ED Decision 2013/031/R

A Global Navigation Satellite System (GNSS) sensor provides an acceptable source of synchronised UTC time.

Time synchronisation is required by ICAO Annex II, chapter 3, section 3.5 as referred by EUROCAE Document ED-110B, section 3.3.2. It is also identified as a safety requirement in EUROCAE Document ED-120 (e.g. SR-ACL-15).
