How to: Get faster GPS locks and Get more from Navigation

thanks a lot. greatly speeded up my gps lock. and thanks to the comment on positioning server too.

I use my 6110 for lots of navigation and getting aGPS working was really annoying me.

You can get a cheap GPS bluetooth receiver for �20.

Which do you recommend I use for the positioning server?:

• O2 MMS
• O2 Mobile Web
• O2 WAP GPRS
• O2 WAP GPRS Streaming

@bartmanekul,

I meant performance in terms of tracking, i.e. 3 meters with my Colorado verses 8 meters with my N82 while standing in the same spot. There is simply no way your 6110 can out perform a SIRFstar III equiped receiver. The military uses SIRFstar III receivers. I also have a Garmin GPSMap60CSx, and too out performs my N82. In terms of tracking, maintaining a lock, TTFF, a dedicated unit is simply better than a GPS equipted phone. Can you verify where you got the impression that your 6110 is better than a dedicated unit? With either Garmin device I can routinely get 4 to 5 satellite while indoors.

While I will admit that having my N82 is sometimes a bit more handy than having my Garmins with me, I would not trust my N82 for any serious navigation (off road or geocaching), but it is adequate for simple tasks such as traveling in the city.

Your probably right about accuracy, but in all the satnav apps Ive used (over 6), its not had any accuracy issues.

When I say outperforms, I mean get a faster lock (which it does, with AGPS). It beats my mates tomtom with a sirf 3.

Of course, Id rather have sirf 3, but you must make concessions with mobiles, and for my purposes, its always been better than a sirf 3. And probably better for most the population, unless they need to the meter accuracy, and satnav indoors.

Cheers mate,

I agree with you there. Concessions had to be made and the SIRFstar III is no sweetheart when it comes to power usage. It can be a bit hungry but that is the price you pay for sensativity. I have a Tom Tom for the car and I can agree with you here. For some reason the Tom Tom has a very long TTFF (about a min or more), but once locked on it stays locked. The idea of A-GPS would not be a bad idea for Tom Tom as many to most units have the ability to connect to a cell phone. Hey, let's propose this. We can split the royalites on the idea. 😊

Satellites whizzing around at thousands of miles an hour?... I think not!... these satellites are in geo-stationary orbit for a reason...They do not move relative to the surface.

My N82 gets a lock in less than 20sec every single time. Sometimes almost instantaneously. It's really good for me so far.

Use O2 Mobile Web

> meaning that when between buildings you need to see a quarter of the clear sky when getting a lock.

Um, not necessarily. The satellites move around constantly so are not evenly spaced. Sometimes very close together*, sometimes far apart, mostly somewhere in between. Receivers are increasingly tolerant of multi-path reception, so you can get /some/ signal off bounce, from hard surfaces like cliffs and buildings.

*Although this causes another issue, called geometric dilution of position
