Full-scale measurement on vibration performance of vehicle-mounted optical transceiver mast

Abstract

Background: Mast is mainly used for assisting the communication-vehicle-mounted optical transceiver to obtain a coarse tracking of objects rapidly and accurately, especially when objects are communicating among different regions. Methods: This study first conducts a force analysis of a vehicle-mounted mast specialized for laser communication and then derives dynamic characteristics of the mast under wind load. In order to validate tracking precision and the stabilization of the optical transceiver, and examine the wind disturbance resistance of the mast, a series of field experiments were carried out. Results and Conclusion: Finally, the test errors were analyzed in detail, and the experimental results demonstrated that the tracking error of the vehicle-mounted optical transceiver is less than 80μrad which means the optical transceiver satisfies the system requirements in terms of precision. Furthermore, both theoretical analysis and experimental results revealed that designed mast satisfies the technical requirements of the vehicle-mounted laser communication, thus the feasibility of the mast in vehicle-mounted communication was validated.
