> autonomous flight (GPS) through an interface that can be installed on an Android tablet. In case of jamming, the flight continues because the drone can locate itself according to its speed and direction. In case anyone is wondering how that works, it uses on-board IMS (Inertial Navigation System) in the absence of GNSS signal, which usually has several sensors like accelerometers (to measure motion in 3D directions) gyro (to stabilize pitch roll yaw drift) and magnetometer (compass for yaw direction), these sensors will provide the drone pointing directions and how long it moved since it started, couple this with on board maps and you have a flight with no GNSS. Is it accurate like GNSS? Not cm or even meters level, but that depends on how good the IMS is. Also, you can have plenty of these cardboard models, or even 3D printable one of you are into this hobby!
