Datasheet

The next data is the ground speed in knots. We're going 2.03 knots

After that is the tracking angle, this is meant to approximate what 'compass' direction we're heading at based on our

past travel

The one after that is 160412 which is the current date (16th of April, 2012).

Finally there is the *XX data which is used as a data transfer checksum

Once you get a fix using your GPS module, verify your location with google maps (or some other mapping software).

Remember that GPS is often only accurate to 5-10 meters and worse if you're indoors or surrounded by tall buildings.

People often get confused because the GPS is working but is "5 miles off" - this is because they are not

parsing the lat/long data correctly. Despite appearances, the geolocation data is NOT in decimal degrees. It

is in degrees and minutes in the following format: Latitude: DDMM.MMMM (The first two characters are the

degrees.) Longitude: DDDMM.MMMM (The first three characters are the degrees.)
