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..

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.

Hi guys,
I'm a new user, and I just recently got my HTC Touch Pro/Raphael. I have some random questions that do not seem to be covered in any of the documentation I received with the device.
The only real question I have is regarding the GPS. Is there an internal GPS Antenna? Or do I need some kind of external peripheral to operate the GPS?
Also, having had a look around this place for a little bit, and noticed all the really pretty themes in the HTC Diamond area, do those themes work on the Pro?
And also, where is a good place to start looking for Windows Mobile 6.1 Apps/Games? I know there are quite a few Apps on this forum already, but I was curious to see if there was any sites available elsewhere.
Thank you.
You don't need anything to operate the GPS. Use an app like GoogleMaps and you will be able to see your location and navigate with directions.
The themes from the Diamond do work on the Pro.
You can find apps at pocketgear.com, or handango.com, or free stuff at http://www.pocketpcfreeware.com/en/index.php.
Hmm. It does have an internal GPS Antenna, eh..
I seem to be having trouble getting a GPS Signal, even when using the settings which are said to work with TomTom 6 (It is the GPS software that came preloaded on my Pro). I also downloaded and installed Google Maps, and that also cannot get a GPS signal where I live. I live in the middle of the suburbs in Brisbane, Australia, I should be able to get a GPS signal here. Is there some way of checking if my GPS Antenna is disabled, or turned off? Or faulty?
Or is the Pro just not very good at getting GPS signal?
Hello everyone,
I have a HTC Touch Pro since october 2008 but are still unable to use the gps with google maps.
Google maps is preinstalled on my device but can never use the gps to locate my position.
Now I heart something about unlocking your gps of you htc touch pro before you can use your gps in google maps.
This is the link: http://forum.xda-developers.com/showthread.php?t=490400
I don't know if this is suitable for my HTC Touch Pro too.
I hope somone can help me.
Thanks a lot!

what rom are you running right now? Assuming you're using a GSM phone, I doubt verizon's method would work for you. Try flashing a new rom.
Rom version: 5.05.404.1 NLD
There is no newer rom version.
I bought my HTC Touch Pro without a carrier, so my HTC Touch Pro is unlocked.
But I can't use my GPS with applications as Google Maps as long as my GPS is locked.
But I don't know if I can use the fix which is discribed in the link I placed.
In GoogleMaps: Menu > Use satellite...
and wait for a fix... (could last up to 4-5mn depending on reception conditions)
But before, check in GoogleMaps options that you have let Windows to handle (integrated) GPS.
Yea it sounds ass backwards, but what he said is true. If your turning it on hitting gps and you get nothing,, thats about right. Wait a bit and see what happens. I use my phone for geocaching almost daily, and am running the stock att rom. My gps works perfectly besides the fact that it takes around 30 secs to lock. However trying to run (most) third party apps WITHOUT googlemaps running first. It will just sit there all day and never get gps. (depends what program were talking about but most will never get lock until google maps is running)
what radio are you on?
Also, I had a terrible time getting a GPS lock with Google Maps on my unbranded Touch Pro.
Recently I downloaded the latest version from www.google.co.up/gmm (think that's right enter it into your Opera browser) and it has improved tremendously. No GPS locks a lot faster - less than 30 seconds, whilst previously it would take minutes or not at all.
Try downloading a newer version and see how that helps.
Thanks!
All of you!
I download a new version of Google Maps and installed it.
After that I set all the properties the same as I had under Start>Settings>System>GPS.
And after about 20 seconds I had a fix and it worked.
(and this was in house)
Now just at the street I get a fix in about 5 seconds and I have a log of zero until one.
So thanks all!
Hi,
HTC has released a new ROM for the Fuze.
Among other things, it contains an "A-GPS Update: Speeds up the time it takes the GPS to get a fix on your location", and "Quick GPS is still recommended for the optimal operation of GPS based applications and services".
Does anyone know whether it's feasible to implement only this part of the ROM in a Tilt?
My GPS reception is variable (using the internal GPS), no matter which ROM or radio I use (some are better, my current combination works best for me). The only way I obtai an extremely fast GPS fix is by using an external BT GPS (I purchased an GlobalTop G66 Plus, and I now obtain a fix within 10-15 seconds).
I have AGPS turned OFF because it doesn't work with IGO8 (had no problems at all with AGPS and IGO6).
I've tried every solution in the book and have carefully read all related threads here. None have worked for me.
So my question *only* refers to the suitability of implementing that portion of the Fuze new ROM.
Thanks.
I would think that you would be restricted by the hardware of the phone and not the software
Well, if you're referring to the incompatibility of IGO8 and AGPS, it's a given.
Hello everyone,
we are developing a location based app and reliable GPS fix is a must.
We were looking in the chinese market for Android GPS enabled mobile phones to test the app.
We finally ordered two STARB92 M however we realized that their GPS fix is a pain to get let aside the accuracy.
I know, there are lots of threads in this forum how to fix this issue, we tried a few and I cant say we got any results, Specifically GPS accuracy is still a mess.
My question is simple.
Are there any Chinese brands that offer Android mobile phones with out of the box reliable GPS fix (sub 10 meters accuracy, no flashing ROMS, downloading apps, setting NTP servers etc) ?
If yes please advise on specific models (requirements similar to Star B92M).
Your help is deeply appreciated - we are a step before buying external bluetooth GPS receivers .
Thank you.
GPS
are you sure you want GPS to be that accurate in China?
