GNSS technology is changing the way we live, work and move. Whether it’s getting from point A to point B by land, sea or air, travelling through remote areas or navigating the concrete jungles of a congested city, GNSS technology is there. In fact, with mobile phones already incorporating global positioning receivers as standard equipment, we now have unprecedented access to precise positioning information – no matter where in the world we are.
Because of this diversity in uses, user requirements for GNSS applications vary in terms of availability, accuracy, continuity, integrity or robustness to spoofing and jamming. The European GNSS Systems EGNOS and Galileo meet the varying needs of these different user communities in the following way:
|User Groups of||Mass market consumer applications||Workforce, fleet, traffic and asset management||Liability-critical application||Safety-critical applications||High-precision applications||Timing applications for financial services, energy and telecom|
|Relevant Market Segments||LBS, road, VFR general aviation, maritime (leisure boats navigation), rail (passenger information)||LBS, road, rail and agriculture (farm and livestock management)||Road (tolling operators, insurance telematics), LBS (mobile payments), maritime (fisheries, marine park management)||Aviation, road, LBS (emergency caller location), rail and maritime||Agriculture and surveying||Timing and synchronisation|
|EGNOS||Accuracy, especially in remote areas||Accuracy, sometimes integrity||Integrity, accuracy||Integrity, accuracy, compliance with safety requirements and standards||Accuracy||Potentially improved quality of synchronisation|
|Galileo||Availability, better resistance to multipath, accuracy, time to first fix (TTFF)||Availability, better resistance to mutipath, accuracy, TTFF, authentication||Authentication, availability, accuracy, continuity||Availability, accuracy, compliance with safety requirements and standards, dedicated SAR service with return link||Accuracy, availability, TTFF||Accurate time, authentication|
