[Q] Does Raphael have the same GPS lag as Diamond?

Hi guys,
I think the subject says it all...
I have a Diamond which suffers from serious GPS lag (not fix!). This means that when I'm driving, my car is always up to 50m ahead of what TomTom or IGO tells me that I am...
I'm thinking about changing my device as nobody seems to know the cause of this...
So, I wonder if Rapheal has the same issue or not...
HastaSSSS

Here's what i tested for you on the way to work...
Using TomTom6 (6.032), driving at 30mph, using the tip if the blue arrow as my position (same as i always used on TytnII) i would say my car was no more than 5m behind were i should be. No issue going down the right road or turn.

Same situation as johnk1973. No 50 meters lag, but aprox. 5 meters.

Same problem here on Raphael, TT7 is 50 meters behind. Will test it tonight if it also occurs with TT6.

Same here with tt7 and igo8....

Now this is going to get complicated....
I had Diamond before and NEVER experienced GPS lag.
I tried almost every official and cooked ROM and had no problems with GPS.
Recently I switched to Raphael....
And guess what... GPS lag !
I used my Diamond and Raphael in identical conditions, with the same app (iGO 8).
I'll try to test it more.
I'll post if I find anything useful to you.
Cheers,

Sh*t...that means Raphael is a "no go" for me...
Unless we solve the problem...whatever it might be...
Please keep on posting your findings about this issue...I like very much Diamond and Diamond Pro....but I'm not willing to have a device without 100% functionality...
HastaSSSS

I have a Touch Pro with iGo8 installed. I realised this "50m lag" on my business trip this Monday but I thought it was due to the speed of the car (I was driving very fast for the most of the time). Now I see the problem might be a little more complicated.
On the other hand the 50m is not so bad - I never had a wrong turn, the acoustic signalization of iGo8 is very good. Nevertheless, I would be glad if this could be fixed...
And another thing - I'm not sure if you are aware of the charging problem while using GPS. My Touch Pro actually stopped charging because of overheating and was running only on the battery. So be aware of this fact too.
But this is a different issue, I'm sure there is a thread for this.

I dont have the problem with TT6.

I second this issue, both with TT7 and IGO8 (haven't tried it with another one yet)

Guys I had GPS lag on TT7 when I fist used it (Only tried it for 5min) it was awful. Mainly everytime I turned a corner whilst driving.
Then I did the following changes:
\start\settings\system\external GPS -> Set GPS Program port COM4; Hardware NONE; Access Manage GPS automatically.
Hit ok, wait 10 secs, switch off the device and then soft reset.
Now go to TT7 change the GPS prefences, to use bluetooth device and selected COM4.
No my GPS is perfect now, no problems at all. Have tried it with two different ROMs and no problems.
I have TT7 installed on the main memory and the maps on an Sandisk 8GB Class 4 SDHC card.
Radio ROM is 1.02.25.19 if that helps? and AGPS is turned on a up-to-date.
BTW it was exactly the same when using google maps.

Did you also try it by just setting tomtom gps to bluetooth? I'll give that a shot anyway before going into the register... tnx for the tip

Please keep in mind that you'll get an update of your past position only once per second. This means: The faster your velocity the more inexact the position will be, because the distance you'll pass in this second becomes longer and longer:
@30kmph: ~8m
@50kmph: ~14m
@80kmph: ~22m
@100kmph: ~27m
@130kmph: ~36m
Additionally there is the inaccuracy which comes with GPS: In good times you may have ~10m divergence on average. But with weaker signal (which one may have driving in a city) it will become even more. So keep in mind that GPS will tell you, where you've been one second ago (plus the divergence).
By the time I get my Diamond Pro, I'll collate this at the same time with my X500, which has a build in Sirf3 receiver.

I am having a slightly different issue with my TP using iGuidance 4. Although the unit aquires a signal faster than any other device I have used in the past, it seems to lag or freeze as I drive. It will not update the time, speed or position unless I press a button or something on the screen. There is another thread on XDA (I think in the Diamond or Kaiser sections) that claims to have solved this issue, but the fix doesn't work on my Touch Pro (in fact it completely freezes my iGuidance requiring a soft reset).

Hi,
I'm using Ndrive and TomTom 7.
on NDrive I don't have any problem, it's fast.
on TomTom is slow..
I thing the problem is on TomTom using this GPS of Raphael.

these settings are the settings that are preset. Hence nothing changed. the lag on the diamond is bad but this is awful.

Using Igo8 very intensively with my TP, no lag at all. Compared it this morning with my VW passat stock nav system, and again, i notice no lag.

