Space application and test design of dual-comb ranging technique
摘要
Abstract
The dual-comb ranging technique has the advantages of high precision,fast response speed,large unambiguity range and on-site traceability.It has broad applications in space missions,such as spacecraft rendezvous and docking,satellites formation-flying,positioning of large deployment mechanisms.Under the scenario of rendezvous and docking between cargo spacecraft and space station,a space application and test scheme of high-precision dual-comb ranging was proposed.Firstly,basic theory of dual-comb ranging was introduced,and the architecture of the test system was built.It is theoretically demonstrated that a precision of 100pm in the range of 400m,along with a 1 kHz response speed,can be achieved.Further,the key parameters of the ranging system were designed and simulated,and the space environment adaptability of the system was analyzed.The results show that it can achieve high-precision measurement within a maximum speed of 19.5 m/s,meeting the mission requirements.The analysis results provide a technical reference for the on-orbit test and aerospace engineering application.关键词
