Positioning Using IRIDIUM Satellite Signals of Opportunity in Weak Signal Environment
electronics Article Positioning Using IRIDIUM Satellite Signals of Opportunity in Weak Signal Environment Zizhong Tan, Honglei Qin, Li Cong * and Chao Zhao School of Electronic and Information Engineering, Beihang University (BUAA), Beijing 100191, China; [email protected] (Z.T.); [email protected] (H.Q.); [email protected] (C.Z.) * Correspondence: [email protected]; Tel.: +86-1381-0629-638 Received: 9 December 2019; Accepted: 25 December 2019; Published: 27 December 2019 Abstract: In order to get rid of the dependence of the navigation and positioning system on the global navigation satellite system (GNSS), radio, television, satellite, and other signals of opportunity (SOPs) can be used to achieve receiver positioning. The space-based SOPs based on satellites offer better coverage and availability than ground-based SOPs. Based on the related research of Iridium SOPs positioning in the open environment, this paper mainly focuses on the occluded environment and studies the Iridium SOPs positioning technique in weak signal environment. A new quadratic square accumulating instantaneous Doppler estimation algorithm (QSA-IDE) is proposed after analysing the orbit and signal characteristics of the Iridium satellite. The new method can improve the ability of the Iridium weak signal Doppler estimation. The theoretical analysis and positioning results based on real signal data show that the positioning based on Iridium SOPs can be realized in a weak signal environment. The research broadens the applicable environment of the Iridium SOPs positioning, thereby improving the availability and continuity of its positioning. Keywords: signals of opportunity positioning; Iridium; weak signal; instantaneous Doppler 1. Introduction The new methods for receiver positioning based on abundant and various frequency signals have emerged in recent years. -

ABSTRACT United Kingdom’s Brexit from the European Union implies restricted access to the European Global Navigation Satellite System (GNSS) System - Galileo; with no access to the secured and encrypted signal used for defense and government purposes, which is restricted to European Union (EU) members. To mitigate this issue, the United Kingdom can, as a matter of urgency, launch a payload on a national military Communications Satellite to provide Navigation Overlay Services for the United Kingdom territory, surrounding waters and neighboring ally countries to meet the requirements of: Defense systems, Aviation, Maritime requirements and the effectiveness of Location-based Services for Emergencies and Crisis management etc. This paper describes the design of a navigation overlay service system as a hoisted payload on a national satellite and the required supporting ground infrastructure, highlighting various applications, services and solutions. Keywords: Brexit, Communications Satellite, Defence, European Union (EU), Galileo, GNSS, Military, Precision Point Positioning, SBAS. 1 INTRODUCTION TO GLOBAL NAVIGATION SATELLITE SYSTEM (GNSS) The United States Global Positioning System (GPS) marked the beginning of Global Navigation Satellite Systems (GNSS). After the First World War, radio time signals offered alternative technology for determination of the Greenwich Time line and thus longitude at sea. -

1 Introduction 1.1 Scope The past two decades have seen a quiet revolution in satellite-based services. Once the preserve of governments, international bodies, public utilities and large corporations, today the majority of satellite service users are individuals, who can now access, directly, a wide range of satellite services – typically using personal, mass-market and even handheld devices. These satellite systems now fulfil a variety of personal necessities and aspirations spanning telecommunications, broadcast services, navigation, distress and safety services and (indirectly) remote sensing, in the commercial, military and amateur sectors. It therefore seems an appropriate time for a book that addresses these services from the perspective of their support for, and functionality delivered to, individual users. This book therefore aims to: • enhance awareness regarding the expanding role of satellite systems in individuals’ daily lives; • lay a strong technical foundation of the basic principles and functioning of these satellite systems for personal communications, navigation, broadcasting and sensing applications; • illustrate current practice using selected example systems in each field; • review current trends in relevant satellite and related technology. The book aims to address an audience that is inquisitive and keen to understand the role of satellites in our daily lives and the underpinning concepts, and, in contrast to alternative offerings, the focus in this book is on the individual and the end-user application. It aims to provide all of the relevant concepts, in a clear and concise manner, together with descriptions of key systems as illustrations of their implementation in practice. Satellite services are formally categorized by the International Telecommunications Union (ITU) according to their broad service types. -
