Commercial Service for Galileo
Galileo Commercial Service will provide an additional navigation signal and added-value services on a different frequency.
The European Commission and the European GNSS Agency (GSA) have confirmed that the first generation of Galileo satellites will provide users with 'High Accuracy' and 'Authentication' services. The 'Commercial Service' (CS) will complement the Galileo Open Service (OS) by providing an additional navigation signal and added-value services on a different frequency. Unlike the OS, the CS signal can be encrypted to control access.
GSA Executive Director, Carlo des Dorides, comments: 'The Commercial Service is unique in that its services are not provided by any other GNSS programme and thus represents a unique opportunity for Galileo to differentiate itself from other systems, and offer users an added value to the standard positioning services already available.'
the Commercial Service will provide:
- a High Accuracy service based on the transmission of Precise Point Positioning (PPP) information through its E6-B signal, delivering accuracy below one decimetre worldwide.
- a Commercial Authentication service based on E6 signal code encryption, allowing for increased robustness of professional applications.
The user community will also be able to use the Open Service Navigation Message Authentication (OS NMA) free-of-charge. This is capable of protecting users from spoofing attacks by digitally signing the normal OS message in the E1 band.
The CS will be provided at a charge - but at least one signal component of the E6 signals will be freely available, allowing user communities to benefit from signals in all Galileo bands. The CS will be operated by at least one yet-to-be-determined commercial service provider. All services are compatible with the current signal definition and are based on existing infrastructure.
After testing, the CS will become available when Galileo reaches Full Operational Capability (FOC) - expected by 2020. It will complement the OS, Public Regulated Service (PRS) and Search and Rescue (SAR) service - all available now via the Galileo Initial Services. Additional satellites will be successively added to the constellation, with the launch of the next 4 scheduled in 2017.
