Fellas and ladies,
I have heard good things about this phone (the OZ variety anyway). My question pertains to the GPS chip. Is this chip comparable to the SIRF-III (or something similar) in MIO A701? How is the reception/accuracy in the major cities? Melb, Sydney, Perth in particular?
Is there a "better" unit coming around the corner soon-ish? Ideally FM tuner would be good.
Also I am looking to ebay a bluetooth handset. Any cheapish (<$50-60) ones worthwhile spending molah on?
Cheers
I don't have anything to compare too, but use in suburban Melbourne with TomTom and was blown away by the accuracy.
Also even have it working indoors, where another GPS device we have at work requires an external antenna outside for it to work.
A few years ago I had an external GPS receiver by TomTom. In my car (with nice dark windows) I could only get a fix if I held the receiver near the sidewindow, no fix at all anywhere else in the car. With the Trinity I can have the device anywhere I like in the car and get a fix all the time.

It is not a SIRF III Chip but a Qualcomm Chip. I have the TomTom Bluetooth Mouse Mk-II which has a SIRF III and performs slightly better than the Trinity. I will sell that Mouse anyway, cause the difference is so small that I prefer not to carry 2 items around...
Comparison of several PDAs with internal GPS units here:
http://www.gpspassion.com/fr/articles.asp?id=175&page=6
Including both the Mio A701 and the Orange M700, which is the Trinity by another name.
Basically the conclusion was that the Qualcomm chipset used in the Trinity is not as good as SIRF3, but is not too bad.
I have a BT SIRF3 module (purchased before the Trinity) and I haven't noticed any significant difference in performance between it and the Trinity internal GPS. Though I'm not working it that hard - mostly using it in suburban, open type environments where a GPS lock is not difficult.
Thanks fellas... I was also trying around melbourne suburbs with excellent success... It also locks to GPS indoors (takes a while though)!!!
The only drawback to the Qualcomm is that it takes quite some time to get a first fix (cold start), and even forget about getting a fix at all if you're already moving around...
The performance when it has a fix, is truely remarkable though. Worth of notice; because of the Qualcoom performing the GPS, the GPS won't work if you have the phone shut down...
Googling and searching these forums doesn't bring up anything obvious. So does anyone know what chipset it uses? Looking at logged data it is operating at 1Hz.
It's built-in the Qualcomm Snapdragon chipset, see here
Thanks. I'm just trying to work out if it will do as good a job as my external bluetooth sirf III one I used for racetrack lap timing with my previous phone.
For normal navigation the inbuilt GPS gets fast lock and seems to work okay but the more accuracy the better for the track.
Guess I can just run it and compare times to the electronic timing (which take 1-2 hours to be printed out and released hence the need for an instant solution).
it's the best inbuilt gps ive used gets a lock in under 10 sec my xperia used to take 30s to 1 min.

The SiRF chip is better than the GpsOne on Qualcomm SOCs.
And to above post, this might be because AGPS is actually working on this phone rather than the antenna being better.
dont think i have agps enabled if im correct it uses data, when i start igo 8 no connection is made, im just using antena.
my device recives signals even if iam in home and recives at least 3 satellites

it will be down to how fast/often the app polls the gps surely?
I've been playing with it a fair bit (for the same purpose) and it certainly better than one or two stand alone gps
Getting satellites indoors or getting a fast satallite fix does NOT automatically indicate that the GPS chip is good.
Actually GPS on the HD2 is pretty poor compared to the SIRF III chip, or even compared to other HTC devices, I am talking about accuracy and stuff. This is a fact, so i don't want to hear any more about "how good it is because it gets a fast fix" or other crap
For more info:
GPS going crazy (proven with plot screenshots)
Weird GPS problem. Moving even while my car is motionless.
Recent ROM/Radio for the HD2 upgrades do seem to improve this bad GPS functionality though.

I understand your viewpoint, actually I had such information (plots of the HD2 and of other devices), but I really can't be bothered to make them again and spend all the effort on it... just believe me when i say it (or don't believe it, i'm just sharing what i know)... or have a read through the topics i linked to (should be enough proof in there)
Well if I have time I'll try both at the same time this weekend at the track (still have my old phone and external GPS).
With the high speeds involved and a racing line that varies no more than 1-2m it becomes pretty easy to tell if the GPS is out when plotted on a track overlay.
Plus values for lat/long g forces and speed are all extrapolated so if these are out it becomes pretty obvious.
Hello everyone.
I am going to buy htc desire soon. I have a query to ask. Please help me on this.
How would you rate the GPS on the Desire if i am going to use google maps? As is the speed. The screen view-ability etc.
The reason I ask this is that if it is not that good then I'll buy iPad 3G else the wifi version. I am really stuck with the decision. Please help me on this.

