Hello, I have a project that requires I fly a drone without the aid of GPS. I would like to use APM Planner or Mission Planner to set waypoints for the drone. However, I’m concerned that both of the flight planners require GPS to be enable on the flight controller in order to use. Can anyone here confirm that these planners do need the GPS or if there are others ways to utilize without using GPS?

You need to get GPS related values to get a global position. You need to have a GPS attached in order to get these values and for the flight controller to calculate where it is in 3d space. So sorry there isn’t a way I know of that allows you to get GPS coordinates without a GPS module. Why aren’t you allowed to use a gps, maybe I can help?
Without GPS you have no positioning in real time. There is a way around it but it is fairly complicated and requires a number of mostly analogue sensors and a lot of mathematics. There are several additional factors that needs to be taken into account such as Gyro drift and such. You also require coordinates from where you launch to have future positions calculated. Why do you want to fly without the GPS, and what kind of accuracy are you looking at?
