A person who decides to buy a sports car values certain things; they want the engine, they want the speed, the maneuverability. Somebody who has an armored car, it's still a vehicle, but they value the security. ey've probably given something up in terms of driving performance, but it's because safety is their priority." It's the same with GNSS receivers, she suggested. "Which of the parameters are most important for a particular user and why do they choose one or the other? We've heard about having a very quick time to first fix, when you drive out of a parking garage and want a solution instantly. Well you can get that but you're going to have to wait some time before that's an authenticated or verified solution – or you might not be able to run your RTK (real-time kinematic) solution at faster than 20 hertz, or we might not be able to track every single satellite in view, and so on." Are users ultimately going to have to choose a level of vulnerability they are willing to accept? "It really depends on your perception of risk," Kennedy said. "What we are work- ing on is what level of protection can be provided by default in the background without causing any compromises to per- formance. How much CPU (central processing unit) can we be using to run a bunch of interconstellation and intersignal checks and that sort of thing. "Right now what we are seeing is customers that can articu- late very clear needs in terms of accuracy levels in this many seconds, but we don't have that kind of specific definition by customers in terms of interference detection." And why is that?, someone interjects. "I think people just don't know." Bingo. So there's an education process that still needs to take place. Kennedy borrows from an old Canadian TV comedy sketch: "GNSS users, you need to know what you need to be afraid of!" Money, Honey But really, what about that funding? Between 2014 and 2020, the GSA's Reinhard "e Candyman" Blasi said, altogether 111.5 million Euro (approximately $138 million) will have been invested by the GSA, at the behest of the EC. is is mainly for Horizon 2020 Fundamental Elements projects, aimed at developing the likes of EGNOS and Galileo-enabled chipsets, receivers and user terminals. "We want to build on innovative services and differentia- tors," he said, "while addressing real user needs and maximiz- ing the benefits for EU citizens." One of the key stated aims of all H2020 funding has been to increase industrial competitiveness within the EU, which means the program prioritizes EU participation, but parties from third countries can get funding under certain conditions. Upcoming 2018 and 2019 grants, not yet awarded, will go to projects aimed at developing Galileo-based timing receiv- ers, CS user terminals and enhanced GNSS user terminals. So, there you have it.
