  "text": "The commercial service (hereinafter ‘CS’) offers two major improvements compared to the open service (hereinafter ‘OS’), namely higher accuracy in terms of geolocation (hereinafter ‘CS high accuracy’) and reinforced authentication capacity (hereinafter ‘CS authentication’), which can be offered to users independently of each other. The corresponding technical and operational specifications are set out in the table below:\nCS high accuracy\nCS authentication\nSpecifications common to the OS and the CS: authentication of geolocation information\nSpecifications specific to the CS: authentication using encrypted codes\nGeneral specifications\nSupply of high accuracy data in order to obtain a positioning error of less than two decimetres in nominal conditions of use\nSupply of authentication data for geolocation information from the OS, contained in the signals\nAuthentication of the signals through access to encrypted codes contained in the signals\nComponents of the signals used\nE6, E6-B component for the supply of high accuracy data\nE1, E1-B component for authentication data from the geolocation information\nE6, E6-B component for the access data for encrypted codes and E6-C component (pilot)\nSpecifications of the user segment\nHigh accuracy positioning obtained using precise positioning algorithms integrated into the receiver and using the data transmitted in the signals\nVerification of the authenticity of the data using an asymmetrical cryptography protocol transmitted in the signals and a public cryptographic key\nVerification of the authenticity of the signals by decrypting the codes of the encrypted signals using a private cryptographic key\nGeographical coverage\nGlobal\nGlobal\nGlobal\nSystem architecture\nHigh-accuracy data provided by one or more service providers, transmitted to users via the GNSS Service Centre (GSC), the ground segment and the satellites connected to the ground segment\nAuthentication data inserted into the available capacity of the EDBS field of the E1-B signal component, and disseminated by the satellites connected to the ground segment\nEncryption of the E6 signal codes by the Galileo satellites, transmission of the private keys generated by the ground segment to one or more service providers via the GNSS Service Centre (GSC), and\ntransmission of the OTAR information in the E6-B signal component\nProvision of the service\nHigh accuracy data provided by one or more service providers\nAuthentication data provided by the system established under the Galileo programme\nEncrypted signals supplied by the system operating manager\nAccess to the service\nFree access\nFee-paying access to the encryption codes depending on the pricing policy in force\nAccess to the encryption codes monitored by one or more service providers with the assistance of the system operating manager\nDeployment of the service\nTesting and validation phase to be concluded in 2018\nInitial signals supply phase between 2018 and 2020\nFull service supply phase from 2020\nTesting and validation phase to be concluded in 2018\nInitial signals supply phase between 2018 and 2020\nFull service supply phase from 2020\nTesting and validation phase to be concluded in 2020 at the latest\nCommercial operating phase to begin after that.\nUse of EU classified information\nNo use of EUCI by the Commercial Service Provider or the end user. However, if such authorisation is required it is decided in accordance with the rules on security set out in Article 17(a) of Regulation (EU) No 1285/2013.\nNo use of EUCI by the Commercial Service Provider or the end user. However, if such authorisation is required it is decided in accordance with the rules on security set out in Article 17(a) of Regulation (EU) No 1285/2013.\nNo use of EUCI by the Commercial Service Provider or the end user. However, if such authorisation is required it is decided in accordance with the rules on security set out in Article 17(a) of Regulation (EU) No 1285/2013.\nFurther specifications\nHigh-accuracy data provided for the Galileo satellites and possibly for the satellites of other constellations\nThe transmission of authentication data must not lead to any deterioration in the open service\nThe authentication data must be provided for the Galileo satellites and possibly for the satellites of other constellations\nThe users of the OS accept the risks linked to the use of authentication data\nn/a",
