You mean the time before you get a first fix, or the latency? – Wouter van Nifterick Apr 12 '13 at 12:55

The data sheets usualy state a Time to First fix of 30-40s having a good antenna. But the first time the GPS device is enabled it will need 10 - 15 minutes. Both times valuid when having free view to sky

When a GPS receiver is switched on, it needs to get the data from at least three GPS satellites before it can give its position. Generally this takes about a minute, but it might take longer if the receiver is far from where it was last used or it's been off for a very long time.
