[Asus  Eee Pad Transformer Prime] jdbaker82:
Never heard of a gps even taking over a minute to lock so anything over that is broken in my opinion.
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
In my Wi-Fi example, GPS was already locked before GPS Test even started.
[Asus  Eee Pad Transformer Prime] Diamondback:
Well it's the theorethical maximum. My first mobile phone with GPS didn't have AGPS, so a cold boot did take quite a few minutes... Not 12 but around 5 ;)
[Asus  Eee Pad Transformer Prime] skeptikal:
Just tried mine in a windowless room inside my house (a thanks goes to the first to guess which room that might've been...lol) and I am happy to say that I got a fix on 7 sat's in less than a minute. My office is in a law enforcement agency so that may be why I couldn't find any there. My house is framed with bricks and stucco.
[Asus  Eee Pad Transformer Prime] arcticreaver:
i think most people will be using their tablets indoors and from the looks of things in this thread, ASUS has a definite problem on their hands.
[Asus  Eee Pad Transformer Prime] demandarin:
this might be just like my Ipad then. only 3g versions had a true GPS in it and wifi had an Agps in it. there was a huge argument in Ipad forums over this. because people with wifi versions were saying we had a true GPS unit also based on it being able to locate so well. thing is the Agps uses some kind of traingulation method based on wifi locations. as long as wifi signals were in air wherever u went, more than likely wifi only Ipad could locate you and track you. I confirmed this in my wifipnly Ipad also as I traveled and it tracked me the whole ride and gave me speed I was going. 3g ipads have GPS but uses it on addition to the Agps for a more accurate pin pointing. its using triangulation of GPS, and cellular towers to find its location.

maybe its the same for the prime. maybe Asus tried to use Agps as saying device has GPS. because Agps is a form of GPS. that'll be really slick of them if this is the case. not sure. just thought I'd throw that out there.
[Asus  Eee Pad Transformer Prime] jdbaker82:
Good stuff so is it possible everyone on these forums has been overlooking this the entire time? Chime in fellas.
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
I thought that at first too. But it wouldn't be able to get a GPS signal at all without Wi-Fi if that were the case. And (I think) some people reported being able to lock satellites without Wi-Fi. Like I said in another post, my Vaio P has to have broadband on to use GPS because they're on the same chip. Maybe it's the same with the Prime with GPS and Wi-Fi (on, but not necessarily connected)?
[Asus  Eee Pad Transformer Prime] RussianMenace:
Weren't there some that reported their Primes locking on satellites in GPS status/ GPS Test? Or am I starting to lose it and just making crap up.
[Asus  Eee Pad Transformer Prime] jjj666:
I just received my unit today. Tried it. If not turning on the wifi, it doesn't lock within 2 min I tried, but if I turn on the wifi, it locks in about 30 seconds.

Is this normal?
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
In the second video I posted above, Wi-Fi was off and it locked on 11 satellites in less than a minute just using the GPS chip and nothing else. That's pretty normal. With Wi-Fi on (and connected) accuracy is improved because in addition to the GPS chip, s/w is using network resources to receive additional location data. GPS data received over W-Fi is called aGPS (assisted GPS).

Any device with a GPS chip in it should be able to receive GPS signals with no additional help. It seems the Prime's struggling without being connected to Wi-Fi.

The question that's being asked now is if the Prime needs to have Wi-Fi on (even if not connected) in order for the GPS chip to be active and receive a signal.

There, you're caught up. ;)
[Asus  Eee Pad Transformer Prime] Diamondback:
This is the only thing which

could

make sense at all...

There is no real reason why you need to be

connected

to a Wifi for the

A

GPS part in order to receive GPS signals...

The GPS signals have nothing to do with Wifi. So there can't be a hardware relation between those.

