I'm excited to see the Blue Bird launch

As long as you have power and a working device, you could never be lost again.

Great add!

[@goburin9962]

Great Work.🎉

This could be trillions if they can fully monetize an affordable service.

Cleared hot.

Let's take this thing to orbit

I don't really know how their satellite constellation can work with only 243 satellites. My very rough calculation is AST Space Mobile will need >1,000 satellite to be able to provide continuous coverage for ~50% of Earth surface centered on the equator, assuming the satellites orbit between 725 & 740 km, and each satellite can provide a bit over 300,000 sq-mi of coverage. This is one of the disadvantage of low earth orbit, the inclined are create a great deal of inefficiencies in coverage. The 243 satellites and orbital slots are in their petition with the FCC. I guess I'll need to hunt down retired co-workers that can do a quick calculation to see if I did something wrong. I was thinking about investing in the company, but nervous about the technical scheme.

Hi you seem like a knowledgeable person. I know it is theoretically possible, but do you think it is realistically possible with normal phone? It will be battery draining + packet loss would be insane. Anything that requires real-time data transaction would not be possible imo. I don't think it would ever be able to completely replace current mobile service without adding a receiver or building a phone specific for this use. What do you think?

[@stanimal8]

@@Silven1117 AST Space Mobile is designed to be compatible with normal cell phones (AT&T & Verizon, and maybe others). But with their initial tiny constellation of 5 LOE satellites, they'll likely only be able to provide 2-3 minutes of service once every day or two, as their LEO satellites drift quickly across the sky. Once they have their "full" 243 satellite constellation, they should be able to provide cell connectivity for 2-3 minutes maybe once or twice per hour. I guess that could be useful for texting when one is lost in the wilderness. But their competition (SpaceX's StarLink & Amazon's Kuiper) should be able to provide "continuous" satellite to cell phone coverage. So I can't figure out how AST Space Mobile's business case can work.

Well, what did your buddies tell you. ASTS can do it with 243 satellites?

[@stanimal8]

@@johnboire8610 With 243 satellites in LEO, AST Space Mobile will only be able to provide non-continuous cell coverage of maybe ~3 minutes each hour. Might be somewhat useful if you're lost in the middle of nowhere and need to send a quick text. Can't see how they could compete with Starlink (SpaceX) and Project Kuiper (Amazon) which will provide "continuous" cell coverage from large constellation (>10,000) of satellites from LEO. A potential disrupter is SES's O3b which uses far fewer satellites (~25) in MEO, although I heard they are in discussion with Starlink.

noice! 🚀

[@matt-jc9qb]

I’m so fuckin hype

[@aztucsonman77]

Really excited about how your LEO satellites can be used in self driving vehicles also.