I have the settings in the posts above, and have very little lag. I am using QuickGPS instead of AGPS, but all else is the same. My main probklem is how long it takes to get a lock (much longer than on my old Kaiser), but since installing DCS's ROM and doing a hard reset immediately after that does seem to have improved - I often get a lock from cold within a minute now..
Rowan

I believe the reason that some people are getting horrible GPS lag while others get nothing has to do with the Radio ROM versions that came installed with the device. Most custom ROMS don't update the Radio ROM. It's 12am and I'm posting this from my TP, so I'll just tell you that the Radio thread is stickied in the Raphael ROM dev forum.

No fix !!!

I have a new RAPHAEL and do get no fix...I installend Quickfix and tried much but there is no fix ?
Any idea which can help - please ....!
Thanks

first fix can take a while. Make sure you are outside and leave the phone switched on with google maps or another app that uses gps. This can take over 10 mins before a lock is obtained. Quickfix is already installed on the device - no need to install?!

called QuickGPS (not QuickFix)

yep, same here just leave the device searching somewhere near a window or outside...it takes a while for the first one.

Really ...but how long 1 hour or more ????

Another question - I used the diamond tweak and after it the Rapha is faster but is there any other tweak which will fit better than he one for the Diamond ?

Does anyone know how to get the beamer at the right side thicker in order to scroll down ...

YOur first fix should aquire in under 20 mins provided that you are not inside your house and/or not surrounded by tall buildings. What application are you trying to get a fix with? If its google maps, you should see a series of dots followed by the number of satelites. The number represents the number of satilites that is using to get a fix, and therefore it will stay at 0 until it finds your position. There are also some tools on this forum that let you check the gps status discussed in this thread! http://forum.xda-developers.com/showthread.php?t=420933

ardsar - google maps is saying: 0 number of satelites.
I`m using "GPS Test" also and there I gt 3-4 yellow signs but in GoogleMaps itis only searching ....
It is really not my first ppc and many before wokd very well but here ???
Any other idea ?

Just go outside (take it on your next car trip to wherever) and use gps test or Google maps. At first I thought something was wrong with my gps but it just took a VERY long time (15 min - 20 min) to find my first fix. After finding my first fix, the next time I used the gps it seemed to find a fix faster. My bluetooth gps receiver I use for my other pda is 1000x better than the GPS in this device (it can find a fix within a building!). So just be patient. The touch pro will eventually find a fix. The gps is so far the worse thing I dont like about the touch pro (oh and no 3G support for North America).

3-4 yellow bars indicates that you are receiving data from 4 satelites, but have yet to get a fix. The device needs to download almanac data from the satelite which tells it where the sats are in orbit. Only then can it work out where you are. If you have a week signal or are in a building as suggested before, this signal can be very week and once it loses the data stream, it has to start again. It is important for you to be outside to get a good first lock and be patient, it will happen.

It is working - thanks so much for your help !!!

It is working - thanks so much for your help !!!

GPS fix confirmed and then some!

I know we are all hit and miss with the GPS, but after following a couple of tips out there GPS locks on Google Maps in 10-15 seconds, finally! And it tracks beautifully as well. These are older tips, but it is this combo that seems to work wonders!
I followed this...
http://forum.xda-developers.com/showthread.php?t=427888
(but change dPollInterval to 500 and MAxBufferSize at 256)
and...
GPS hardware settings:
Prgram port is COM4, no hardware port, and baud rate is 4800. I could not find the website that I got this info from so forgive me for not crediting you!
Google Maps is configured to let Windows manage my GPS.
After the GPS is "warm" it tracks in what relatively feels like an instant now! And it might just be me but it seems to find more satellites. I have a Fuze on ATT.

theres a bajillion fixes on here for gps. its just gonna have different results. easy thing to do is update radio to 1.12. though if you do that, dont change the poll interval from 1000 to 500. i found thats a bad thing in combination with it.

download the at&t test rom......fixed my GPS issues. Now I get a lock within 10 seconds.

the link above method works best when deltete gps log files and disable agps and using gps test software

I have to agree here.

Where may I find this ROM?

hmm
I must say . The updated rom from htc for the fuze pretty much fixed my gps (and made performance of the phone much better).

