Newbie..Flying a MISSION and Flying in LOCAL

Hi Guys!!

I got into Pixhawk 1 year back, this is my first time posting a prob… I am new to coding… I use the QGC to do most of the work.

So I am working on this project and I want to fly my Quad using Inertial Navigation, (With local coordinates) WITHOUT GPS… I know it wont be very accurate. But I will be flying only a few feet. I want to run it like a very small mission. I want to know how this is possible.
