Is the ephemeris data transmitted by all satellites 'in phase' or is it
"store and forward" with staggered phases?

Seems that if one can find one satellite in 'search' mode, one could find
more than one, and so download different pieces of the almanac and ephemera in parallel
to shorten the cold start time.

And with software correlaters, having more horsepower would mean more correlaters
so more satellites found sooner (only if the data transmissions are NOT synchronized
so parallel loading of the data was feasible).

And if this ISN'T the case, wouldn't changing the system to staggered data
transmission allow for this to happen? Patent anyone?

Expert comment anyone?
