32 Inside GNSS M A R C H / A P R I L 2 0 1 8 ber of last year, and since then we have been testing it in different fields; mari- time, aviation, mining." Romay showed us a "demo" receiver, the key components of which, he said, can actually fit inside a smartphone. "I believe this is the first dual-frequency, multi-constellation SBAS receiver, giv- ing PPP with integrity. Using this in Australia, you can receive the signal through the SBAS satellite, and if you are outside Australia you use the internet to receive the SBAS and PPP corrections." GMV intends to offer two different products: a lower-cost, single-frequen- cy, PPP receiver, equipped with the u-blox M8 chip and delivering 40-50 centimeter accuracy with integrity; and a higher-performance, NovAtel- equipped receiver using GPS, Galileo and GLONASS and capable of achiev- ing around 5 centimeter accuracy with integrity. "Many people at this conference are talking about PPP with integrity," Romay said, "so, here it is, we have a solution that we are ready to bring to market, and it can be integrated with other technologies and sensors." Galileo CS Reverberations ings do appear to be moving on the PPP front. For its part, the European Commission (EC) continued in Munich to defend its recent decision to provide for free a high-accuracy GNSS service, originally conceived as one component of a Galileo fee-based commercial ser- vice (CS). On the industrial side, where a num- ber of companies have already devel- oped and are delivering high-precision positioning for a fee, some wondered out loud whether the Commission's move will undercut their own busi- ness. Of these, President of Hexagon Positioning Intelligence Michael Rit- ter was among the more outspoken. He expressed some confusion as to what "high-accuracy" actually means in the context of the new Galileo service. "We've heard different definitions of what that is – 20 centimeter accuracy? Higher? What convergence time?" he asked. "Because what gives you 20 cen- timeter in one minute gives you one centimeter in five minutes, so there's a lot of ambiguous vocabulary being used right at the moment. Ritter pointed out that existing mar- kets of survey, mapping, agriculture and offshore are already well served by existing European PPP and RTK correction networks and services, and that Hexagon Positioning Intelligence has been providing correction services for three decades. While industry is already working to solve the next chal- lenges of GNSS correction services, he said, the provision of free services will remove or severely diminish the revenue source that industry relies on to rein- vest in research and innovation for the autonomous future. About the Ameri- can companies in the room, he said, "Most of their employees work- ing on PPP are actually in Europe as well. We all need that money to feed our R&D chain a n d t h a t 's w h y o f course we are opposed to that free service. "The reality is the only way we can get to the kind of functional sa fet y a nd i nteg r it y we need, that kind of aut hent ic at ion, t hat kind of accuracy in a short time, which involves not a few but thousands and thousands of refer- ence stations, we need to finance that, or we all sit back and wait 15 years for the government to do it. I'd prefer the EC and GSA would use these funds to speed up the Galileo authentication service." Commission Come-Back In response, European Commission Galileo Commercial Service Manager Ignacio Fernandez-Hernandez said, "We believe that in the long term high accuracy is becoming cheaper and will eventually be free." Hence, the Com- mission's desire to get in front of this inevitable wave. "Some are asking how Galileo high accuracy will affect the industry. But what we are proposing is not compa- rable to an end-to-end guaranteed ser- vice. What we intend to offer stays at the signal level. is relates only to pro- viding better satellite information, bet- ter atmospheric information, which is what satnav providers have been doing for the last decade." Fernandez reminded participants of the steady trend towards increased accuracy even among open GNSS ser- vices available to the general public, and then he said, "You, the industry, are building partnerships and you are evolving your business models. With Galileo high accuracy, maybe some existing services may not be as relevant as before, but there will be other new services. "Our perception is that companies are ready to integrate high accuracy BRUSSELS VIEW European Commission Galileo Commercial Service Manager Ignacio Fernandez-Hernandez Michael Ritter of Hexagon Positioning Intelligence
