Testing GNSS High Accuracy and Authentication
In the near future, the Galileo program will decide on the design and implementation of a Commercial Service for civil applications that provides high-accuracy positioning and signal authentication. A team of authors involved in the program describes the evolution of this service, its current design, and the results of tests of its capabilities using actual signals in space.
“There is no boundary between my work and non-work life,” says this South African engineer, “I love what I do and do what I love.”
Some Aspects of EGNOS Performance in Ukraine
Although the European Geostationary Navigation Overlay Service is primarily designed to provide benefits from a space-based augmentation system that serves the European Union nations, it actu¬ally covers regions outside that geographic area. Researchers tracking EGNOS signal availability in Ukraine conclude that its performance there is improving in robustness and reliability.
“It is incumbent upon us as part of our policy of promoting interoperability and compatibility that we not put up artificial restrictions to foreign systems in the U.S. lest other people try to do the same to us.”
GNSS Authentication for Modernized Signals
The problem of GNSS signal authentication is drawing ever more attention to the potential risk of “spoofing” attacks and the need to develop methods for verifying the authenticity of GNSS signals.GNSS Authentication for Modernized Signals
