Abstract: Aircraft and methods and systems for determining airspeed of an aircraft. The methods and systems allow for calculation of airspeed in near-ground and on-ground aircraft operation. A GPS altitude and a vertical acceleration of the aircraft are obtained for a current time frame. A geometric altitude for the previous time frame is determined, and the difference between the GPS altitude and geometric altitude are combined with the vertical acceleration to calculate a geometric altitude rate of change. The geometric altitude rate of change is used to calculate a pressure altitude rate of change, which is used to calculate a pressure altitude for the aircraft. A static pressure is calculated from the pressure altitude, and the airspeed is calculated using the static pressure.

Abstract: Technologies are described herein for time-synchronizing sample data from independent recording devices utilizing samples tagged from a highly accurate time source. Datasets comprising samples representing a signal over a period of time are received from separate recording devices. A number of samples in each dataset are tagged indicating that the sample was taken immediately after a pulse in a PPS signal from a highly accurate time source onboard the recording device. The indices of the PPS-tagged samples, along with corresponding time values, are extracted from the datasets, and a set of common time values between the datasets is determined. A pair of frames of a specific length are extracted from each dataset aligned on the PPS-tagged samples corresponding to the common time values and comparative analysis is performed on the pair of frames.
