Satellite interference geolocation plays a critical role in addressing radio interference problems related to satellite communications systems. Traditional interference geolocation approaches are mainly based on time-difference-of-arrival (TDOA) and frequency-difference-of-arrival (FDOA) measurements. However, since new technologies have appeared, such as the widespread use of high-frequency bands, spot beams, emerging large-scale low- Earth orbit satellite constellations, and onboard processing, traditional methods may be unsuitable for modern satellite communications. Currently, to overcome these challenges, new approaches, such as single-satellite geolocation, geolocation onboard, and geolocation using carrier identification (CID), have been investigated in the literature. In this article, we provide an overview of the principles of, and innovations involving, interference geolocation techniques in satellite communications. In addition, we present the fundamental constraints, key challenges, and future directions for performing geolocation.

卫星通信系统中的干扰地理定位：概述

卫星干扰地理定位在解决与卫星通信系统有关的无线电干扰问题中起着至关重要的作用。传统的干扰地理定位方法主要基于到达时间差（TDOA）和到达频率差（FDOA）测量。但是，由于出现了新技术，例如高频带的广泛使用，点波束，新兴的大规模低地球轨道卫星星座以及机载处理，因此传统方法可能不适用于现代卫星通信。当前，为了克服这些挑战，文献中已经研究了新方法，例如单卫星地理定位，机载地理定位和使用载波识别（CID）的地理定位。在本文中，我们概述了以下原则，以及涉及卫星通信中干扰地理定位技术的创新。此外，我们介绍了进行地理定位的基本限制，关键挑战和未来方向。