Only possibility would be that Wifi needs to be turned on, which would be a huge flaw, but maybe fixable via firmware upgrade.
[Asus  Eee Pad Transformer Prime] Diamondback:
Not sure if this makes sense. I don't think the

A

GPS part increases accuracy in normal GPS chips... Only the TTFF afaik :)
[Asus  Eee Pad Transformer Prime] demandarin:
true, that's what I'm thinkn. shouldn't be able to connect at all

yes, there are some who confirmed theirs working. the only thing is we don't have a set baseline of testing methods to compare off of. people doing different things to test. some downloading agps data first, then testing. some aren't downloading the data and then testing. so there's really no control based method of testing to confirm. everyone using different variables which could be affecting the final results. srry if i got nerdy on ya...lmao :D
[Asus  Eee Pad Transformer Prime] skeptikal:
Would it help if I post a vid of locking sats in airplane mode in my house?
[Asus  Eee Pad Transformer Prime] nxp3:
It advertise as having GPS (global positiony system) that means it should work anywhere on the planet. If it's near wifi access point only, then it should be called WPS (wifi positioning system). G is for global....I don't know who the hell starts using cell tower triangulation to mean GPS, but it's not. Neither is wifi triangulation.

Don't forget this isn't the first time asus screwed up on their wordings? If you read the manual, you will also see that they said Stereo sound. No where on the prime does it have 2 speaker for stereo sound.
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
You'd probably no better than me. Since they work in tandem, maybe aGPS is used when the GPS chip is struggling.

Are you sure about the h/w thing? My Vaio has a combination broadband/GPS chip and they don't really have anything in common. Maybe to save money, Asus is using a combination Wi-Fi/GPS chip? I'm only guessing.
[Asus  Eee Pad Transformer Prime] DaRacerz:
Those reporting GPS at 145 accuracy makes me think its really coming from assisted wifi location and not from the GPS network. If a good lock was made in clear sky's and no skyscrapers around I would expect at least 5 satellites and better than 10 meter accuracy.
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
What are your results from a cold boot? Once you've locked, you should stay locked and everything after that should be pretty clean and fast. And from what others have posted it seems a lot easier for the Prime to keep a lock then get a lock. A good test would be to put your device in airplane mode and then cold boot it and see what the results are.
[Asus  Eee Pad Transformer Prime] Diamondback:
No, just saying that i don't see any chance we need intentionally a connected Wifi to get GPs

signals

(This is what several Asus reps said)

I think this statement is totally wrong.

There

is

a chance that Wifi needs to be ON for a combined(?) chip to work.

But as you showed us that you get a lock without Wifi this seems to be wrong too.

I think that Asus may have opened a lot of Primes to fix the second Wifi antenna and in this process they may have destroyed other things like the GPS antenna...

I mean getting

no

GPS signals at all is

really

strange... This is neither a design flaw with the metal backing nor a softwarebug...

This really seems to be hardware related...

I guess we'll see once Europa gets their Primes which should be a later batch than the american ones.
[Asus  Eee Pad Transformer Prime] demandarin:
makes sense.

that would be a good test. this thread is getting more n more interesting with all this testing and troubleshooting Asus is putting us through. its like we are their QC department..lol

they need to just come out and address all issues once and for all. they know what day hell is going on but keeping lips shut on it. this issues are seriously starting to taint what is basically a great device we have. Asus just needs to give all of us with initial preorder units a free dock keyboard and 32gb. memory card along with fixing the problem. then it'll be all smiles :)
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
Can or has anyone gotten a GPS lock in airplane mode from a cold boot?
[Asus  Eee Pad Transformer Prime] dsmitty166:
Just tried GPS on my new prime from best buy. Got an instant lock in maps. Accuracy to 20meters in the basement of our house. I usually cant even get a lock on my phone.

Edit:should have read farther back, seeing as it seems to be working for others on wifi. My bad
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
Fabulous. Was it with Wi-Fi connected? If so, that hasn't been as big an issue. Put it in airplane mode, cold boot it, use GPS Test, and report back.
[Asus  Eee Pad Transformer Prime] tbns:
Just tested mine in Google maps. Locks immediately, and my location is quite accurate. I also updated the firmware.
[Asus  Eee Pad Transformer Prime] joepic:
Please take the POLL and put a YES for your testing of the PRIME:)
[Asus  Eee Pad Transformer Prime] xGary:
Looks like Asus delayed it and still didn't fix anything

[Asus  Eee Pad Transformer Prime] sambow87:
Is it using GPS or Wifi for location? Because mine was only using Wifi and searching for GPS.
[Asus  Eee Pad Transformer Prime] nxp3:
What is your damn point, we are trying to see if gps is working, not buy routing software.
[Asus  Eee Pad Transformer Prime] tdrussell:
Why, because 3 people are having a GPS issue?

