thnx a lot! the POSITIONS too... yes of course...
and then from the old positions, it ( either the software or GPS chip itself?) tries to predict the new positions, somehow, I suppose?
based on time difference? (because it cannot account for your movement)..
Also I wonder if some info from the internet / third parties is used here (like that AssistedGPS etc?)
And then, the problem is
- why some ROM`s / some carriers' phones are able to
update the sat positions correctly, and also use new sats if available,
while SOME others (like Bell phones) are stuck with old useless sats/positions,
and never search for the new ones before soft-reset..
hmmmm.. I've also seen around here written
that there's a dedicated GPS area in memory, somewhere in the "radio" section?
but the "radio" must be ROM, is not it?
and this are must bes flashed often while GPS works... or only when it stops working?
or GPS chip has some RAM/ROM itself?
