I would like to inform you that, with respect to the overlap issue discussed in the CESG, today SOIS and SLS Area have agreed today the following split of responsibilities:</font><font size="3"><br></font><font size="2" face="sans-serif"><br>
__________________</font><font size="3"> </font><font size="2" face="sans-serif"><br>
SLS Responsibilities include:<br>
1) point-to-point links for Planetary Communications<br>
2) multi-point links for Planetary Communications utilising CCSDS data link and physical layer protocols<br>
3) consideration of usage of Radio Frequency bands over space-ground and space-space links
</font><font size="3"><br></font><font size="2" face="sans-serif"><br>
SLS can therefore define mission scenarios/profiles for Planetary Communications, as well as functional & performance requirements and develop the pertinent Standards (Magenta or Blue Books) according to the points 1..3 listed above.</font><font size="3"><br></font><font size="2" face="sans-serif"><br>
SOIS Responsibilities include:<br>
A) networked multi-point links utilising commercial wireless network technologies for Communications onboard a space vehicle or habitat and/or surface links within the proximity of that vehicle or habitat.<br>
B) cooperation with the SLS Area for matters related to usage of Radio Frequency bands
</font><font size="3"><br></font><font size="2" face="sans-serif"><br>
SOIS can therefore define mission scenarios/profiles for Vehicle and vicinity Communications, as well as functional & performance requirements and develop the pertinent Standards (Magenta or Blue Books) according to the points A..B listed above.</font><font size="3"><br></font><font size="2" face="sans-serif"><br>
Charters and CWE Projects of the affected WGs in SLS and SOIS Areas are to be made consistent with the above set of responsibilities (if not consistent now).<br>
