Did SN15 use Dishy McFlatface?
« on: 05/08/2021 06:59 pm »
I was wondering, was it a coincidence that SN15's stream was in 4k when its the first Starship to get a Starlink dish, or did they actually use Dishy?

Don't know if this has been asked before, couldn't find anything.

Iím purely speculating but it would explain the drop outs while also freeing up more reliable bandwidth for real-time  telemetry.

Ball is making the antennas for the Air Force, so you may very well spot one of those instead.

I kinda assumed it was using VPN tunneling through Starlink whenever it showed the UDP connection. The UDP connection itself shouldn't indicate that, it's just a matter of timing when it happened. I assumed Starlink would only work during the bellyflop, and the udp connection messages only happened during the belly flop. The only evidence is the slightly different behavior that happened after the flip along with the video working a bit better after than before.  It also failed in a different mode: normally the failure mode was a freeze, but post flip there were MPEG encoding errors. Was also wondering if they were communicating to the ground in the microwave spectrum since they seem to have a rattier signal when it is overcast.

Itís an entirely private network that was using udp multicast to send the footage.

SN11 and SN15 were both in to the clouds, without visual tracking. Maybe the video feed reception requires a directional antenna that is pointed towards the transmitter manually?

Possibly, but then again afaik you can also have an antenna just track the direction that causes the signal to become stronger, if it has any kind of spatial resolution
For a variable Isp spacecraft running at constant power and constant acceleration, the mass ratio is linear in delta-v.   Δv = ve0(MR-1). Or equivalently: Δv = vef PMF. Also, this is energy-optimal for a fixed delta-v and mass ratio.
