How does JetBlue show D*

[Strong]

Hey there. I was wondering how JetBlue's D* system works? Is there any technical information floating around about it?

TIA,
Strong

I've read that the service is actually something like a 24 channel hotel setup (i.e. there's not a receiver in every seat, just 24 receivers each tuned into one channel with modulated output)
The dish is likely in a bubble controlled by a gyro and GPS for continious, accurate positioning, (like RV system) as I do not think a phased array antenna was commercially available until last year (bunch of signal mirrors on a flat surface), and jetblue I think has been around longer.

there are not 24 receivers! There are 2 receivers. The two Multi-channel Receiver Modulators (MRM) act as tuners, among other things, and each handles twelve channels of the service. read more here. http://www.airfax.com/airfax/features/viewstory.asp?filepath=feb2004%5Clivetv.htm

Haven't you ever heard of Verizon AirFone? :D
(formerly GTE AirFone)

Only $4 to connect :eek2: and $4 a minute :eek2: , unless you're a Verizon Wireless customer ($0.69/minute).
