European Union Global Navigation Satellite System (GNSS) has begun the delivery of its High Accuracy Service (HAS), officially announced by Thierry Breton, European Commissioner for Internal Market, “feeding a prosperous market for innovative applications – from farming to drone navigation and autonomous driving.”
Galileo is now the first Global Navigation Satellite System (GNSS) providing free-of-charge, high accuracy Precise Point Positioning (PPP) corrections worldwide both through the Galileo signal in space (E6-B) and via the internet.
The precise corrections provided by the Galileo HAS will allow users to improve the accuracy associated with the orbit, clocks and biases provided through the Galileo Open Service broadcast navigation messages and the GPS Standard Positioning Service navigation data. These corrections enable the computation of a high accuracy positioning solution in real-time when processed by an appropriate algorithm in the users’ receivers tracking the Galileo E6-B signal.
The typical accuracy below a few decimetres (<25cm horizontal) in nominal conditions of use is a revolution where Europe provides this as an integrated service for free, thus allowing the massive development of applications worldwide.
Following the HAS Initial Service Declaration, the Galileo Programme will continue its efforts to incrementally improve its coverage and performance over the next years towards its Full-Service Declaration.
Executive Director, Rodrigo da Costa said “Galileo HAS will become the pillar of many EU sectorial policies. Currently, high accuracy is primarily used in such professional applications as surveying, precision agriculture and civil engineering, amongst others,” he says. “However, new and emerging applications, including autonomous driving, unmanned vehicles, robotics and a range of location-based services will all welcome high accuracy.”
Da Costa also notes that, when used in synergy with Copernicus, the Galileo HAS will open up new market possibilities and help design new services.
All official HAS documentation, including its Service Definition Document (SDD) are available in the European GNSS Service Center (E-GSC), managed by EUSPA.
