Navigating with APM flight controller


I recently purchased an Arducopter flight controller but am still familiarizing myself with its dynamic software. I would like to use it to make an autonomous drone that flies without the use of GPS and is capable of following a falling object using either a camera or radio frequency (RF). However, I would prefer to use RF.

I did see that all of these features are on the Mission Planner but not sure if the follow me mode can do what I need.

Also, would appreciate any tips for a beginner like myself.

Follow mode can follow targets that deliver their latitude, longitude and altitude coordinates.
If you can provide those coordinates, follow mode will do the rest.

Navigating is GPS denied environments is still very hard and prone to multiple errors. Be ready to invest a lot of time reading the documentation, and doing experiments.
