The European Union Agency for the Space Programme (EUSPA) has launched a call for expression of interest to invite external stakeholders to participate in a testing campaign of the Galileo High Accuracy Service (HAS) Signal in Space (SiS) broadcasting. The deadline for submissions is 11 June 2021.
The call targets in particular the participation of receiver manufacturers developing Galileo E6-B/C receivers that will implement Precise Point Positioning (PPP) corrections based on the Galileo HAS in their devices. The campaign is an essential step towards the development of the HAS operational service phase.
Goal of the campaign
By providing access to the HAS SiS Interface Control Document (ICD) to interested parties, through this call EUSPA aims to enable the participation of relevant stakeholders to the incoming HAS SiS testing. Through this participation EUSPA will collect relevant feedback on the HAS SiS ICD structure and implementation at Receiver level. It is also interested in the participants’ results received during the HAS SiS testing and any relevant implementation aspects, and on receiving their inputs and suggestions concerning the HAS service-related aspects and specifications.
Access to the HAS SiS ICD will only be granted subject to the signature of a Non-Disclosure Undertaking by the interested parties complying with the conditions indicated in the call. The HAS SiS ICD will be published during 2021, after the conclusion of this testing campaign.
The tests carried out by the participants may cover tracking and processing of GPS and Galileo signals relevant for HAS, as well as decoding and processing of the HAS broadcast corrections, in addition to user positioning performance evaluation.

Galileo High Accuracy Service
The Galileo HAS will be an open access and free of charge service based on the provision of precise corrections (orbit, clock, biases, atmospheric) transmitted in the Galileo E6 signal (E6-B, data component) from a subset of the Galileo satellites, allowing the user to achieve improved positioning performance.
The precise corrections provided by the Galileo High Accuracy Service will allow users of the service to reduce the error associated with the orbit and clocks provided through the Galileo Open Service broadcast navigation messages and the GPS Standard Positioning Service navigation data. These corrections, together with the biases provided by the service, will enable users to perform decimetre-level precise positioning accuracy. Future evolutions of the service will include regional atmospheric corrections to improve convergence times.
