Development of Onboard Data Acquisition for Unmanned Air Vehicle Flight Testing

摘要

An off-the-shelf data logger was used as the basis to evolve software andhardware installations providing a simple, reliable data recording system for UAV flight tests. Wiring harnesses, circuit board and plug designs, as well as controlling software were developed for general installations. The recorder is housed in a 4x2.Sxl .5 inch box which can be conveniently installed or removed in any UAV. It is capable of storing up to 512K of data at sampling rates up to 3200 Hz with eight, 12-bit analog channels. A set of MATLAB commands was developed to allow convenient processing and analysis of recorded data. Numerous ground and bench tests were conducted as well as flight tests.
