Welcoming the adoption of the Galileo Commercial Service Implementing Decision, the European Commission and the GSA has confirmed that the first generation of Galileo will provide users with High Accuracy and Authentication services. The Commercial Service will complement the Galileo Open Service by providing an additional navigation signal and added-value services in a different frequency band. Unlike the Open Service, the Commercial Service signal can be encrypted in order to control access to Galileo Commercial Services.
Following the Commercial Service Implementing Decision, the user community will also be able to use the Open Service Navigation Message Authentication (OS NMA) for free. The OS NMA is capable of protecting users from spoofing attacks by digitally signing the Open Service message in the E1 band.
To avoid disrupting existing professional markets, it is planned that the Commercial Service will be operated by at least one yet-to-be-determined commercial service provider. All three services are compatible with the current signal definition and are based on existing infrastructure.
After a test period, the Galileo Commercial Service will become available when Galileo reaches Full Operational Capability (FOC), which is expected by 2020. It will complement the Galileo Open Service, Public Regulated Service (PRS) and Search and Rescue (SAR) service. Additional satellites will be successively added to the constellation, with the launch of the next four foreseen in 2017.
