GNSS User Technology Report

The GNSS User Technology Report, a sister publication to the GSA’s GNSS Market Report, is published every two years and takes an in-depth look at the latest state-of-the-art GNSS receiver technology, along with providing expert analysis on the trends that will shape the global GNSS landscape in the coming years.

2018 GNSS User Technology Report

The 2018 GNSS User Technology Report begins with a comprehensive overview of GNSS user technology, presenting a summary of recent developments and future trends in GNSS. This section focuses on the multi-constellation and multi-frequency applications that are driving new trends and achieving greater accuracy while maintaining high integrity. Updates on both Global and Regional Navigation Satellite Systems are described in detail Another topical areas are featured, such as s anti-spoofing and anti-jamming trends, and how vulnerabilities can be mitigated. The section concludes with a description of elements that drive innovation, and highlights innovation centres in Europe.

The Report then takes a closer look at how changes in user needs, GNSS systems, and the underlying technologies all impact receiver design. Specific developments and typical solutions for a given application area are also presented, including: Location Based Services, Agriculture, Transportation (Aviation, Maritime, Rail, Road), Surveying and Timing & Synchronisation.

These applications are grouped within three macrosegments:

  • Mass market solutions: presenting high-volume receivers for consumer devices. Automotive (not safety critical), consumer drones, smartphones, and specialised IoT devices from mHealth to robotics are all covered.
  • Transport safety- and liability-critical solutions: presenting receivers built in accordance with standards to deliver such solutions. Automotive, aviation, professional drones, maritime, search and rescue and, new to this issue of the TR, space-borne GNSS applications are all covered.
  • High precision and timing solutions: presenting receivers designed to deliver the highest accuracy (position or time) possible. Agriculture, GIS, Surveying and Timing and Synchronisation applications are all covered.

The Editor´s special section focuses on the important trend of automation, providing both a current overview and a future vision of the trend. This section explains the interconnection between GNSS and automation, shows the benefits of fusion of many different data, and explains why artificial intelligence is not the same as automation. The section mainly focuses on automation trends in road transportation, but also covers trends in the drone and maritime domains.

Finally, the annexes to the Report provide a general overview of GNSS positioning technologies, augmentation services, key performance parameters, and definitions, as well as the methodology used to write the technology report.

The 2018 GNSS User Technology Report was written with the contribution of leading GNSS receiver and chipset manufacturers. Its purpose is to serve as a valuable tool for planning and decision-making in regards to developing, purchasing and using GNSS user technology.
