High Precision GNSS - What will it Look Like in 2020?

In September, I attended the Institute of Navigation (ION) GNSS+ conference in Tampa, Florida. The ION GNSS+ conference is a gathering where many of the GNSS scientists from around the world come to share their successes, trials and tribulations. It gives one a view into the future of where GNSS positioning might go. Granted, most of the ideas and concepts... read more

A Hansel and Gretel Approach to Cooperative Vehicle Positioning
Several technologies are being developed for accurate cooperative vehicle positioning, but GNSS also has a role to play. In this month’s column, team of British researchers turn to a children’s fairy tale for inspiration in their development of a cooperative vehicle positioning approach using carrier-phase observations — another innovative application of real-time kinematic or RTK GNSS technology. read more

Emerging GNSS applications in automobiles support regulation, security, safety, and financial transactions, as well as navigation, guidance, traffic information, and entertainment. The GNSS sub-systems and onboard applications must demonstrate robustness under a range of environments and varying threats. A dedicated automotive GNSS test center enables engineers to design their own GNSS test scenarios including urban canyons, tunnels, and jamming sources at a controlled test site. read more

Network RTK for Intelligent Vehicles

February 1, 2013By

Adoption of network real-time kinematic GNSS positioning can lead to major improvements in vehicle localization, although implementation must overcome some real-world challenges. This article assesses the extent of GNSS signal outage in a motorway environment. The average total GNSS outage period and the average time to resolve ambiguity for the network RTK solution can help assess complimentary sensors for a ubiquitous positioning system. read more
