摘要
Abstract
Regarding current positioning system cannot improve the passive positioning perform-ance of ground emitter and to achieve high-precision positioning for airborne emitter,a high-pre-cision time-frequency system based on GNSS clock discipline technology is designed,and high-precision synchronization of multi-satellite time-frequency is achieved.On this basis,a four-satel-lite combined location model for high and low orbits satellites is established and simulations are conducted.The simulation results indicate that the combined location technology utilizing the GNSS clock discipline system achieves high positioning accuracy and enables high-precision three-dimensional positioning of airborne targets.This technology has been successfully implemented for LEO-GEO combined positioning,providing valuable experience and reference for further de-velopment.关键词
