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.

Sending NMEA Commands via Direct Connect

You can send $PMTK and other commands from the GPS module datasheet, just type into the

serial monitor box. Don't forget you'll need to set Both NL & CR (new line and carriage return) next

to the baud rate selection box)!

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

first three characters are the degrees.)
