Dear All,</font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
CMC and CESG Chair has requested to review the Area
contents (Area content tab) and goals in the CWE on-line strategic plan.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
For SLS you can find this information here: </font><a href=http://cwe.ccsds.org/fm/sp/Lists/SLSContent/AllItems.aspx><font size=2 color=blue face="Arial"><u>http://cwe.ccsds.org/fm/sp/Lists/SLSContent/AllItems.aspx</u></font></a><font size=2 face="Arial">
and at the bottom of this mil for your convenience.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
Keeping in mind that we have six goals (i.e. one per WG), can you please
review the general description of SLS Area and (at least) the goal related
to your WG?</font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
<br>
I think the contents below are quite stable and I would expect only minor
changes (if any).</font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><b><br>

I would appreciate receiving any comment by 10 July 2015.</b></font><font size=3 face="Times New Roman">

==================================</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><b><br>
SPACE LINK SERVICES AREA</b></font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
The objective of the SLS area is to address all of the point-to-point
communications links and protocols that interconnect a spacecraft with
its ground-support system, or with another spacecraft, by developing standards
for efficient and reliable space link communications systems addressing
nominal as well as emergency scenarios. Specific attention is given by
SLS to needs for higher data rates and better link performances, a standard
security mechanism, and lower cost, mass, and power.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
<br>
SLS area objectives focus on Layers 1 & 2 (of the Open Systems Interconnection
[OSI] protocol stack)—i.e., the Physical Layer and the Data Link Layer.
This means that SLS concentrates in particular on radio-frequency and optical
systems, modulation, synchronization and channel coding, and data link
protocols, for both long-haul (e.g., spacecraft-to-ground) and proximity
links (e.g., orbiter-to-lander). Moreover SLS concentrates also on two
additional functions essential on the space link: data compression for
end-to-end data transfer optimization, and ranging for accurate orbit determination.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
<br>
The SLS area needs to coordinate:</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
with CSS for the identification of relevant parameters for service
management;</font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
with CSS for the inner behavior (i.e., the implementation aspects
and not the terrestrial interface characteristics) of the CSTS to be made
available to other agencies;</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
with SEA for Delta-DOR issues;</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
with MOIMS and CSS if the need of standardized exchange of meteorological
and orbital data will be required for optical communications;</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
with SEA for adoption and integration of security-related recommended
standards and practices;</font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
the SANA-recommended practices for registries and repositories.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
<br>
The strategic goals of the SLS area are presented below.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><b><br>
<br>
SLS GOAL 1</b></font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
Enable efficient bi-directional transmission for
near-Earth spacecraft (including missions to—and/or orbiting around—the
Moon and at Lagrange points) and deep-space spacecraft (especially Mars
missions) by developing appropriate modulation schemes for telecommand,
telemetry, and ranging signals in the applicable frequency bands while
providing narrower bandwidth and higher data returns.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><b><br>
<br>
SLS GOAL 2</b></font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
Produce efficient standards for coding schemes
and synchronization, providing new generations of space missions with telecommand
and telemetry capabilities beyond current technologies, such that spacecraft
interconnection with its ground support system, or with another spacecraft,
can accommodate higher data rates and better link performances, together
with lower cost, mass, and power.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><b><br>
<br>
SLS GOAL 3</b></font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
To provide efficient space data link protocols
capable of satisfying the needs of current and future missions; i.e., to
produce or maintain standards to support smoothly higher data rates with
seamless interface to both user applications and communication technologies
over radio frequency (RF) and/or optical links.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
<b><br>
SLS GOAL 4</b></font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
Develop data compression standards enabling efficient
data rates and volume reduction to maximize the usage of available space
links bandwidth and onboard storage capacity. These internationally agreed
data compression standards will foster interoperability and multi-mission
development of compression functions.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
<b><br>
SLS GOAL 5</b></font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
Provide security functions operating at Layers
1 & 2 (of the OSI protocol stack) of CCSDS space links. The targeted
security services include authentication, integrity check, anti-replay,
and confidentiality both for uplink and downlink. The corresponding security
protocols/functions shall be compatible with CCSDS TM, TC, and AOS data
link protocols and be independent from any specific cryptographic algorithm.
Develop associated management functions for monitoring and control, key
and security association management. Security at Physical Layer level should
also be considered.</font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
<b><br>
SLS GOAL 6</b></font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
Establish a common framework of standardized services
for space optical communications for interoperability and cross support
by creating new standards for optical links (ISO Layers 1 & 2), taking
into account the uniqueness of these types of links, such as very high
data rates, geographic station diversity, and atmosphere (“weather”)
influences. Consider also the services to be offered/required to/by space
data link protocols and relevant procedures. Finally, identify the needed
coordination with other CCSDS areas.</font><font size=3 face="Times New Roman">
