Today I would like to present you a small GPS module with super capacitor backup. Having GPS coordinates known during flight time is very beneficial. There are multiple ways in which longitude and latitude can be used to enhance the RC flight experience. Once again we have, and for the most obvious reason, the ability to track a plane or a drone. We can also calculate the current distance to a flying object in line of sight. Finally, using GPS coordinates, it is possible to implement an autopilot and a feature called return to home in case of broken radio link.
