The call was held, as customary for $ASTS, announced on short notice and on the latest day possible for a non-accelerated filer.
Pre-admitted Q/A and on-call analysts are getting a bit better for each new call and were interesting, but before that they had the presentation.
3/
Only thing out of pattern, was that call was held pre-market.
Might be what they like to do on a Friday for the analysts etc.
Abel Avellan initially adressed the status of current testing with test satellite BlueWalker3:
4/
Lets stick to that subject.
Prior to tests I had discussions with @steve_larrison, RIP brother, on the nature of these tests.
”Testing is a process not an event”, he said. And I agreed.
”Investors will expect quick results, it will not be like that, it will be gradual.”
5/
His expertise was the software part, whereas mine is the mechanics. And where we differed was on risks.
I downplayed mechanical risks of bw3 versus the software/electronics risks.
In that we saw the bigger risks in what the other knew best. Which is natural, I guess.
6/
To this date, and as far as we know, mechanical / deployment worked as intended.
Software/electronics/RF seems on track. In a process / on track.
And for where this track leads lets hear Steve on what he knew best.
Software.
7/
Steve emphasised sa is software defined. And that means ASTS have the tools to tweak the sat software until it works.
It will take time, but if the mechanical deployment works (which it did), Steve was very confident they would make it all work.
Abel: ”Never satisfied”
8/
Ofcourse he had a point there.
Whereas the mechanics are dead-simple IF they fail there is nothing to do.
Whereas the electronics & software are complex stuff you can tune and tweak them until you are satisfied.
Abel: ”We are there in the downlink”
9/
In summary the company states they have achieved Broadband speeds (Abel: 30 mbit) in the downlink, and validated the tech end-2-end.
Scott on Mechanical and end-2-end: ”in our back pocket”
10/
Let me be clear that what they achieved so far is monumental, not just for $ASTS.
Uplink is something I never expected broadband speeds in, the link is a bit harder to make.
Which is the reason why carrier aggregation will be key to use also midband in downlink.
11/
But so far they use lowband, which allows the strongest connection.
There is an anlogy to towers. They also started w lowband and then evolved. Sats will follow.
Public Safety net is also lowband.
12/
And so it is apparent that $ASTS has results of significance, yet they are not ready yet to present them.
At the heart of this is the nature of tweaking a software defined network becoming gradually better.
When is is good enough?
Scott is apparently thinking of HOW
13/
He is no longer thinking about IF they will announce succesful tests.
I have a canary-bird test for that statement:
Orbital data.
The instrument at hand besides software tweaks that $ASTS have to improve link budget is altitude.
It is unchanged at ~500km.
Test✅
14/
If they had problems to make the link they would have lovered their satellite (like SpaceX v2 mini). They did not.
As to complete that analogy having only one test sat, $ASTS test window is narrow that test & tweaking _process_ is supposed to take some time.
15/
As for orbital data. Radar Cross Section has been ”Large” all of this year. Well after deployment.
And for exactly 1 month oct 6 to nov 6th. Well before deployment during some of the time inside the LVA.
The latter period of in conjunction with a higher mean drag level.
16/
And so there are some patterns there that have not been explained.
Seems also that some things was done to alter the reflections from the spacecraft (/-s) to mitigate solar flares / brightness.
17/
A first for an $ASTS call was to acknowledge the defense and intelligence use case of NTN sliced 5g.
I like to add to that the fact of FPGAs BB block1 & BW3s ability to do other coms than transparent architecture cellular. And the odd orbital signatures may be related.
18/
I did this on a previous call. For some reasons they shifted to 5 block1s (FoGAs) on a single launch.
Supposed (then) to go up near years end.
19/
On this call they clarify/ bump that launch of 5 Block1s into Q1 2024.
Abel also say it will be on single F9 which means inclined launch.
(Southern USA at least covered maybe all.)
20/n
There seems to be final negotiations ongoing. But where this leans is hinted with the words ”near continous” for 20 Block 2s.
On equatorial it is continous and so this hints to Block2s slso going inclined (perhaps an AT&T or gov/DoD deal could see them cover USA?)
/21
Launch cost increases and material cost increases propagates to satellite cost increases which now are projected to cost:
20-22 Mn per block 1,
16-18 Mn per block2.
I plan to continue this thread on regulatory versus tech timeline.
Now for some coffee ☕️
/22
Let us work from this old image to understand timelines.
We see how BW3 launch was bumped to its sept 10th launch and the planned 2 seperate bluebirds (for equatorial) became 5 FPGAs on single F9.
That we now know will be inclined. (F9 does not have power for equatorial).
/23
And so USA and India are in the play for 2024-2025 tech timeline.
And so the tech timeline looks a bit like this and seems to be targeting inclined orbits. Abother hint to that is the statement at the call FPGAs (block1) will form joint constellation with ASICs (block2s).
In short they aim for US market.
There is also regulatory timeline.
/25
I expect the Block1 production line at Midlabd (FPGAs) to continue in parallell with ASICs at Odessa plant beyond BBs 1–5.
That these are produced in parallell.
ASICs are high capacity 10x vs FPGA
But FPGAs are flexible 100x vs ASICs
/26
One reason I think so is my knowledge of military affairs.
Listen to Lance Spencer(AT&T defense) for instance.
It is not just me.
/27
Back to that timeline.
In 2020-04-13 $ASTS applies to the FCC to be granted US market access for their SpaceMobile constellation.
Starting a regulatory pathway.
28/
That docket is here and in functional freeze, simply waiting for something .
The objective of BlueWalker3 is to test many things. It is a novel form-factor satellite. Q/V backhaul dishes and cellular fronthaul phased array all new.
But if the RF loop is closed on 4g/5g protocols I would call that a success.
If broadband speeds are achieved, even better.
The $ASTS BlueWalker3 5g coverage lowband servicelink in band5 of 892MHz is being picked up in central Europe and North America, along with FirstNet servicelink frequencies. These are downlink frequencies, sat to handset used at / near Midland, Tx.
The mode QPSK stated by the hobby astronomers for FirstNet DL is used for Physical Broadcast Channel, PBCH, in the DL, and is broadcast from the eNB (basest.) to all UEs(users)
After initial cell synchronization completed, UE reads MIB (Master information block) on PBCH.
2/n
The mode stated on band5, is so far just ”FM”.
However it is interesting that these signals are also being picked up in Czechia and Slovenia of central Europe. Testing is to be on 6 continents, but the European state(-s) was not disclosed on recent update.
The proponent of this particular Bear narrative, James Dunstan, did so under the name of ”Tech Freedom”. He is also a registered agent of competitor Lynk, which he failed to mention in that article.
”unless .. AST & Science seeks a license from a country willing to abide by international space norms, the FCC should not grant the market access request.”
