question about GPS signal power??? - Hero, G2 Touch General

hi everyone...
I have a Sprint hero on MoDaco 1.3.
It is working fine...
I have copilot and google maps.
Both were fine till it got stormy here.. Very Cloudy.
For 2 days of cloudy skys.
My GPS has gone crazy!!!! While I am driving in my car it shows that I am jumping all over the city. Then it had me on the other side of the state of Texas! and it was stable there!!! Today it had me hundreds of miles off the coast of California!!!
This is in both copilot and google maps.
then the sky got brighter.. but still cloudy later in the day.
My GPS was now back to accurate!!
SO... is our GPS receiver that weak?
ON very bad rainy/cloudy days, we will be able to count on our GPS? I have a MIO GPS device and I can count on it in any weather condition.
Has anyone else experience this??

Strange
I'm no expert but I certainly think the weather influences the signal, GPS devices like your Mio use more power for it's receiver ofcourse, thus have a quicker fix and a stronger signal I imagine. The only thing I find strange is it jumping all around town. On a cloudy on my Touch Diamond it took ages before I had a fix but if the weather got to extreme it just lost signal that's all.
I can imagine that if there were thunderstorms the static could mess up your signal as well.

GPS Accuracy

I bought the HTC Touch HD a few weeks ago and noticed that the accuracy is not just bad, but atrocious. It can't even locate me within a 300 meter radius. Is that normal? Does anyone else have this problem? I am using the latest Google Maps.
Thanks in advanced.
I would try a proper GPS program and see if it is the same, if so your HD is faulty.
No problem here. .Maybe silly question, but did you click on "Use GPS"?

Are you sure you have a satalite lock? Google maps also determines position from cell towers and gives an estimate to your location within approx 500M. Once gps is activated and satlites have been aquired, a more accurate position is displayed (and i get a blue triange above the location - i guess to indicate actual position).
The little blue trianlge shows the direction you're moving - so the GPS is pretty accurate! Sometimes it doesn't get a lock for a while (it'll say at the top-right when it has active satellites) - if not, then it just uses that cell tower triangulation thing which gets it within about 500m as mentioned above.

Ya, it is on.
It can get working when I'm on the move, but as soon as I am still, it screws up. For instance, I can be driving to work and it works fine as far as telling me where I am at the moment. As soon as I close it and reopen it at work, it tells me I am somewhere 300-500 meters from work.
I guess I don't understand how it can work so well on the move, but as soon as I need an accurate reading, it is way off. Does this happen to anyone else?

Once it's closed it loses the "Use GPS" setting and you have to turn that back on and wait for the Satellites to be located all over again.
Well i think there is a gps delay issue with the latest HTC phones as blackstone, Raphael and diamond and i believe there is a little on the x1. Well there will is always ways to tweak settings in the registry i guess. well you'll probably find something here at xda...
Ok, I see what you are saying...sa we speak, I am trying to get the location of where I am at on my phone. The status has been on "Seeking GPS satellites (0)" for about 3 minutes now. It just relocated my location nowhere near me.
Ok, I just got a message telling me that my "GPS receiver is having trouble tracking GPS satellites." It's a very clear night in southern California, no clouds, no trees, etc...If it is because I can't get a satellite, is there a way to configure it?
Can it be because I am inside my house? If so, that is absurd!

Well i suggest you to go out and test it.. well also i suggest you to always keep your quick gps application updated so you'll get a quick fix locked to sattelites.. my Raphael locks on around 20-30 seconds and sometimes even less....
no problem here!
i've tested head to head with my old Asus P535 SirfIII (wich is pretty good as gps) on a 300km trip and they react in the same way.
no lag, no errors.
i use iGO8!
Well i found this on youtube: omnia vs HD in gps...
i am aware of that greek clip
what can i say? they have their experience, i have mine.
from my experience i say the gps of hd is good enough, as long as i don't make maps and i don't need precision on cm level
GPS works great on HD. Tested with IGO8 and latest TomTom, as well as Google Maps - all have accuracy within 5m range, wich is more then enough for normal navigation use.
I also tested my HD along side with Garmin car navigation unit - they were literary synchronized to the very second, even the voice instructions came at the same time, it was actually very funny
If you're having problems, I suggest you look up here on the forum for HTC GPS tool.
Well just to say, I agree with you guys eventhough i have a Raphael.. well i guess the gps chipset are the same.. (correct me if im wrong though) .. well many people in the Raphael community is talking about 50 - 100 yards lag but i only experience 5m, the most ive experienced was 10m but that was just once..
GPS doesn't work inside. Not just on the Touch HD but on any GPS device.
At the most, my lag is a car's length. I think my Trinity was slightly more accurated but not by much.
As far as getting a lock from inside, I can occaisionally get a lock if I am sat by my West facing window, but otherwise not a chance!
Ok, I got it working! I guess it just takes a couple minutes without touching any keys to acquire the satellites.
So in conclusion, to impatient people like me, don't touch any keys for a good minute or two. Thanks, guys!

