13Working Group Aeronautical Ku band (2)
Architecture Overview
14Working Group Aeronautical Ku band (3)
ETSI candidate Harmonised Standard draft EN 302
186 for Ku-band AES present status ETSI TC-SES
draft EN 302 186, requirements for Protection to
FSS systems (e.g. VSAT) Protection to Fixed
Service and Radio Astronomy systems via PFD
mask WRC-03, Agenda Item 1.11 Will decide on
secondary allocation to AMSS in 14.0-14.5
GHz WRC-03 outcome (allocation and protection
requirements) will be taken into account in the
public enquiry of draft EN 302 186 .
15Working Group Broadband Satellite Multimedia
- To produce specifications, standards and other
ETSI deliverables for broadband satellite
multimedia. This includes - Definition of satellite system architectures
supporting broadband services - Service requirements and descriptions for
broadband communications systems - Definition of network architectures and interface
protocols leading to air interface standards,
interworking standards and other user terminal
specifications. - To liaise with relevant other standardization
bodies (e.g. TIA, ITU) on satellite matters
16Working Group Broadband Satellite Multimedia (
2)
- The BSM concept is to divide theair interface
into 2 parts - Satellite independent upper layers
- Satellite dependent lower layers
- The upper layers should contain a set of common
IP interworking functions - Common ways of handling IP addressing, multicast
and QoS etc. - The lower layers contain the satellite specific
parts. - These layers are closely tied to the payload
capability of the satellite and hence cannot be
the same in all cases.
17Working Group Broadband Satellite Multimedia (
3)
- BSM WG has set the following priorities
- GSO satellites
- Fixed systems
- Internet Protocol IPv4, IPv6
- Current work items
- IP interworking standards
- Satellite Independent set of higher layer
standards - Air interfaces
- Satellite dependent families of lower layer
specifications - Satellite Independent interface (SI-SAP)
- Common interface between higher layers and lower
layers
18Working Group European Co-operation for Space
Standardisation(1)
- Satellite Ground Interface Command and Control
Link of Geostationnary Satellites - Domain Telemetry, Command and Ranging (TCR)
systems operating typically in the following
bands 5850 MHz6725 MHz uplink, 3400 MHz4200
MHz downlink, 12750 MHz14800 MHz and17300
MHZ18100 MHz uplink, 10700 MHZ12750 MHz
downlink - Sets out the minimum performance requirements
and technical characteristics of the
ground/satellite Radio Frequency (RF) interface
partially based on Spread Spectrum Multiple
Access (SSMA). - Motivation Management of the co-location
constraints for maximization of bandwidth for
Communications Missions, and interference
minimisation
19Working Group European Co-operation for Space
Standardisation(2)
- Satellite Software Data Handling Interfaces
(SSDHI) - Domain Geostationary Communications Satellite
architectures based on ISO OSI Reference Model
or SOIF Reference Model, but could also be
applied to other types of satellites. - Sets the minimum definition, services and
interfaces requirements of the satellite
communication application layer - Motivation Shorter and shorter communications
satellites development cycles and compatibility
requested with off the shelf equipments requires
interface standardisation. Independent
development of On Board Software (OBSW) of the
choice of satellite equipment by standardisation
the software specifications of the Interface
between the application software and the
communication services.

21Conclusions
- SINCE RAST 10 ETSI TC SES
- Continue the Harmonisation standard work (RTTE D)
- Continue the development of an open standard for
new broadband products - Continue to be the focal point in Europe for
Satellite Standards - And for the Future?
- Continuing the work on Open Standard under the
eEurope Broadband development - Intend to be part in the standardisation of
Galileo - Continuing the co-operation with TIA and TTA