I am not sure about using it with google maps, but I have copilot and it works very good with that.
Also, comparing with HTC Diamond's GPS, the GPS in Desire is much much better. It locks the location even faster than my old Garmin Nuvi 350 that use sirf III.
The GPS in Google Maps is pretty spot on, and also works very well for Google Navigator too. The lock speed with assisted GPS is probably the fastest I've seen in a phone. Certainly better than my previous HTC Touch HD.
I've used 5 different HTC Devices with GPS Receivers throughout the years and the Desire beats them all. Time to get a fix is nearly 0 (Well okay, but it is veeery fast) and also very precise. Using it with google maps and Mobile Navigator and have never been happier with a GPS Device. Scrolling the Map in Google Maps is the smoothest i have seen on a mobile device (it is easily as fast as the iPhone, personally i think even faster) and it never loses the GPS Connection. I made a trip with my bike the other day, Desire in my Jacket and only took it out every 10 minutes or so, when heading towards an intersection where i had to turn and didn't know where to ;P It wakes incredibly fast from Standby, the Fix has never gone and your position is acurate again in an instance, not lags at all.
Yes, I can confirm all above, also sensitivity is excellent, I was able to fix inside my living room 3m far from window
+1. I use an app called GPS Test which shows you how many and where the satellites are you're connecting to. Also gives speed info. I'm shocked how quick it locks onto satellites. I use in on the bike and car with no problems.

Can anyone confirm how the "stand alone" GPS works by itself? What if there is no mobile data coverage available?
Stand alone gps is even better as long as u have good navigation software installed with maps. Like co pilot, motonav (igo for desire.). It's almost instant... well worth of money. Paid

Can also confirm that the GPS is superb. GPS Test from the market shows you number of satellites used & degree of accuracy. My Desire stabilises on 2-3m accuracy I'd hazard that stand-alone GPSs won't do any better than that, and I've only seen it lose GPS signal once... for about half a second.
Coming from a Touch Pro, this thing's GPS (along with absolutely everything else!) is a revelation!
I'm an avid cyclist, use the Desire with runkeeper & sportypal, it is spot on accurate with my rather expensive & well tuned bike computer.
I also use it with copilot and it works perfectly...

I usually get a lock when outside within 10th seconds maximum, compared with about 3 minutes on my Omnia without tweaks.

When You are roaming then MB prices are very high... so I understand using google maps is working great when You are in your home network.
What other GPS software (with maps stored on the Desire, not downloaded in real time) have You used and was it any good?
i think my old Hero was faster, but i could be i imagine it... Will traveling in high speed affect the lock time?

It won't be an issue upto 140 MPH, I can confirm that. Faster... I'm not sure. I've used the GPS facility for routes and disabled my TomTom over 60 times by now. Never once has it failed signal or lost tracking (in the UK).
I can confirm all the above positive sayings. Apps like Car Home / Navigator will assist you well. The GPS Test app is excellent (I use GPS Speedo and GPS2GoogleEarth at times too).

hi mates!
i am a newbie here
i use my desire in Greece so i want to know how i ll find CoPilot 8?
if i search to market there are no effects
Why has this been brushed over? Is GPS ironed out here? From what I can tell, Samsung has a horrible front end for their GPS with the Galaxy S line and a weak/insensitive GPS antenna to boot
I don't have a Galaxy S to compare, but on my Tab it seems to be working just fine. Better than on my G1 even. I just got six satellites and a very quick lock, and I'm currently indoors, just sitting next to the window(yes, writing this on the Tab).
Yep mine is just fine. I keep agps off in Google maps and its very accurate - more so than my moto milestone.
EDIT typos.
No GPS issue. This have been noted in preliminery reviews all over the web.
Size matters
Wonder if it has a different chip inside than the galaxy phones. If not then we can probably port the tab OS to the galaxy phones.

Yes, the Tab does appear to have a good GPS function. I've got the Tab sitting next to my Galaxy S near the window at the moment. The Tab can see 7, with a lock on 6; the Galaxy S can also see 7 with a solid lock on 4.
Coincidentally, I did a 'wardrive' test on the tram ride to work this morning. The Tab was tucked comfortably into the inside pocket of my heavy winter coat, producing good results.
Mind you, I've also had pretty good results under identical conditions from my Galaxy S.
I don't quite understand the recent fuss that seems to have been made concerning the strengths and weaknesses of the Galaxy S; after all, it's simply a GPS-enabled consumer grade handset.

