Galileo Open Service Signal In Space Interface Control Document (OS SIS ICD), v1.2 released
(From ec.europa.eu)
The European Commission has published the latest release of the Galileo Open Service Signal In Space Interface Control Document (OS SIS ICD), v1.2, on November, 11th 2015.
The OS SIS ICD contains the publicly available information on the Galileo Signal In Space, specifying the interface between the Galileo Space Segment and the Galileo User Segment.
It is the key document allowing receiver and chipset manufacturers to be able to process the Open Service (OS) signals generated by Galileo satellites.
The document specifies Galileo signal characteristics, characteristics of Galileo spreading codes, Galileo message structure and message data contents.
The latest version is based on feedback from receiver manufacturers and other stakeholders received during an extensive public consultation in 2014.
In addition to a number of minor editorial improvements including corrections and clarifications, an annex with numerical examples of FEC coding and interleaving has been added and the licence agreement has been revised and simplified.
The document now refers to a companion document, Ionospheric Correction Algorithm for Galileo Single Frequency Users, for details on the ionospheric model used for Galileo. The E1-B, E1-C and E5 Primary Codes in Annex C are no longer included in the paper version but are available in the electronic version of the ICD.
Paper copies are available on request.