DroidX | XDA App
[Asus  Eee Pad Transformer Prime] jzen:
Sounds like to me that everyone is having the GPS issue. I just got mine today and yep... GPS not working (went outside).
[Asus  Eee Pad Transformer Prime] xmtsystems:
I tried mine earlier today, and it wouldn't connect to gps via google maps, however as soon as I downloaded GPS Essentials it started locking onto satellites. I think there are still some issues with it though, because the most accurate reading I could get was within 80 meters, which sucks royally. I'm going to contact Asus tomorrow and ask them about it.
[Asus  Eee Pad Transformer Prime] tdrussell:
Uuuhgg seriously?

DroidX | XDA App
[Asus  Eee Pad Transformer Prime] kristovaher:
I totally saw this coming ever since the WiFi issue became apparent. It's the metal body, it won't lock on to GPS. They did not think this through at all. Thankfully GPS is not that huge an issue compared to WiFi, but it is still a major thing to a lot of users, especially when using it as a navigation tool in cars or for location based services.
[Asus  Eee Pad Transformer Prime] arcticreaver:
hopefully the issue can be resolved.

but also, i think it's time to start up a bug thread with all related bugs with the prime.
[Asus  Eee Pad Transformer Prime] BiGMERF:
anyone take to gplus and or facebook with the issues?
[Asus  Eee Pad Transformer Prime] nxp3:
this really sucks

I just found out now that I can pick up my prime at gamestop and this is holding me back. I need more tests than 5 people with 3nos and 2yeses.
[Asus  Eee Pad Transformer Prime] jzen:
Yeah they definitely failed at trying to copy ipad 2 with the metal body thing. One thing apple did was use their heads when making the metal case by adding a plastic apple logo to the back of the device and having the wifi antenna right behind it so that it gets good signals lol.

I dont think they will be able to ever fix it, but maybe if you send it back to them they can add another GPS antenna?
[Asus  Eee Pad Transformer Prime] tdrussell:
Do you guys honestly think Asus designed a device with non functional GPS? The wifi issue was a manufacturing defect, nothing to do with the metal back.

DroidX | XDA App
[Asus  Eee Pad Transformer Prime] arcticreaver:
if apple can fix the death grip issue with an update, i think asus should be able to do the same.

hopefully soon.
[Asus  Eee Pad Transformer Prime] jzen:
Actually if you do your research, its not a defect. It has everything to do with the metal case. They recalled them and installed a second wifi antenna to help remedy the problem but its still weaker than TF101 according to reviews that did in-depth testing for this.
[Asus  Eee Pad Transformer Prime] desert_mouse:
Actually the problem was the second antenna wasn't working. They didn't install a new antenna, it was already there.
[Asus  Eee Pad Transformer Prime] tdrussell:
Oh. My....

Yeah they just slapped a second wifi antenna in there.

DroidX | XDA App
[Asus  Eee Pad Transformer Prime] jdbaker82:
This is interesting and I am wondering thesame thing.....although for all we know the problems have been with the GPS all along but maybe its a wifi/GPS combo so they just said wifi delay. REGARDLESS what good is a posiitioning system if it has to be connected to wifi it makes no sense and if thats what they are being told to tell people just to keep ignoring the issue that really just pisses me off more.

