INTRODUCTION
HOW TO READ THIS REPORT
The GNSS User Technology Report is a continuously evolving publication that builds upon a similar structure and format used in previous issues.
This third issue of the GNSS User Technology Report is therefore structured into the following blocks:
The opening section, GNSS User Technology Overview, presents a summary of recent developments and future trends in GNSS. Updates on
Galileo, GPS, GLONASS, BeiDou and Regional Navigation Satellite Systems are described in detail as well as latest developments in the area of
GNSS augmentation. The chapter also gives a status update on multi-constellation and multi-frequency adoption in receivers. It presents different
position processing methods and the latest innovations in signal processing and antenna technologies expected to deliver more accurate, less
energy-hungry and more reliable PNT services. Specific focus is made on PNT vulnerabilities that affect GNSS and beyond. Relevant measures and
means to get protected against the growing jamming and spoofing threats to GNSS are introduced. The chapter concludes with a description of
EU GNSS downstream R&D programmes and examples of innovative technologies from members of Galileo Services organisation.
The second part of the report consists of four sub-sections where technology solutions and their use cases are presented, grouped into four
macrosegments.
High-volume devices – presenting devices (meaning chipsets, modules and receivers) manufactured in very large quantities primarily for con-
sumer devices. Automotive (not safety critical), drones (limited to ‘open’ category according to EASA categorisation), smartphones and specialised
IoT devices from mHealth to robotics are all covered.
Safety- and liability-critical devices – presenting devices built in accordance with standards to deliver such solutions. Automotive, rail, aviation,
drones (others not belonging to the ‘open’ category according to EASA categorisation), maritime and search and rescue solutions are all covered.
High-accuracy devices – presenting devices designed to deliver the highest accuracy (position or time) possible. Agriculture, surveying, mining,
GIS solutions are all covered.
Timing devices – presenting devices delivering time and synchronisation solutions for the telecom, energy, finance or transport sectors.
In this issue, the Editor´s special focuses on Space Data for Europe, and the role of flagship European Space Programmes, Copernicus and Gali-
leo. It also provides a vision of major transformations underway within our society and our economy and the benefits that are expected from this
digital transformation, including the enablement of the European Data Strategy and Green Deal. The Editor explores the various technologies
involved in the exploitation of this massive amount of data, as well as the challenges to fit with and exploit the full potential of up-coming digital
age that lay ahead.
Finally, annexes close the report with a general overview of GNSS constellations and frequencies (Annex 1), augmentation systems (Annex 2), the
definition of key performance parameters (Annex 3), a summary of radio-frequency interference threats to GNSS (Annex 4), the list of acronyms
(Annex 5), the methodology used to write this technology report (Annex 6) and information about the authors (Annex 7).
