| Abstract: |
| Fully automatic landing is a key means to ensure the safety of carrier based aircraft landing and improve the dispatch rate.The authors analyze the development and application of fully automatic landing guidance and transmission systems for foreign carrier based aircraft,study the application requirements of moving bases and complex electromagnetic environments for offshore carriers,break through the high-precision measurement of satellite navigation under anti-interference conditions,differential relative positioning of dynamic reference,low delay and high reliability transmission,and propose a comprehensive solution for fully automatic precision approach guidance and transmission systems.Through prototype system development and testing verification in typical environments,the feasibility of the principle is verified,and the relative positioning accuracy of the prototype system in dual dynamic states reaches the decimeter level,the transmission time can reach the millimeter level,corresponding to the foreign technical level.The research and conclusions provide important reference for the development of equipment related to unmanned aerial vehicle takeoff,landing,and automatic landing of carrier based aircraft. |
