PR 1.3 has improved GPS lock speed
Has anyone else noticed the significant improvement in GPS performance since updating to PR 1.3?
I'm seeing a real improvement, even when turning it on in a different location from the last usage. |

Maybe just placebo effect, but appears that way to me. |
Re: PR 1.3 has improved GPS lock speed
It's very true.. and I'm using supl.nokia.com which used to be dead slow.. now gps lock just a few seconds.... yay to PR1.3 :D
|
Re: PR 1.3 has improved GPS lock speed
I have the same placebo effect concerning better positioning
|
Re: PR 1.3 has improved GPS lock speed
Seems to be more accurate.

Re: PR 1.3 has improved GPS lock speed
Yes, I agree. It used to be VERY slow, but now fairly useable.
|
Re: PR 1.3 has improved GPS lock speed
DIS LITTLE GPS POINT HUGE changes
|
Re: PR 1.3 has improved GPS lock speed
I haven't noticed that (but I DID think I had noticed that with PR1.2!).
|
Re: PR 1.3 has improved GPS lock speed
Seems to be faster here too...had been using supl.google.com prior to this, didn't realize the update changed it back to nokia, that's a testament to it being much faster.
|
Re: PR 1.3 has improved GPS lock speed
+1 for that.
seems to be really faster and the sites load much better |
Re: PR 1.3 has improved GPS lock speed
Interesting. Is this using SUPL? I wonder if they've upgraded the GPS chipset firmware or if it's a change to the ARM-side processing of the SUPL data?
|
Re: PR 1.3 has improved GPS lock speed
i found that interesting too,cause our "maps" look a little bit less epic fail.
anyway like that. |
Re: PR 1.3 has improved GPS lock speed
Hmm, will test it.
|
Re: PR 1.3 has improved GPS lock speed
Yeah, when I updated Maps I thought the same thing. Lock is much better now. Kudos to 1.3. No real new features but fixed A LOT of little ones that make this device so much better to use.

Of course still a far cry from a real navigation system, but we'll just have to wait for Meego for that, hopefully. |
Re: PR 1.3 has improved GPS lock speed
I don't see any differences at all. Seems to be the same :)
Placebo effects!! |

Seriously though, you don't notice an improvement? I achieve lock in a steel building now. |

I think people think that GPS locks faster because they never experiencing the locking speed before, nor paying attention to the timing. Placebo effects! |
Re: PR 1.3 has improved GPS lock speed
I suggeset flash it back to PR1.2 and then timing it. Then flash it to PR1.3 then timing it as well. Comparing both time and if you got a proof then I'll believe ya :D
|
Re: PR 1.3 has improved GPS lock speed
Yes I noticed that too. It locks really fast now. Maybe it' s supl server that makes it feasible and not the driver of gps.
|
Re: PR 1.3 has improved GPS lock speed
The placebo effect was my first thought, but I've tried it several times and consistently have faster locks and I am achieving lock where I was having no luck before.
I am also certain polling (or whatever it's called) is more frequent. |

Sometimes is due to whether, clouds, satellites positioning in space, someday there are 3 or more satellites positioning is at the right location to communicate with the GPS chip. Sometimes because you using the Data connection and helps the positioning better than offline cold start. Just remember this, once you got a lock, the next time you wanting to get another lock is easier and faster than previously. In this case it is nothing more but a Placebo effect. It happenes all the time, it is all in your head :D, sometimes your eyes lied to you more than your friend did or your gf did. Sometimes when you desparately hoping for something better and your brain fooled your tought. Example: A soldier who get shot will not be able to feel the pain and will not know that he got shot. Not until he sees the blood and then he starts thinking about it, that's when the pain is trigger :) Simple comparision :) |
Re: PR 1.3 has improved GPS lock speed
used to take 15 seconds
now it takes 3 simple comparison |

