GPS is definitely one of the most handy sensors you can add to your project - it can provide you with a whole host of data including things like location, altitude, speed, heading, and more. We already have a GPS Buying Guide that will help you decide which unit is good for you as you sort through our GPS category, but you might want a little more.
For a more in-depth look at the GPS units we offer, check out Engineer Aaron's "GPS Tracking Comparison." This tutorial shows the type of readings you can expect from your GPS and goes through the pros and cons of each unit.
So whether you are looking to build an autonomous robot or create a hand-held GPS unit for geocaching adventures, this tutorial can help you better understand GPS and how to implement it into your next project!