On a side note this touch screen is really starting to piss me off seems like i have to press way too hard and have to hit spacebar more thenonce orthis keepshappening.....
[Asus  Eee Pad Transformer Prime] tylermaciaszek:
Went into airplane mode rebooted went into navigation couldn't find location....
[Asus  Eee Pad Transformer Prime] skeptikal:
I'll try it now. I bet you are right. They are coming up quick but I haven't rebooted. I'll test now.
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
Try turning Wi-Fi on, remove your AP from the connection list so it doesn't connect at start-up, cold boot, and try again.
[Asus  Eee Pad Transformer Prime] dsmitty166:
Just edited my post above. Downloaded GPS status and no sat's yet. Oh can I say I love this thing so far!
[Asus  Eee Pad Transformer Prime] tylermaciaszek:
What are you talking a about? I said I could not find location
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
Wi-Fi (even if not connected) may need to be on for the GPS chip to be active. It's just testing a theory that there may be a Wi-Fi/GPS combo chip or that they share antennas. If Wi-Fi's connected you'll be using aGPS but if WiFi's on and not connected it'll test the theory that they're somehow tied together.
[Asus  Eee Pad Transformer Prime] tylermaciaszek:
Oh we have agps because I was using GPS fine until I did a cold boot inn airplane mode
[Asus  Eee Pad Transformer Prime] nxp3:
That's not true, if you turn wifi off and go outside you still get a satellites but only a few seconds or so....proving once and for all that you don't need wifi for GPS to work.
[Asus  Eee Pad Transformer Prime] jdbaker82:
ok so the latest joke excuse asus just gave to my father is that they did not have enough flash memory to store the gps maps so they wanted to give customers a way to still do navigation but they have to do it through tethering with wifi (cell phones) I am absolutely disquisted with ASUS and am returning mine this company had my respect but they are really tarnishing their brand with this ball drop.
[Asus  Eee Pad Transformer Prime] racerex:
I felt compelled to register and post because I see a lot of misinformation here. Let's get a few facts straight...

-GPS does not require the use of a WiFi(802.11) or cellular(2G/3G/4G) connection to get a first fix

-Some implementations of GPS have the capability to use WiFi and/or cellular connections as an option to help speed up time to first fix. This is called AGPS and only affects time to first fix.

-Accuracy of GPS typically does not increase with WiFi or cellular connection. In other words, once a fix is obtained, GPS accuracy is the same whether WiFi or cellular connections are present. I say typically though because there are some advanced systems that use off device servers to do some heavy computations and then relay device location back to the device through WiFi or cellular. I doubt this is the case with the TF201.

-Some devices have no GPS and just use WiFi or cellular data to provide a very rough (e.g. 200m) location accuracy. THIS IS NOT GPS.

I believe the TF201 has a GPS system that uses WiFi to help speed up time to first fix. That said, WiFi should not be required in the TF201 when trying to get a first fix, and the lack of WiFi should only extend the time to first fix.

Given the symptoms people are reporting, and the fact that it is not consistent from device to device, I also believe the problem plaguing the TF201 is hardware related and specifically related to the GPS's receive sensitivity. Perhaps there is some variation in antenna impedance from tablet to tablet. This could be caused by something as trivial and devastating such as manufacturing intolerances that cause the aluminum metal casing to inadvertently touch an antenna and screw up the receive path impedance.
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
If some people are able to get a GPS lock in airplane mode from a cold boot it'll prove the Prime's GPS chip is working and capable of working alone. If no one can, that means there's something's really funky about how Asus implemented GPS in the Prime. The things I'm asking people to try are just to narrow down the problem and see if it's universal.
[Asus  Eee Pad Transformer Prime] skeptikal:
I just tried from a cold boot in airplane mode and got no sats. Forgot my router, rebooted with wifi on no internet connectoon and got no satellites. I'm going outside in airplane mode and feel certain i will get sats and a fix. BBIAB
[Asus  Eee Pad Transformer Prime] tylermaciaszek:
My question is who cares if we have GPS or agps it still works correct? Sooooo who cares Asus said we get GPS and we did so get over it
[Asus  Eee Pad Transformer Prime] skeptikal:
Outside, in airplane mode after a cold start it took less than two minutes to find 14 and lock 8. I don't find any indoors unless I have previously locked as Barry suggested.
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
Excellent post. You should stick around. If you read back, there's not a lot of commonality in what people said was and wasn't working. Some fixed via aGPS and the Prime maintained a fix but with no reporting of how solid that fix was or how consistent the readings were after Wi-Fi was turned off. If some people can get a fix in airplane more after a cold boot that will at least prove the GPS chip’s working. If some can and some can't it proves the chip itself is defective. If everyone can get a lock with Wi-Fi on and not connected that means, even though it's unusual, Asus has somehow tied the two together. If it were black and white there wouldn't be 30some pages of pretty circular discussion.
[Asus  Eee Pad Transformer Prime] jdbaker82:
The point is it does not work unless you are connected to a wifi network now I dont know about you but i know how to navigate from my bedroom to my basement and dont need a GPS for that.
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
A GPS dependent on Wi-Fi isn't GPS. And, if that's the case, people should know that before they purchase because, while obviously not important to you, it may be to others.
[Asus  Eee Pad Transformer Prime] tylermaciaszek:
Some people might not know how to and if you bought this tablet just for GPS then why did you do that. Asus never said we would get full GPS don't think they ever mentioned gps.I'm just saying Asus will fix this or improve it they always do and always will
[Asus  Eee Pad Transformer Prime] jdbaker82:
So this proves here the prime does infact have a stand alone GPS that is supposed to work regardless of WiFi yet ASUS wants to blow bull**** excuses to its customers? Farewell ASUS see if I ever recommend your brand to my computer clients ever again.

