Drone with dual altitude hold

DUAL ALTITUDE STABILIZATION

Gyro stabilized drone

Combination of high precision ultrasonic sensor and air pressure sensor enables easy altitude stabilization over various surfaces. Ultrasonic sensor measures distance between the drone and ground with same principle like bats measure distance from obstacles. High precision air pressure (barometer) sensor can detect tiny air changes. This enables to measure height in resolution of 5 centimeters (2 inches).
