ANNEX

Technical and operational specifications allowing the commercial service offered by the system established under the Galileo programme to fulfil the function referred to in Article 2(4)(c) of Regulation (EU) No 1285/2013

The commercial service (hereinafter ‘CS’) offers two major improvements compared to the open service (hereinafter ‘OS’), namely higher precision in terms of geolocation (hereinafter ‘CS high precision’) 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:

CS high precision

CS authentication

Specifications common to the OS and the CS: authentication of geolocation information

Specifications specific to the CS: authentication using encrypted codes

General specifications

Supply of high precision data in order to obtain a positioning error of less than one decimetre in nominal conditions of use

Supply of authentication data for geolocation information from the OS, contained in the signals

Authentication of the signals through access to encrypted codes contained in the signals

Components of the signals used

E6, E6-B component for the supply of high precision data

E1, E1-B component for authentication data from the geolocation information

E6, E6-B component for the access data for encrypted codes and E6-C component (pilot)

Specifications of the user segment

High precision positioning obtained using precise positioning algorithms integrated into the receiver and using the data transmitted in the signals

Verification of the authenticity of the data using an asymmetrical cryptography protocol transmitted in the signals and a public cryptographic key

Verification of the authenticity of the signals by decrypting the codes of the encrypted signals using a private cryptographic key

Geographical coverage

Global

Global

System architecture

High-precision 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

Authentication 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

Encryption 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

transmission of the OTAR information in the E6-B signal component

Provision of the service

High precision data provided by one or more service providers

Authentication data provided by the system established under the Galileo programme

Encrypted signals supplied by the system operating manager

Access to the service

—

Fee-paying access depending on the pricing policy in force

—

Inspected by one or more service providers

—

Fee-paying access to the encryption codes depending on the pricing policy in force

—

Access to the encryption codes monitored by one or more service providers with the assistance of the system operating manager

Deployment of the service

—

Testing and validation phase to be concluded in 2018

—

Initial commercial operating phase between 2018 and 2020

—

Full commercial operating phase from 2020

—

Testing and validation phase to be concluded in 2018

—

Initial signals supply phase between 2018 and 2020

—

Full service supply phase from 2020

—

Testing and validation phase to be concluded in 2020 at the latest

—

Commercial operating phase to begin after that.

Use of EU classified information

—

No 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.

—

No 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.

—

No 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.

Further specifications

—

High-precision data provided for the Galileo satellites and possibly for the satellites of other constellations

—

The transmission of authentication data must not lead to any deterioration in the open service

—

The authentication data must be provided for the Galileo satellites and possibly for the satellites of other constellations

—

The users of the OS accept the risks linked to the use of authentication data
