Global Navigation Satellite Systems: Signal Processing and Receiver Architecture

Tutorial summary

The growing need for ubiquitous positioning and navigation to service the anywhere, anytime needs of the consumer location-based services (LBS) and intelligent transport systems (ITS) markets will strongly influence future receiver architectures. In particular, there is a need to operate with a multiplicity of GNSS (Global Navigation Satellite System) systems, but also with other positioning techniques based on wireless communication systems and inertial measurement units. Anywhere, anytime navigation requirements will favor architectures that can deal with a large variety of signal types. Rather than rely on just one signal type for navigation, future receivers will need to scan through the universe of potentially available navigation signal sources and dynamically choose those that are available at its current location and time. It is also common to hybridize GNSS with Inertial Navigation Systems (INS), in order to combine the only short-time stability of an inertial sensor and the longtime stability but noise behavior of a GNSS receiver, taking advantage of their complementary nature. This combination makes possible a reduction of GNSS-noise, bridging of GNSS outages, and even GNSS measurements are also usable when fewer than four satellites are tracked. This envisaged scenario drives the research activities towards innovative signal processing techniques combined with new hardware architectures featuring outstanding electrical performance.

This tutorial provides a systematic overview of fundamentals of global satellite-based navigation systems, including system engineering, orbital mechanics, associated signal processing, and design of navigation receivers, with hybridization with other technologies in mind. The approach covers the whole process of position determination, from the antenna and the Radio Frequency front-end to the digital signal processing, demodulation, data fusion, and the computation of the navigation solution. The tutorial also includes practical guidelines for an effective receiver implementation based on Software Defined Radio technology, and states current hot-topics for research in the area of navigation systems.

The objectives of this tutorial are the following: i) to provide a strong foundation in the engineering of Global Navigation Satellite System (GNSS) signals, receiver processing and system configurations, especially for high-performance applications, ii) to provide a structured view of current and future GNSS signals and to evaluate the signal processing performance of receivers, iii) to describe techniques for the receiver processing of current and future GNSS signals, showing features, capabilities, trade-offs and limitations, and iv) to provide tools and working know-how for the design and implementation of advanced GNSS receivers, including hybridization techniques with other technologies.

The course will benefit both those who need to understand the details and rationale of advanced signal receiver processing and those who need to produce quantitative assessments of receivers and their signal processing performance. Attendees should have familiarity with the fundamentals of communications engineering, along with previous exposure to basic signal processing techniques and terminology.
