LIVE: SpaceX Dragon COTS Demo (C2+) FD2 and FD3 UPDATES

[Jorge]

maybe some one from MCC could explain this:

UHF SPace to Space Station
          Radio 1 Power OFF
          Radio 2 Power Off

UHF Sync Lock : frame Synch unlocked

IAC1 Power Active
IAC2 Power Backup

It has been a long while since I've worked with these, but here is my interpretation.

The Space-to-Space Station Radio (SSSR) is the ISS end of the UHF radio link to the Space-to-Space Orbiter Radio (SSOR) and is also used by the EMU.

The SpaceX CUCU, used to communicate with Dragon, shares the same UHF antennas on ISS. After CUCU was installed, we found that it interfered with the SSOR-SSSR link.

So I'm guessing they need to turn off the SSSR to prevent interference with CUCU during Dragon ops.

Thanks Jorge, helps to get insight into the data we are seeing.

About 110 miles away and the spacecraft is now in direct communication with the Space Station

Why are people tied to their desks?

Because the 'wireless era' has not reached everyone... yet...

Mr. Byerly just covered this, but to recap:

[Ronsmytheiii]

Entering orbital night, if the camera was pointed the other way we would be able to see Dragon after everything else was black for a bit
