One of the most important skills for autonomous use-cases in outdoor robots is Global Positioning System (GPS) Waypoint Navigation. GPS Waypoint Navigation refers to the ability to give a robot a collection of GPS waypoints (i.e., a set of latitude/longitude coordinates) and have the robot traverse independently from its present location to each of the defined waypoints. Not colliding with obstacles along the way is also desirable.

### Important Aspects of GPS Navigation

Localization and navigation are the two most important aspects of GPS waypoint navigation. Localization is the process of estimating a robot's position using the robot's sensors (such as the UGV wheel encoders, IMU data, and GPS readings). The navigation system is in charge of sending wheel velocity commands to the UGV so that it may move to the target location in this case being a GPS coordinate.
