For certain things I use a handheld GPS. It is a great tool. You turn it on, have a clear section of sky, and in maybe a minute, but sometimes much longer, sometimes a little shorter, you have a lock on enough satilites to get your position. If you put your GPS in your pocket you could easily loose the lock. Also I have one that is known to have one of the best receptions, locking faster and holding a lock better then most other handhelds. The antenna is about 2 inches by about 3/4 on an inch (triangular prism), external and somethng called a quadrectifier antenna.
My cellphone has that new e911 GPS feature, I have the option of using it all the time or only for 911 calls. For something that I usually have in my pocket, how could this little cellphone, with what I assume is a small patch GPS antenna, possible get a lock fast enough. It seems like (from handheld GPS experence) it would take 5 minutes in an open field to get a position (from the size of it). How could this feature possible work fast enough to be useful?
Some other quetions:
How come I can’t use the phone as a GPS, if it as a GPS built in, I would think it could easily give me my coordinates?
Does anypart of the GPS function if I have the phone set to (use GPS) 911 only?
How much additional power does the ‘GPS for every call’ feature use?
