Hardware costs for a ground station are exceedingly expensive. Only recently has SSLEOSAT hardware dropped to the $50k level. I'm sure this is much more especially if you want multimegabit speeds both ways.

There'd still be a few seconds of latency. 22,500 miles each way + processing / routing delays.

Any non-batch / connectionless stuff would still suck. It would just suck much faster.

Depends on the orbit - the system I've used has latency comparable to DSL (100ms) due to lower orbiting satellites. If they are using this for telesurgery, for example, it will be LEO. INMARSAT, OTOH, runs about 650-1000ms and is quite noticeable.

EDIT: CNN reports 1.2 giga BYTES per second. Is that right?

My brother is in the teleradiology business, and he sent me the same link. This will be huge for remote teleradiology, with high definition images.

the latency stays the same no matter how fast and how big the dish is

the distance to/from the satellite stays the same


and i have plenty of room for a 16 ft dish, if i can get the service free

I have plenty of room, will need to buy a couple more hard drives though....when can we sign up?

Nice speeds, but I'd never use a satellite internet service if given the choice of a landline.

Yeah the latency is a problem depending on what you're doing. Good for large downloads/torrents... Bad for gaming :(

Of course it's incorrect. It should be bits per second as they're talking about transmission speed.

Japan still has to catch up with Boeing and the USAF's WGS system.

I used to get stock quotes thru a satellite service. The latency was roughly 1 second behind realtime, which as the trading of the markets got faster and faster the past 5 years, it became way too slow and I had to drop them. They eventually had major bandwidth capacity issues anyways.

Fixed mount dishes 5M do not tilt & swivel (azimuth and elevation mounts) .. that' means stationary orbit, that means ~22,500 miles where they park geostationary satellites.

LEO = Low Earth Orbit only gives ~15 minutes horizon-to-horizon at best, probably really less than ten (typical for LEO amateur radio sats was 8-12 minutes on an direct overhead pass).

INMARSAT is also geostationary.

GPS is an orbiting constellation and uses omni-directional antennas (Bi-/Tri/Quad-filar helix)

If it's a stationary dish, the satellite is parked.

Yes those reporters are always taking too large a byte and never save their bits. Makes the computer users get all stirred up in frenzy. What kind of big deal is a factor of eight anyway? :p

Our system has the actual dish inside a radome and it's gimballed because the ship moves. ;)

I put in a gimbaled VSAT system on a yacht once quite a while ago. Pretty cool system.
