PURPOSE AND SCOPE
This document contains minimum operational performance standards (MOPS) for
avionics that provide Aeronautical Mobile Satellite (R) Services (AMS(R)S) by means
of satellite communications technologies scheduled to become operational in context
of the global and regional ATM and CNS modernization (e.g. ICAO/Global Air
Navigation Plan, Europe/SESAR, US/NextGen). Each of these technologies is
individually and collectively referred to as a “Next Generation Satellite System”
(NGSS), and the NGSS nomenclature will be used throughout this document. This
document does not apply to avionics that provide AMS(R)S in accordance with the
Standards and Recommended Practices defined in ICAO Annex 10, Part I, Volume III,
Chapter 4 (Chapter 4 SARPS). Such equipment is specified in the current version of
The ICAO SARPS chapter 4 as well as the ICAO AMS(R)S manual
(document number 9925) are planned to be updated to include NGSS.
However these updates are not yet available.
Compliance with these standards is recommended as one means of assuring that
NGSS avionics will perform its intended function(s) satisfactorily under all conditions
normally encountered in routine aeronautical operations. Any regulatory application of
this document is the sole responsibility of appropriate governmental agencies.
This document contains a generic description of a satellite communication system
configuration including Ground Subnetworks; NGSS Satellite Subnetworks, of which
the Aircraft Earth Station (AES) is one part; and Aircraft Subnetworks. However, the
specified Minimum Operational Performance Standards in this document address only
the AES portion of the Satellite Subnetwork.
To comply with the minimum requirements of an application for certification or other
approval, an NGSS applicant is required to submit information regarding the technical
characteristics of the NGSS. These technology-specific technical requirements for
each such system will become normative appendices to this document. It is
anticipated that such technology-specific appendices will be created as the particular
NGSS becomes operational for AMS(R)S.
This document covers typical NGSS avionics requirements and tests for the aircraft
avionics. It includes the purpose, scope and equipment performance requirements,
recommended bench tests and other performance verification procedures, and
installed-equipment tests and operational performance characteristics. Detailed
requirements and test procedures are based on the technical characteristics
documented in the normative appendices, as discussed in the previous paragraph.
A companion document DO-343 / ED-242, Minimum Aviation System Performance
Standards (MASPS) for the Aeronautical Mobile-Satellite (R) Service (AMS(R)S) as
Used in Aeronautical Data Links, should be consulted for operational requirements at
the air/ground system level, and for details of specific systems providing AMS(R)S.
This document consists of the main body (sections 1 to 5) and the set of appendices.
The main body of the document and the appendices A and C are informative. Only the
technology specific appendices (D, E) are normative for the airborne equipment.
The main body of the document serves as a guideline for the development of the
technology specific appendices and it is structured as follows:
