Re: external gps receivers and the i-phone

2012-06-27 Thread Chris G 
You are right, they are getting the number of sats from the receiver.  They can 
also calculate the number of feet based on the hdop and vdop values.  The 
smaller the hdop and vdop the better accuracy you will have.  End users 
normally don't have access to these values.

Re: external gps receivers and the i-phone

2012-06-27 Thread Geoff Waaler 
It should also be noted that the accuracy of the iPhone 4s's receiver is very 
good.  The best I ever saw was from my iBlue 737 which maxed out at twelve 
feet.  As I recall, my iPhone 3GS sometimes got as low as 32 feet but didn't 
maintain that for very long.  I can't speak for the iPhone 4, but at some point 
the GPs receiver was apparently given a major upgrade, because my 4S more often 
than not shows 16 feet.  Now this may be an apples to oranges comparison 
because the iBlue number was reported by a Windows Mobile software product, 
where as the iPhone data was interpreted by the Ariadne GPS app, but I suspect 
that both products are simply reading this from a data block from the receiver, 
hence these numbers are meaningful.

Best regards.
