摘要：
随着基于定位、导航和授时（PNT）信息的产业发展，PNT信息变得日益重要。因此，在GPS失效的场景下，为备份全球定位系统（GPS），各种导航研究被积极开展。利用机会信号（SoOP）进行测距具有基础设施已就位的优势。其中，测距模式（R-Mode）是一种利用可用SoOP（如中频（MF）差分全球导航卫星系统（DGNSS）信号）的技术，该技术近期因其导航潜力而受到认可，目前正处于研究阶段。在本研究中，我们开发了一个信号模拟器，该模拟器考虑了R-Mode中使用的MF DGNSS信号和天波的特性。
英文摘要：
With the development of positioning, navigation, and timing (PNT) information-based industries, PNT information is becoming increasingly important. Therefore, various navigation studies have been actively conducted to back up global positioning system (GPS) in scenarios in which it is disabled. Ranging using signals of opportunity (SoOP) has the advantage of infrastructure already being in place. Among them, the ranging mode (R-Mode) is a technology that uses available SoOPs such as a medium frequency (MF) differential global navigation satellite System (DGNSS) signal that has recently been recognized for its potential for navigation and is currently under research. In this study, we developed a signal simulator that considers the characteristics of MF DGNSS signals and skywaves used in R-Mode.