---------- Post added at 03:14 AM ---------- Previous post was at 03:11 AM ----------

I guess you are too young to understand personally I do not care about the GPS this is based on principle alone.
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
Well, assuming everyone has similar results that proves the GPS chip works and that it's supposed to work like every other mobile device. Basically, it's just a weak signal getting to the GPS chip and, when connected to Wi-Fi, you can't really tell because aGPS is hiding it. What's still hard to understand is why after you've locked you seem to be maintaining a decent signal (without Wi-Fi connected) even in places you can't get an initial lock.
[Asus  Eee Pad Transformer Prime] tylermaciaszek:
What principle? There is none I may be young but not stupid
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
The past couple of pages have been pretty constructive. Because of that, the timing of your "get over it" post is a little strange and out of place. No one's bashing - just try to figure out a problem so hopefully it can be reported to Asus and fixed.
[Asus  Eee Pad Transformer Prime] g0t0:
A quick update to let people know, I sent my Prime back yeasterday (tue) to ASUS for no GPS. I'm hoping to get it back by next sat (was told 7 working day turn around). I'll let you know what happens...:)
[Asus  Eee Pad Transformer Prime] jdbaker82:
That a company would knowingly ship out faulty units just because they can to make money and then not acknowledge the issue to its customers or at least let them know they are doing something to resolve it. Instead they are telling tech support reps in India multiple different excuses that couldnt be further from the truth...... now you tell me what principle.
[Asus  Eee Pad Transformer Prime] skeptikal:
While I am a little jealous seeing Barry's Galaxy Tab 10.1 get a lock in airplane mode after a cold boot indoors I feel ok having seen my Prime lock satellites in airplane mode after a cold restart. I just happened to have to be outside. :) Once I do that I can get a lock indoors if need be. That's acceptable to me for now. Thanks Barry for all the help.
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
No problem. This was fun. I'd still like someone who knows the mechanics of GPS better than me to explain why it seems harder to get a lock than it is to maintain it. Is it something with the chip itself, the antennas, interference, the metal casing?
[Asus  Eee Pad Transformer Prime] richB7:
Did a video comparison with the ASUS Prime and Galaxy Nexus getting satellite lock with GPS Essentials. ASUS is slower but indeed works, though indoors the Nexus performs about the same as is does outside where the Prime won't see any. Yes I realize this is a tablet compared to a phone and HC with ICS so this is not a scientific comparison but just a simple one.

http://www.youtube.com/watch?v=V2fp4edWbhc
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
The Prime seems OK if it's connected to Wi-Fi or, if not, had gotten a previous lock. No one (yet) has gotten it to lock in airplane mode without a clear view of the sky. If you're up for it, put both in airplane (flight) mode, cold boot them, and see what the results are. If you're really up for it do it both indoors and outside with a clear view of the sky.
