摘要
Abstract
Based on the theory and signal transmitting characteristics of GPS and Loran-C, considering the curvature of the earth, atmosphere refraction, electromagnetism attenuation, and earth-wave loss and other factors, study the effect of 2 kinds of navigation system with high power jamming machine. Introduce GPS system and Loran C system, by calculating the minimum interference power of the GPS receiver, and the interference distance of the GPS receiver, the model of the GPS interference machine is analyzed, at the same time, study on the effect of Loran C interference model, and 2 kinds of systems are analyzed. The results show that under the same interference distance, to achieve the same effect of interference, the interference power of Loran-C is much larger than GPS system; therefore, Loran-C working as a backup of GPS can help to solve the problem of poor anti-inference ability of GPS to some extent.关键词