Re: PR 1.3 has improved GPS lock speed
Well I'm as surprised as anyone. But I know what I see. I have always used the the Ovi maps and GPSJinni and there is a positive difference. All the doubters have said why it's not possible, is there any reason it could be possible? I can't find the change log to try to explain it myself.
BTW..... Poll added!:D |
Re: PR 1.3 has improved GPS lock speed
well, i think it's possibly unrelated, because others mentioned the agps server being reset back to nokia's from google's. i just rebooted and tried it and it's taking more like a minute now, but the whole phone freezes when the rtcomm stuff reconnects, so it's not really a fair test. But it's not really fair to test without rebooting either, it caches your last position... Good luck proving anything :P
Stupid closed source apps. |

Re: PR 1.3 has improved GPS lock speed
Nokia still haven't released an official changelog. In my search for one I came across another user, "I4U" here --> http://thenokiablog.com/2010/10/25/n...-pr-13-update/ He seems to be enjoying better speed too.
The more I use it, the more I'm convinced that Nokia have improved the GPS functionality. When my friend returns from Ireland with his N900 (running 1.2) I'll do some comparisons and share the results. |
Re: PR 1.3 has improved GPS lock speed
I don't use GPS every day, better to say regulary.
I'm sure there's no changes with the speed GPS locks. It was and still is pretty fast for me, I haven't noticed any changes since I flashed 1.3. Accuracy hasn't improved either(for me it's easy to check coz it never shows the right position when I'm home^^). And I've never changed supl server. |

Doesn't anyone else see the improvement?? :confused: |
Re: PR 1.3 has improved GPS lock speed
Its true for locks with activated AGPS. I get a lock in about 2 seconds at a new location (serveral 100km away from the last), Used to be about 15 before.
But lock without AGPS is still dead slow. I was in a position where I only had UMTS via Data-Roaming (=expensive) so I disabled AGPS. I had to wait about 15 minutes for a lock despite the device showing 10 recognized satellites after 2 minutes |
Re: PR 1.3 has improved GPS lock speed
Yes. Without AGPS is very slow. To get a lock on my n900 I have to wait about 7minutes minimum and usually even more. And I tested this not from inside a building but from outside where there were no buildings near me so it should be fast. And in GPSjini I can see that it found about 10 or more satelites and the signal on 5 of them is 100% but still it does not lock. I can not understand this.

Re: PR 1.3 has improved GPS lock speed
P.R. 1.3 seems to have a Ovi Map that actually retains the AGPS data so it locks much faster.
Pre-1.3 it always would download the AGPS data every time you started it up. Grossly inaccurate for me now though! |
Re: PR 1.3 has improved GPS lock speed
I thought this was wishful thinking on my part;
I rarely used GPS because we have next to no cell signal at home and Ovi Maps for N900 is all but useless for me. I tried the 'new and improved' PR1.3 version soon after reflashing and thought I'd accidentally activated the AGPS - the GPS locked on in about 5 seconds. Lat week I ran repeated tests both in and out of cell and there is definately a huge difference on my device. I can usually lock on within 3 secs and even get a good GPS signal indoors. Thus encouraged, I invested in Sygic last night and was so busy playing with it on the way into work I arrived late... I thought GPS was supposed to save you time? |
Re: PR 1.3 has improved GPS lock speed
Confirmed
:D I suspected most of these rumors of improved lock times are due to improved A-Gps arrangements but: I am in the middle of a jungle here and turned off A-GPS and just now witnessed cold-start lock in 90seconds. The unit had not been used for GPS in the last 48 hours so I am guessing they are storing the almanac. Previously under PR 1.2 I saw times of anywhere from 5 to 10min to get cold-start lock, which I guessed to indicate the system was discarding almanac information. I am impressed. Now that I have two units I am thinking I might try to set up a dgps arrangement if I can find the time to work out how to do it.:cool: |
Re: PR 1.3 has improved GPS lock speed
Hi everyone,
I have issue with Nokia Maps & Drive App. I update my N9 64GB (Product Code: 059J1V4) to PR 1.3 with a PC and I still can't use my Maps & Drive app because it stays in "Waiting for position" and the "Looking for GPS" forever. I had this problem since with the PR 1.0, PR 1.2 and PR 1.3, they stay in "Waiting for position" and the "Looking for GPS" and the navigation never works.. Only with PR1.1, I was able to run correctly the GPS. Any clue how to fix the problem? |
