Purpose of This Document

This document sets forth the characteristics of the integrated Global Positioning System (GPS)/Global Orbiting Navigation Satellite System (GLONASS) sensor unit (GNSSU) portion of a GNSS system intended for installation in commercial aircraft. The intent of this document is to provide general and specific design guidance for the development of GNSS sensors for airline use. It describes the desired operational capability of the GNSS system and the standards necessary to ensure interchangeability

This Characteristic defines two stand alone device configurations that may also be referenced by other Characteristics which may provide a GNSS function integrated within another device. For example, ARINC Characteristics 755, 756, and 760.
