So Starlink sats are being deployed.... not just a few to test but now 300! and 120/month planned. Also the military are successfully communicating through these sats, not only in a simple test, but now in practice battlefield trials.Also SX are talking as if they can roll out some connectivity to N USA and S Canada, late this year.Therefore they must have cracked this nut. The military seems most convincing to me, for phased array success. For a fast jet travelling some 600mph, (possibly turning ?) to connect to satellite (s???) moving above at some 17,500mph and the system to work, means the signal direction is changing! QED.OK the current system could be very expensive! But with 120 SATS a month heading for orbit, it would be a surprise if they plan to ditch this lot due to incomplete phased array work!It remains possible, that the consumer receiver version is still (too) high cost, but even so I suggest the argument above indicates they have mastered the main tec hurdles.If further improvements are needed for performance and cost - which I assume is likely, these will not stop customer roll-outs this autumn/winter!It is another significant technological step for the world, that SpaceX has taken.(Separately inter satellite links appear to have been shelved, as SX is talking about local ground stations. If the laser link hardware is not on these sats, that will have to wait for a future version.)

From listening to Viasat's earnings conference call (I read the transcript), Viasat's CEO is acting like the only difference between Viasat and Starlink is latency. Viasat and EchoStar (HughesNet) are trying to imply to Wall Street that GEO = lots more capacity while LEO = lower latency. In reality, Starlink will have lower latency and something like 60x more capacity also, even at only 12,000 satellites.I am not joking when I say 60x more capacity. SpaceX at 12,000 satellites x 20 Gbps = 240 Tbps42,000 satellites X 20 Gbps = 840 Tbps. Viasat's 3 new satellites in GEO (plus older satellites) will bring them to 3.5 Tbps. At 42,000 satellites, capacity advantage Starlink by a factor of 240x in capacity. 840 Tbps to 3.5 Tbps.Frankly, I don't see how Viasat and Echostar survive. SpaceX will be able to offer ridiculously better monthly plans in terms of speed, latency, data caps (or no cap at all) and price. HughesNet is even worse than Viasat. Their new (doesn't launch for years) Jupiter 3 satellite is only 500 Gbps in GEO.

(Probably true for OW too.)
One thing to remember though when comparing GEO vs LEO constellations is that the GEO sats will probably be able to achieve higher capacity factors, perhaps ~2x. This perhaps makes OneWeb worse than Viasat, and making them need New Glenn to achieve competitiveness.Another thing, is that I would be very surprised if Starlink sats did not grow in capability by the time the ~30k constellation is deployed. I am of the opinion that once they hit the 30k number they will grow the size and capability of their satellites.

Overall he agreed with your numbers, but said that utilization percentage while in orbit brings Viasat back to being cost competitive with Starlink.He is estimating that LEO utilization will be between 10% to 20% of nameplate capacity in orbit, which also affects cost per Tbps. SpaceX may launch 80 Tbps by the end of 2022, but only 8 to 16 Tbps will actually be usable capacity based on where the customers are. That all makes sense and is perfectly understandable.
Practically speaking, there aren't many users that need multiple terabits per second in a single location. But a single airliner or cruise ship with hundreds of passengers could easily run into the tens of gigabits the middle of nowhere. So could a small island nation, and there are 300+ islands worldwide with populations over 100k people each, and many, many more with 1k to 10k people.With good penetration into only a dozen or so widely separated markets of a few thousand or tens of thousands of users each, Starlink could easily hit 25% utilization or more. With the marine and airliner markets, and widely spread DoD applications, they might crack 40%.
The Viasat CEO's point was that there are massive areas of land that will likely be totally off limits to Starlink. Russia, China, etc. Huge population, totally useless capacity while Starlink is over that area. I sort of disagreed with him on that point. The telecom companies of China can buy Starlink capacity, put the Starlink antenna on their roof, then do their censorship on their side in the data centers. Viasat CEO pointed out that telecom backhaul prices are extremely cheap and the lowest margin part of the business. Telecoms buying capacity from each other, they don't pay much and won't pay SpaceX much for it either. So yes, the capacity may be consumed, but Starlink won't make much money off it in those scenarios.The money, the high margin revenue, is in selling direct to your customer and owning the customer relationship.
Even based on what he said, it seems like he is frustrated that the SpaceX strategy is just to run circles around the FCC and launch launch launch before anyone can tell SpaceX to slow down and be safe in orbit.
The CEO of Viasat also belives there is no chance that SpaceX launches 42,000 satellites. He thinks they will have problems proving that it is safe enough to launch more than 3,000 to 4,000 without the collusion risk rising above 1 in 1,000 which is what the FCC is requiring. That seemed a bit of wishful thinking to me. Even based on what he said, it seems like he is frustrated that the SpaceX strategy is just to run circles around the FCC and launch launch launch before anyone can tell SpaceX to slow down and be safe in orbit.

Nobody is running circles around the FCC; SpaceX is still early into filling out their initial shell and have systems for automated collision avoidance, as they have correctly determined that you can't have humans in the loop for every event with such large numbers of satellites.It may relate to the scalability aspect - it seems much easier for an LEO system to expand its capacity to meet demand then it would be for GEO system. So a GEO system would aim for very high utilization of "nameplate" capacity, and once they've reached that capacity then they're done capped out for that generation. The LEO systems by contrast need to be able to survive on a much smaller percentage of nameplate capacity, but have an easier time scaling out to meet increased demand. That may be one reason Viasat would criticize the prospect of such large numbers of satellites being permitted.

After talking with Mark Dankberg, my thoughts are ... if SpaceX has a clear cost advantage over OneWeb (which appears to be very accurate), then what is the business case for funding a 3rd or 4th constellation which will have inferior spectrum rights and higher cost per Tbps? Can any business case be made for Amazon Kuiper when they are so far behind already? The only thing OneWeb has going for them is superior spectrum rights (outside of the USA) and OneWeb is roughly tied with SpaceX for first mover advantage.
Another point Mark made. Viasat has purchased 3 launches. One on Falcon Heavy, one on ULA Vulcan and one on Ariane 6. He said those three were all cost competitive with each other. Minor differences. Falcon Heavy's only advantage is that it can get the Viasat 3 satellite closer to it's final orbit so there is less time spent raising orbit. However, when Viasat put down a deposit on Falcon Heavy, he said SpaceX promised him that they are not planning to compete in Viasat's markets with Starlink. (he laughed when he said that) He indicated that he won't be buying any more Falcon Heavy launches after this final one that they have already paid a deposit on. Going forward only ULA Vulcan or Ariane 6 for Viasat launches.
Viasat doesn't have to waste their capacity aiming at the the Southern Ocean or large parts of the Pacific Ocean. There is nothing there. They can specifically cover the Hawaii area and common air routes between N. America and Europe or N. America and Asia. The Viasat CEO's point was that there are massive areas of land that will likely be totally off limits to Starlink. Russia, China, etc. Huge population, totally useless capacity while Starlink is over that area. I sort of disagreed with him on that point. The telecom companies of China can buy Starlink capacity
