Sure. Beam angle becomes a major factor when you're really close though
<kc8apf>
Hence why there are various relay systems in MEO and GEO.
<sorear>
yes
<sorear>
can you actually use any of those relay systems from a cubesat? financially
<kc8apf>
I'd have to ask a former colleague who has used them in the past
<kc8apf>
One thing starlink could provide is a GPS alternative
<sorear>
does anyone think starlink is actually going to meet the FCC deadline for launching all 12,000 satellites
<kc8apf>
Maybe. When we were designing Google's constellation, SpaceX had a path to having enough launch vehicles
<kc8apf>
IDK how densely they can pack them in a dispenser for falcon
<kc8apf>
Actually operating 12000 is a very different problem and I expect SpaceX to fail at that
<kc8apf>
Conjunction planning becomes impractical to deal with individually
<Ultrasauce>
how would starlink provide gnss without a significant increase in cost, complexity, mass etc for the satellites?
<kc8apf>
They already need to know where each satellite is with high precision just to make the data links work
<sorear>
do the satellites transmit time codes on multiple frequencies?
<kc8apf>
It wouldn't provide quite the same positional accuracy due to less precise clocks
<kc8apf>
But initial fix would be fast
<kc8apf>
sorear: depends on exactly how they decided to implement the user links
<kc8apf>
In that kind of constellation, satellites move overhead quickly so downlinks to a user need to be handed off continuously

You can solve that a few ways. Some are closer to a gnss than others
<kc8apf>
Initially, the team that broke off from Google and went to SpaceX were concerned about data routing complexity. The team that understood that part stayed at Google.
<kc8apf>
So they were looking at bent pipe models
<kc8apf>
I've lost track of what they actually implemented

how do you pronounce "migen"
<Lofty>
lain: rhymes with pigeon
<Lofty>
MIlkymist GENerator
<whitequark>
nmigen though you pronounce in any way that gets the name across
<whitequark>
it's like qemu. not even people who work on nmigen can agree how it's pronounced
<lain>
lol
<lain>
well I defined one of my fpga boards as an nmigen platform, and I made some leds blink. progress.
<Lofty>
I'll be honest, I lean towards a long I in "nmigen" (en-mai-gen)
<qu1j0t3>
smidgen
<Lofty>
"A smidgen of nmigen" would be a good name for a talk
<lain>
ehehe

i definitely said 'mai-gen' for the old one so 'en-mai-gen' seemed obvious now
<awygle>
en-mee-gen
<awygle>
although n-midgeon might have been what i said if i saw nmigen before migen. migen looks japanese so i pronounce it that way.
