Abstract

: Positioning is very important worldwide in several fields, and it can be deter-mined by several ways. The most popular ways are Global Navigation Satellite System (GNSS) and Inertial Navigation Systems (INS). Both techniques have advantages and disadvantages. Accurate positioning is one of the privileges of GNSS, while INS overtops in indoor places, despite low accuracy after long duration. Sensibility to interference and multipath are the principal downsides of GNSS structure, which might be the two primary assets of mistakes in position estimations. The main impact of interference at (GNSS) receiver, consequently dropping its cap potential to navigate, is that it lessens the signal to noise ratio (SNR) of navigational signal such that the receiver is not able to reap measure-ments from the satellite. A comprehensive survey of interference suppression methods is presented in this paper and the interference suppression techniques are compared. Two new recommended filter designs to detect spoofing and optimize acquisition in the presence of interference are proposed.

GNSS干扰抑制技术综述

定位在世界范围内的许多领域都是非常重要的，它可以通过几种方法来确定。最常用的方法是全球导航卫星系统(GNSS)和惯性导航系统(INS)。这两种技术各有优缺点。准确定位是GNSS的优势之一，而INS在室内位置占优，尽管长时间使用精度较低。对干扰的敏感性和多径是GNSS结构的主要缺点，这可能是位置估计错误的两个主要资产。干扰对(GNSS)接收机的主要影响是降低导航信号的信噪比(SNR)，从而使接收机无法从卫星获得测量值。本文对干扰抑制方法进行了综述，并对各种干扰抑制技术进行了比较。提出了两种新的推荐滤波器设计，用于检测欺骗和优化干扰下的采集。

期刊介绍： The International Journal of Interdisciplinary Telecommunications and Networking (IJITN) examines timely and important telecommunications and networking issues, problems, and solutions from a multidimensional, interdisciplinary perspective for researchers and practitioners. IJITN emphasizes the cross-disciplinary viewpoints of electrical engineering, computer science, information technology, operations research, business administration, economics, sociology, and law. The journal publishes theoretical and empirical research findings, case studies, and surveys, as well as the opinions of leaders and experts in the field. The journal''s coverage of telecommunications and networking is broad, ranging from cutting edge research to practical implementations. Published articles must be from an interdisciplinary, rather than a narrow, discipline-specific viewpoint. The context may be industry-wide, organizational, individual user, or societal. Topics Covered: -Emerging telecommunications and networking technologies -Global telecommunications industry business modeling and analysis -Network management and security -New telecommunications applications, products, and services -Social and societal aspects of telecommunications and networking -Standards and standardization issues for telecommunications and networking -Strategic telecommunications management -Telecommunications and networking cultural issues and education -Telecommunications and networking hardware and software design -Telecommunications investments and new ventures -Telecommunications network modeling and design -Telecommunications regulation and policy issues -Telecommunications systems economics
