i'm not terribly surprised. keep in mind any built-in encryption would have to have been compatible with a device made in the mid-90s and would have had to conform to US export laws. so you're looking at, what, 48-bit DES or something like that?

Shaggar posted:are those sats still in use and could they be updated? i doubt you could add a bunch of encryption overhead to the satellite itself. wikipedia says they're running PowerPC 603e processors at around 200MHz. you'd probably have to do all the encryption on the endpoints. i don't know if the satellite handles IP traffic and voice traffic intrinsically differently.

I thought that for things like iridium the sheer range the comms has to go through prohibit any strong encryption because the S/N Ratio is already garbage and the amount of error correction it would require would be to much for general purpose satellites. All the newer government MILSTAR EHF satellites have all the encryption and error correction built in and they still struggle to get 128kbps under a spot beam.

i remember reading an article on how the US navy's satellite comms were being slammed by all the half-gigabyte powerpoint files officers loved to send around. that was several years ago, though, so dunno if they ever got around to cracking down on that or not (lol i bet not).

I'm more referring to the in theater operational spot beams. Where you have an agile one pointing at a small patch of the world where you're expected to transmit from. We managed to eke out 64kbps most of the time. The power point thing was those fuckwits in carrier strike groups, and they have multiple Mbps coverage zones wherever they sail.

in the mid-90s during the early days of Shuttle-Mir the NASA astronauts had an INMARSAT phone because it was literally easier than trying to get a working phone with long-distance service installed in Russia

Apparently the backpacks were end-of-lifed a few years ago because the phones themselves stopped being made, and there was a big scramble to get a replacement one developed. Inmarsat's just rolled out the second generation of its phone that uses the BGAN sats. As long as you're below the arctic circle it'll work, and it has better call quality/is cheaper than Iridium. Last summer I was hanging out doing ham radio stuff last summer on the top of a mountain, a retired guy rolls up on his motorbike. We started chatting about radios and stuff, then he pulls out and demos his IsatPhone that he uses in case he gets hit by a miata that missed the apex.

"uh... you've reached an elevator" lol it was 2004 and the school district had decided to go with 3com for doing VOIP phones in its newest elementary school. not sure how much of it was 3com or the IT guy who was in charge of that project but i think they literally fired that guy over it, it was that bad

I spent a month planning when we were going up to the Michigan UP to visit fam. Brought a black box (yeah blinky lights and switches in a project box in an airplane! suck it post-911-ailures) and hooked it up to their rotary, 5 digit line. A GIIIIRL called me a couple times and it never showed up on her bill. that was me specifically knowing that a dinosaur of a phone system was still in place in 1995 in Michigan tho

if you're sticking to 902-928 mhz, you can get away with a tech license as you have 1500 watts of basically any modulation if you're out of that range though, there is no license that you can buy. you'll have to fight with verizon and att in a spectrum auction.
