Title Aircraft data link antenna pointing control system design
Abstract
Aircraft data link antenna pointing control system design, this paper discusses the orbit TDRS spacecraft space-based data link solver, simulation using STK chain One day our country relay communication systems, simulation of Tianlian to close spacecraft coverage and visibility; discuss research from the perspective of the overall application conformal phased array antenna in space-based data link communications, discusses the Ka / S-band antenna working process between the aircraft and relay satellites, analysis the point from the program to automatically track the work process; studied in a motor vehicle how to accurately point to relay satellite, narrative and aircraft attitude coupled algorithms and understanding between the operator; article concludes with a discussion of the use of embedded systems with ARM hardware design simulation platform to verify the correctness of theoretical analysis, while discussing the treatment equation optimizing embedded systems with limited ability solver this situation so that the antenna design theory has been supported by experiments.
