Report of activities of EUROCAE WG-82 on SATCOM
(Presented by Egon Koopman, DFS Deutsche Flugsicherung GmbH)
(Prepared by Armin Schlereth, DFS Deutsche Flugsicherung GmbH)
SUMMARY
This working paper provides the report on new activities of EUROCAE WG82 related to standardisation of SATCOM. It gives an overview of actual
activities and future planning.
ACTION
The meeting is invited to take note of the information outlined in this report.
1.
Introduction
EUROCAE WG-82 has been established to develop the appropriate standards relative to new air-ground
data link technologies including data links for airport surface and En Route /TMA using terrestrial and
satellite communications. Current work on AeroMACS, which is a WIMAX (IEEE 802.16 - 2009) based
system for airport surface communications, is planned to be finalised Q1/2015. Profile and MOPS for
AeroMACS have been developed together with RTCA SC-223.
As a second future air-ground data link technology SATCOM has become mature enough to start work on
standardisation within EUROCAE WG-82 as well. This report provides an overview of the activities and
future planning related to SATCOM. Regarding the new initiative for SATCOM collaboration with
RTCA has been started. The goal is to publish MASPS (Minimum Aviation System Performance
ACP-WGS01/WP-xx
-2-
Standards) and MOPS (Minimum Operational Performance Standards) for SATCOM Class A and Class
B together with RTCA SC-222.
Further on coordination with other relevant working groups of EUROCAE (e.g. WG-78) and Special
Committees of RTCA (e.g. SC214 and SC206) are envisaged.

TOR of WG-82
The following text is an extract of the TOR of EUROCAE WG-82 and provides an overview of the
standards to be developed and the time planning for delivery of these documents:
Working Group Objectives:
Satcom datalink
Standardization of Class A and Class B SATCOM performance levels.
It has already been identified in ICAO ACP that the current SATCOM (AMS(R)S) include relaxed delay
requirements (20 and 30 seconds) which are not compatible with the performance requirements of the
services required to support the SESAR and NextGEN concepts. Therefore it is needed to update the
current SATCOM SARPs to include more stringent performance requirements.
For this purpose, EUROCONTROL has established the NEXUS group to facilitate the development of a
consensus proposal to ICAO for an update of the current AMS(R)S SARPS, while maintaining the
compliance of the existing SATCOM systems.
Therefore, NEXUS has agreed to structure the proposal to ICAO identifying 3 classes of performance
requirements (Class A, B and C) for SATCOM systems as follows:
1) Class C will cover the performance requirements included in the current SARPs and will be applicable
to systems already standardized in ICAO (such as INMARSAT Classic Aero/I3, MTSAT and Iridium).
Class C is effectively covering oceanic operations.
2) Class B will cover more stringent (compared to Class C) performance requirements (such as the ones
required by i4D) and will be applicable to existing but not currently standardised in ICAO SATCOM
systems (such as INMARSAT SBB/I4 and Iridium Next) and which are expected to be considered for
standardisation in ICAO. Class B will cover oceanic and continental operations.
3) Class A will cover more stringent (compared to Class B) performance requirements (such as the one
required by full 4D and the SESAR and NextGEN future concepts) and will be applicable to future
SATCOM systems (not available today). Class A will cover oceanic and continental operations.
The Class A performance requirements are important as they will serve as design drivers and guidelines
for the development of the future SATCOM systems. In addition, it is desired to develop a global (ICAO)
standard for a SATCOM system supporting the Class A requirements and allowing different service
providers using the same set of avionics to avoid interoperability/interference issues and stimulate
equipage.
For Class A air ground data link standard will be derived from the Technical Specification issued by the
ESA Iris Programme and developed in the Iris ANTARES project.
Intended performance requirements can be found in:
Mission Requirements Document from SESAR P15.2.6
Definition of QoS capabilities from SESAR P15.2.4
ICAO Communication operating Concept Requirements (COCR)
-3-
ACP-WGS01/WP-xx
For Class B air ground data link standard development will extend RTCA SC-222 material considering the
EUROCAE ED-228 and ED-229 to cover continental airspace performance requirements with support
from SESAR P15.2.5 and ESA IRIS Precursor (INMARSAT SBB evolution).
The following RTCA SC-222 material is available and will be updated accordingly:
RTCA DO-262B: SATCOM MOPS (Class C)
RTCA DO-343: SATCOM MASPS (Class C)
The working group should provide a set of documents; some of them being used to provide basic inputs
for ICAO SARPS development and the others to be used as recognised means of compliance. The
following documents should be provided:
SatCom Class B expected delivery by 2016
ED-XXX System level MASPS
ED-YYY Airborne equipment MOPS
Documents will be further developed to cover also SATCOM Class A.
SatCom Class A expected delivery by 2017
ED-XXX version A System level MASPS
ED-YYY version A Airborne equipment MOPS

Status of Work
Currently the way how to develop the MASPS and MOPS documents is being defined. The idea would be
to use already published RTCA documentation (DO-343, DO262B) for Class C and expand it
accordingly. Further coordination with RTCA in that context is required. Inmarsat volunteered to lead
development of MASPS and Honeywell volunteered to lead the development of MOPS for SATCOM
Class B and Class A.
