You can make your drone follow you if you use a smartphone. Your smartphone already has a built-in GPS, and the drone will follow your phone if properly configured. You will need an OTG connector to connect the telemetry to your phone. Wherever you take your phone, your drone will follow it, as long as the data transmission is good. You can use any of the following two applications (there might be other applications that I have not tested) for this:

• DroidPlanner2
• Tower

Unfortunately, neither of the applications is available for iPhone (there is the 3DR Solo application for iPhone that can be used to control the on-drone camera by using Wi-Fi and Sidepilot, which is able to configure the drone to Follow Me mode if you use the ArduCopter or 3DR Solo platforms). So, we need to use Android phones. Let's learn how you can configure your drone with your smartphone. Firstly, we will learn how you can configure by using the DroidPlanner 2 application.
