New Galileo Open Service Signal-In-Space Operational Status Definition Document Now Available
The European Commission has just published the first version of the Galileo Open Service Signal-In-Space Operational Status Definition (OS SIS OSD) Document. The processing of Galileo Open Service signals and the use of Galileo Open Service relies on the publication of four Galileo documents. The first two documents are already published and consist of the Galileo OS Signal-In-Space Interface Control Document [OS SIS ICD, Issue 1.1] and the Galileo Ionospheric Correction Algorithm for Galileo Single Frequency Users [Ionospheric Correction Algorithm for Galileo Single Frequency Users, Issue 1.1, June 2015]. The third document is the Galileo OS Signal-In-Space Operational Status Definition. A public consultation for this document will be launched next week. The fourth document, to be published in the coming months, will be the Galileo OS Service Definition Document (OS SDD).
The OS SIS OSD document is available for download here.
Document Overview
The document is divided into three main sections:
- A comprehensive guide explaining how the status of the Galileo SIS is disseminated by the signal itself through specific data within the Navigation Message.
- Important considerations about the use of navigation parameters, recalling the reference for the ionospheric model used by Galileo.
- Additional considerations on the validity of navigation parameters.
Additional Information
The European Commission and the GSA are holding an open public consultation for the first version of the Galileo Open Service Signal-In-Space Operational Status Definition (OS SIS OSD) Document The public consultation will be accessible next week.
