一、引言随着社会经济的不断发展,卫星导航系统应用越来越广泛,为了实现更高的军事效益及经济利益,人们对于设备性能要求也越来越高,但是由于卫星导航系统的特殊性,设备的研制普遍时间长、花费高、不便捷。而卫星信号模拟器则可以为卫星导航系统及各类终端测试提供真实卫星导航系统的高精度模拟,可在受控的实验室环境中为GNSS接收机的研制、测试、生产等环节提供可重复、可选择的测试验证支持。也正鉴于此,人们越来越关注卫星信号模拟源技术的发展。 I. INTRODUCTION With the continuous development of social economy, the application of satellite navigation system is more and more widely. In order to achieve higher military benefits and economic benefits, people are demanding more and more equipment performance. However, due to the particularity of satellite navigation system The development of equipment generally long time, high cost, inconvenient. Satellite signal simulators, on the other hand, provide highly accurate simulations of real-world satellite navigation systems for satellite navigation systems and terminal testing, providing repeatable Optional test validation support. It is also for this reason that people pay more and more attention to the development of satellite signal simulation source technologies.
