Hi, I am working on my middle school science project. And we need INS for manipulated variables. However because INS is super expensive ($500). I am just trying to make a simple calculating program with sensors which are already on Navio2 as ublox GNSS receiver, barometer, and IMU. That is how INS works, actually I called calculating program as dead reckoning. Is here any programmer who can just give me some advices?
Please just give me random ideas if you do not know much about INS. It might be helpful!
