摘要： Systems and methods to protect the flight envelope in both manual flight and flight by a commercial autopilot are provided. A system can comprise: an inertial measurement unit (IMU); a computing device in data communication with the IMU; an application executable by the computing device comprising: logic that estimates an angle of attack; a slip angle; and a speed of an unmanned aerial vehicle (UAV) based at least in part on data received from the UAV. A method can comprise estimating, via a computing device, flight data of a UAV based at least in part on data received from an IMU; comparing the estimated flight data with measured flight data; and triggering an error indication in response to a determination that the measured flight data exceeds a predefined deviation of the estimated flight data. The estimated speed can comprise an estimated airspeed, vertical speed and/or ground velocity.

摘要： A weather measurement system can include an aerial vehicle. An array of accelerometers can be disposed across the surface of the aerial vehicle. The accelerometers can be configured to measure raindrops impacting the surface. The measurements can include number per unit time and intensity. The system can include a processing unit configured to receive measurement data from the array and to process the measurement data into preprocessed data.
