Design of an integrated satellite navigation system for guided hypervelocity projectile
An integrated satellite navigation system for guided hypervelocity projectile was designed based on the operating environment and requirements of guided hypervelocity projectile.The integra-ted satellite navigation system was designed in an integrated way.The Connectors were used for con-nection between receiver and antenna and between receiver and control system.The receiver board and low-noise amplifier board were placed inside.The receiver used shielded compartments to reduce the impact of complex electromagnetic environment.The receiver was embedded with polyurethane foam which could effectively alleviate high temperature and impact overload.The radome was made of high temperature resistant polyimide/quartz glass cloth.The antenna array was covered with iron patches.The iterative search range correction method was used to reduce the Doppler search range,which im-proved the acquisition probability of Doppler frequency offset.Simulation and test of the system indi-cate that the system meets the deploying requirements and has strong expansibility and practicability.