Hello...One question if I may:
Since Android (eclair and froyo) doesn't have proper or at least clear connectivity control, how do you make sure agps is off and why do you keep it off?
Just curious......

Please! Let him answer.... it's about A-gps (full assisted gps -SUPL) and nothing to do with the internal gps receiver.....
.
I'm pleasantly surprised by how good the internal dedicated GPS receiver is. I have an external bluetooth GPS unit (Sirf III) but I will probably not need it with the Galaxy Tab.
As for the A-GPS feature, it can easily be switched-off completely via the system settings panel.

Where exactly in settings?
Location and security ( wireless networks) ?
In the froyo I have (JPA firmware of the sgs) there isnt a clear a-gps settting/key to disable like in the Symbian Os for instance....

Believe it says check here if you want to use wireless networks for location.
I was amazed at how fast mine got a lock in downtown Vancouver, my Galaxy S (and my Milestone and my Blackberry and my...) all too quite awhile to get a good fix when surrounded by office towers, the Tab is much faster.

That's not aGPS.
I'm happy to hear this anyway. The GPS on my current Vibrant is OK, the ones I had before we're pathetic though.
I have a Captivate and just picked up the Tab for Verizon. I have to say that the Captivate's GPS is fickle at best, but it is a completely opposite with the Tab. It locks on immediately when I am outside and at most 15 seconds indoors. I really hope it is a software problem, but I also wonder if they both have the same GPS antenna. It scares me that it might actually be the Captivate's hardware if they aren't the same.
I'm pretty sure the Captivate uses the metal back for it's GPS antenna. The Captivate's I tried at the AT&T store locked on pretty quickly, no test of tracking accuracy of course. I have my old Vibrant next to my New (but obviously previously owned) Vibrant and the GPS is obviously much better on this new one I have now.. SNR's are much higher, it's picking up more birds and when navigating my old one gets big circles around my location and often blips up on accuracy.
The CDMA/GSM-WCDMA versions have different GPS receivers. I know for a fact that the GSM-WCDMA Galaxy S and Galaxy Tab share GPS receiver chips so it should be the same for the CDMA versions.

If you are getting a lock indoors, it have nothing to do with antenna, etc. but with full a-gps (supl) wich I don't use.
Btw I use only onboard/offline gps navigation programs.
And I go online only via wifi...

Neat!! Thanks!
Based on my gps experience with the sgs international, I can say that eventhough the Broadcom chipset is not that dependable on full agps (supl)support, it's still much less capable than sirfstar chipsets....

GPS sucks on the Galaxy series. They apparently did not fix this on the new Nexus S, which is the same hardware just about.
Mine does not suck at all .

mine works perfect !!!!!!!!!!!!!!!!!!!!!
What, there's a GPS on the Galaxy? You serious?
Seriously, have you tryed searching a little bit?

I find it quite "usable" these days, but I strongly agree it could be MUCH better. I get dropouts quite often when driving, and in comparison, my years-old Forerunner 305 seems to produce more consistent tracks when jogging.
I find it suspicious that those here who speak of the GPS as "excellent", never post any tracks showing it too.. So I can only assume the GPS is poor for everyone

As i have said before define usable and poor .
Quick lock without WiFi Driving GPS works .
Route tracking as near as i would want bearing in mind that my route tracking would be car use . Walking route tracking had no problems when i tested it .
I have posted tracks but their was no response .
GPS as good as my Nokia 5800 was and not as good as a Tom Tom stand alone GPS unit .
Not bothered to test it against my laptop and sirf kit .

Since switching to cm7, gps is great as never before.

Why don't you take this on the 500+ post thread on GPS?
IMHO, Every aspect of this situation has been covered.
I use the GPS up to 5 times / week to track my runs, it gives me precises speed and trajectories.
Want proof? Search for the other thread and ask in, I might post my track on the right place...

10 sec full lock
I'm in no way saying the Galaxy's GPS is better than the Desire but........last week I was on top of a mountain skiing with my mate who has the Desire, I got a lock and good tracks with accurate average speed and so on he did not. My Galaxy locked within 10 seconds while the Desire took about 3 mins and then gave inacurate results. I was using Sports Tracker he was using Endomondo.
I'm now reasonably happy with my Galaxys GPS performance although I know it's not the best.
