在许多情况下，全球导航卫星系统（GNSS）（例如全球定位系统（GPS））无法提供足够的导航性能（例如室内或城市峡谷中）。本文介绍了非全球导航卫星系统射频导航的技术挑战，特别强调机会信号（即，用于导航以外目的的信号）。机会导航信号的优点和缺点，沿着的主要问题，必须处理，以使这种系统成为现实。
There are many situations in which global navigation satellite systems (GNSS) such as the global positioning system (GPS) cannot provide adequate navigation performance (such as indoors or in urban canyons). This paper describes the technical challenges of non-GNSS radio frequency navigation, with particular emphasis on signals of opportunity (i.e., signals that are intended for purposes other than navigation). Advantages and disadvantages of signal of opportunity navigation are described, along with the dominant issues that must be dealt with in order to make such systems a practical reality.