You can find it on blownfuze.org, but most of the newer roms have the aGPS fixed, so it is a lot easier to get GPS fixes

GPS problem with cooked roms

This is usual thread all over net..
I have problem, a big one... Every cooked rom I have tried works great but GPS dont work. Fix takes 15 - 20 min quickgps updates normaly but no fix... with original rom and quickgps updated fix is under 30sec but i have problem with touch screen on original ROM. so i have spend 15 days of experimenting, flashing various roms, radios but no luck....
interesting is that when i connect external gps antena with amplifier i get fix around 1 - 2min.... then it works with integrated, but 2 hours later same problem...
Kaiser130 is my device
tried roms: shifu v1 & v2 basic & full, Dutty's WM6.1, REV_ROM_V8, SimpleOsManila, AtheneOS....
also i have tried exporting registry branch from original rom for quickgps and copyed quickgps files over but no luck.
no luck

I have used almost all of these roms and my lock is in 2-3 minutes. 1st, make sure you are using the recommend radio. If you use the wrong Radio, you will never get a lock. Also make sure it is not just your area; if there are only a few sat's then the GPS module in the phone will take for ever for a lock.

C'Mon dude really... 3rd post and you come out dropping bombs like "every" and "it's the usual" and "a problem... a big one"
I have used many different ROMs here too and have not had a single issue with GPS working!
I think "every" and "usual" is disrespectful to the cooks here and that your issue is likely hardware (hence your comment about it working w/ an external ant) or possibly between the screen and the seat

have you tried gpstest to check your com ports and then set it manually?

I also had the same issues
already changed the com port and radio from 1.65.16.25 until 1.70.19.09 (KAISER Radio)

As u see raf1987 has same problem as me, yesterday I have tried original HTC WWE 6.1 rom but with same result.
I dont mean to disrespect cooks, and dont see what is problem with me having 3 posts??
k2rolla503 Yes I have tried gpstest, nonigps plot.... they find satelites but no fix 1 to 4 satelites all time but no fix.. signall strength is normal in all roms (graphicaly to me).

I too have the same problem.
I find the GPS fixes to be very flaky. I've used both the ROMs from Laurentius up through V10 and now using Phoenix II.3.
Laurentius ROMs I found I had much faster lock time if I downloaded the ephimeral file right before I used my GPS. We are talking 24 hours between uses. This could mean the difference between a 2 minute lock and a 20 minute lock. I've never gotten GPSTest to show me anything other than starting...
On Phoenix II.3, the ephimeral file only last for 3 days instead of 7 like Laurentius. Once I saw the fastest lock in my life ever on this ROM, it literally must have locked in 15-30 seconds. I have never seen it do that again. Currently it's taking me a good 10-20 minutes to lock on average. I have to start up my GPS 10 minutes before I go anywhere just to get it warmed up.
I've also tried fiddling with the assisted GPS setting on both ROMs. I found that with Laurentius the fix is slightly faster. On Phoenix I haven't noticed any real difference in getting a fix aGPS vs GPS. Nor do I find it assists in tunnels.
The only thing that really bothers me about aGPS is that I get that dialup connection dialog that says it fails to connect every time I use TomTom. I have to hit dismiss before it appears to start trying to get a fix. I've tried reapplying the connection settings for AT&T, that didn't seem to help much. It is super annoying.
In the end, GPS does work, but like the OP, I found that my fixes were consistently faster on the stock ROM than the cooked ROMs. I too mean no disrespect and I appreciate the hard work that goes in to each and every one of these ROMs even if I don't use them. I too like the OP just want my fix to be as fast as those claimed here and elsewhere. It can be frustrating to hear about these fast lock times and have to suffer with long lock times. It's especially annoying to me because I travel for business a lot and find that I am now nearly half way to my destination before I finally get a lock.
While I may not have many posts, I do follow these forums regularly. I hope that my input will be constructively used to find an answer if there is one to be found.

I have no issue using L26's TF3D V4, Athine OS Jan 22, Mbarvian Solace 1.5 and Josh' Revealed 21500. All has the GPS working fine. I'm not that particular that I measure individual response time.
As long as it locks within 1-2 mins (from nothing), it's ok to me.

hmm.... i think , i found the solution... don't know if it could work for others
now, I use PDA corner from Abusalza... with Radio version 1.70.xx.xx
so, after flashing your new rom... make sure you update the GPS support programs like quick gps , etc
then, execute your GPS program ( I use Garmin for this).. and make sure you are outside of your house, or apartment, or wherever..
the reason why my tytn II could not find satelites is because I did it in my house, did not think that outside my house could work (because my Trinity could detect satelites in my house without any support GPS program like quick gps)
then... your tytn II should detect the satelites and GPS is activated...
NB: sorry for my bad english

I am having the same problem. The original Three (Australian) ROM would get a GPS lock within seconds.Now, I take 20smins to get a lock.
ROM version: AthineOS WWE
ROM date: 1/22/09
Radio Version: 1.65.24.36
Protocol version: 25.94.40.06H
I have just used GPS test and the only thing I changed was the baud from 4800 to 9600. Will try it out later, but hope it works.
http://www.smartphone.net/software_detail.asp?id=3170
PS Most of us know that GPS works only if there is line of sight with the satellites, so yes, I am outside on cloudless days when I try to get locks.
PPS If it dont work, I might go back to official ROM. http://www.htc.com/au/SupportDownload.aspx?p_id=13&cat=2&dl_id=342.

flash back to WM6.0, there are no problems with gps. every fix in 30 sec.

