Hello , I am looking for suggestions preferably based of experience of successful use. One of my projects is an outdoor type, if you have seen the truck like power wheels robot. I would like it to be able to drive to a GPS coordinate then turn until it reaches the next. Also as a secondary feature I would have the outdoor robot follow a person with a orange vest on. It would be nice for the GPS module to be able to plug directly in the ezb as well as capability to update position up to 5 times per second.
Second-
I will also need a compass module I believe to arrange orientation to the vehicle is pointed when it reads GPS so it knows which direction to turn.
Any help is great , direct links to items are what I am looking for.
Keep in mind that even in perfect conditions, GPS accuracy is limited to about 2 meters.
A cell phone which uses aGPS can get that consistently down to about a meter.
There are apps that can turn an Android phone into a Bluetooth GPS, and ARC supports an iPhone app called sensor stream which can stream aGPS position and compass heading over WiFi into ARC variables.
Neither requires a carrier contract to make use if the aGPS function although they do need a sim card for a carrier with local coverage installed to get the assistance data from the nearest cell tower (the sim can be inactive, just needs to be installed).

59.99 , establishes tracking in about 1 second , antenna is embedded.
Thoughts? It says it communicates on 3.3 volt logic so we are good right?
you can search ebay for bargains also for the sensor.

I haven't tried very many of these but I figured this GPS buyers guide from Sparkfun may help:
