A Barometer measures the pressure in the air, which help the Phantom know its altitude above the ground.ģ. Advanced models such as the Phantom 3 Pro read both USA (GPS) and Russian (GLONASS) satellites, resulting in much more accurate positioning than previous models.Ģ. The GPS gathers satellite data in order to determine the position of the Drone – this data is also fed into the main flight controller. Multirotor Flight Control Sensors and Instruments Modern Camera Drone Sensorsġ. Keeping the drone AND the camera steady and under control results in the desired end – butter smooth video and stunning photographs. Radio Control between the ground and the drone. Modern camera quadcopters, such as the Phantom 3 or Phantom 4 series, need to have control of multiple systems: It is only the combination of these sensors (sensor fusion) and the proper programming which makes the system function as intended. Based on the slippage of the tires, the steering angle and other such inputs, the anti-lock systems makes decisions which help your car stay on the road. Most modern automobiles have anti-lock brakes which use various sensors and computers to acheive a better result than a human driver would. Some fancy words…for sure! An example might help. “combining of sensory data or data derived from disparate sources such that the resulting information has less uncertainty than would be possible when these sources were used individually.” For our more logical minds, it may help to rename magic to “sensor fusion” which is defined as:
