摘要: The drone has a telemetric sensor (154) that is ready to consider distance relative separation of the from surface echoes returning ultrasonic impulses emitted by drone. An altitude determination unit (134) includes barometric (156), and an estimator (152). obstacle detecting analyzes deduce presence configuration applies corrective action compensate effect at estimated sensor.
