Distance measuring equipment (DME) has been a cornerstone of aviation navigation for the last 70 years. While GNSS is taking an increasingly important role in civil aviation, DME can still play an important role in a robust aviation infrastructure in the foreseeable future. Advanced concepts have been developed to improve DME performance and capabilities. One concept is a DME‐based pseudolite that position modulates existing DME pulse pairs. It is interoperable with DME operations and can be generated using the currently fielded DME transponders with an appliqué. This concept is suitable as a robust alternative to GNSS for aviation navigation or timing. The paper examines the performance of DME pseudolite implemented via an appliqué on a DME transponder. The paper examines the synchronization and data performance of the DME pseudolite signal in the air and on the ground. The paper compares the actual performance to theoretical results.

与现有测距设备（DME）地面站兼容的伪距信号的飞行测试

在过去的70年中，距离测量设备（DME）一直是航空导航的基石。尽管GNSS在民用航空中扮演着越来越重要的角色，但DME在可预见的未来仍可以在强大的航空基础设施中发挥重要作用。已经开发出高级概念来改善DME性能和功能。一种概念是基于DME的伪卫星，它可以对现有DME脉冲对进行位置调制。它可以与DME操作互操作，并且可以使用带有贴花的当前现场DME发送应答器生成。该概念适合作为GNSS的健壮替代品用于航空导航或授时。本文研究了通过DME应答器上的贴花实现的DME伪卫星的性能。本文研究了空中和地面DME伪卫星信号的同步和数据性能。本文将实际性能与理论结果进行了比较。