Hmm I would like to go back to 6.0 but my provider has only this rom 6.1 for download that has touch screen problem...
Any link to 6.0 WWE would be helpful

Found 6.0 sry.... ill try and post reply

Search the Wiki. There're links to various WWE versions.

Hmm, I wonder then what the difference is between 6.0 and the higher version that causes this inconsistency in locking. This would seem to indicate software issue rather than a hardware issue. I love the newer ROMs but the inconsistency or complete latency in getting a lock can be extremely annoying especially when you need a lock quickly.

I changed the baud from 4800 to 9600 and so far, the GPS locks within 30 seconds. I need further testing, but perhaps the default settings of the cooked ROMs is causing this problem?

I have tried and sucesfuly cooked ROM from stock firmware, added some apps, replaced buggy touch.dll so far so good ROM is 6.1 (WWE 3.31.xxx) using radio 1.65.20.15 i think.
Yesterday cloudy weather with rain i got lock within 4min cold start after flash, today morning warm start 2min (still cloudy no rain) and around noon no clouds got lock in 5sec.
Big THANX to SHIFU for help with dll

help with dll?
hi Vratko,
could you provide more info on the dll that u got helped with?? cos as u can see, lots of us are facing the same problems....even i have tried all sorts of ROM's and radios....yet no success in getting a quick lock...any specific settings to be done?? any

Hi,
I have different problem on GPS, I am using Garmin DK Series, dated 01/16/09. The problem is if use GPS for more then 10 min, back of the kaiser started to heatup, if I turn it off, after a while it is fine. Otherwise, it is detecting the GPS faster. I have downloaded QuickGPS & SeaSGEE.
Is anyone having these problem.
Thanks

Can you please provide SeaSGEE link. What does it do? is it like quick GPS?

[Tweak]Superb Fast GPS Fix!

Hello all,
I am writing this topic to let you all provide of this super tweak! Here I show you how to get this fix. With this tweak I got a gps fix within 10 seconds(under clear sky), better, more, faster satellite fixes.
First I used this tweak:
http://forum.xda-developers.com/showthread.php?t=427888
(I suggest you to first hard reset, and then apply the tweak. But I guess it will also work right if you don't) Do everything EXACTLY like the tweak says. If you don't do it right. It might fail.
Next tweak.
I found this tweak when I was searching for tweaks for my Samsung Omnia. I found this application. I have tried my gps first before installing this application. It was a weak signal and I could only find like 4 satellites and it took me like 15 minutes to get a fix. But when I applied this application, I got a fix withing 10 seconds!!! And with at least 7 satellites!! Here is the application;
http://www.mediafire.com/?zilthagdhey
Settings:
In settings/system/External GPS, The GPS Program port is COM4, No Hardware port and a Baud rate of 9600. In GPSModSettings(Found in main program folder) I have set; log file, Extended, Smooth to blank marker, Sleep time 1000 GPSModDriver to Comport 1 and enabled.
Then scroll a down a bit for the next settings.
GPSID External GPS to Com Port 4 and enabled.
Congratulations, You have done the tweaks now! I hope it works right for you guys and good luck with navigating!
PS I am using radio: 1.02.25.32.

What application??????????????????

Sorry, I edited it.

anyone confirmed this???

You could try it yourself. The tweaks are just default. So that would be thrustable.

Is the test really valid ?
Once i have a fix in an any application (no matter how long), if I quit then start another application and use the GPS, i got a fix in 10 seconds. Wait a few hours between your tests

no wayyy to be so.....
guys it is only me who didn t get this,or u still don t get the picture.GPS isn t need a fix.The phone is **** as it comes out the HTC factory.BUT!!!
u need a new radio rom,and no more problem with GPS I personaly use TAE rom and since that moment my GPS problems are past!!!!
So if u have time just create fixes,but .....WHY?? Flash and enjoy!!
helios (who read other posts and learn.No fixes)
