200 GPS I used to develop with on Symbian S40/S60 and Windows Mobile in the past. I've not tested this combination on the PI but as long as the bluetooth adapter is picked up correctly the serial port on the GPS should also register allowing direct NMEA data reading - this should be another and perhaps easier way of connecting a GPS that shouldn't draw as much PI power.

I got one of the GPS breakout modules from Adafruit -- https://www.adafruit.com/products/746 -- and wired it up with a prototyping plate -- https://www.adafruit.com/products/801. It's quite easy, and works like a charm with GPSd. I chose to connect it to the built in serial port, in lieu of a serial console.

Also worthy of note, the prototyping plate fits perfectly in place of the top piece of the Pi Box -- https://www.adafruit.com/products/859. For something going into trucks, I'm sure you'll want a fully enclosed case :)

That GPS receiver is a champ, too ... it gets a pretty good fix quite fast, even indoors. If there's too much metal for it to work inside your trucks, it has a connector for an external antenna.