Mine does. Can take about a minute/minute and a half to lock to the satalites, usually finds about 9 of them, and from google maps when zoomed in to max you can see roughly where abouts in the house the handset is.
The cell tower lock is useless. I'm in the north west of england. The cell lock feature keeps telling me I'm in Russia!!
like all gps i have used, sometimes getting a fix is hard work, regardless of apparent sky conditions.... i guess thats what happens when technology (the gps sats) are made by the lowest bidder
if you have a "your postion within 300-500m" message displayed, then that is using the cell mast to get your position, you never see this message when using GPS
some progs and some roms prefer to have the gps ports mapped, i do it manually for all my gps progs using com4 and bit rate of 9600k... seems to offer best situation
afaik, no civilian GPS can assure an accuracy of greater then 15m, although some units some of the time seem to be more precise
i dont see lag, i see the limitations of GPS (outside of military application... but then again, we've seen how accurate smart bombs are not!!)

HD2 GPS perfomance

Hi All,
At the moment i own a TP (a.k.a HTC Raphael), but i'm thinking about buying a new phone and the HD2 is one of the candidates. Before buying i would like to know if the GPS performance of the HD2 is up to scratch?
For some unknown reason reviews never (...hardly) include GPS tests.....WHY!!!??
The GPS performance of the TP even with the official HTC patches is still worthless. Waiting for a fix could take an hour (i'm NOT exaggerating).

i know what you are talking about, i had an TP before my HD2 too, and i have to say there is world of difference between them. with my tp i had to wait about 15 mins. with hd2 about 10 seconds.. even inside buildings i get a fix! with my tp i wouldnt even hoped for that.
so yeah its a LOT better
The HD2 is in a different GPS league from the TP, Diamond, etc. They were a disaster.
IOW it's much better IMO.
Works pretty good. I just enable QuickGPS when I flash a ROM and I never have any issues (never tried using GPS without that!)
I've an everage GPS fix in ~15sec.... It's brilliant! even from cold start!
Sometimes you get GPS even in very light buildings
GPS is awesome, simply awesome... outside get a fix in a few seconds with full sat coverage (all the columns show a satellite) inside it takes a few seconds longer and again full columns... there is barely any lag on the journy (icon vs real travel)...
GPS fix in 30 secs in Street Navi, 15 secs in Aviation software ...... great!
Also, 10-15 seconds, outside even less...
What I find amazing: Even in my living room, sitting about 1,5m away from the window, I get fix to 7-10 satellites within 20 seconds...
(Always with fresh QuickGPS data)
when i had a diamond i had no issues at all, the hd2 is a lot faster
I have never used GPS on a PDA before but have a dedicated (new) TomTom GPS unit and when I decided to try my HD2 I mounted them both in the car and ran tests.
Within 5 minutes my mind was made up. The TomTom was outperformed in all areas. The route recalculation is much much MUCH faster than the TomTom and the same applies for the aquisition of the GPS signal. Combine this with an awesome screen and it is perfect. I play music throught the headphone socket to my car stereo and run GPS at the same time. When a call comes in the music mutes and resumes when I hang up. The GPS unit runs in the background without any issue. The TomTom GPS unit is now in the cupboard collecting dust.
I have never used quick GPS as I have never had a need.
I agree, HD2 GPS works like a charm.
QuickGPS - what for!?
After reading the feedback in this thread, I suddenly remembered the QuickGPS. Last time I used it was two months ago, because... it was there to be used! Without QuickGPS I get a fix in my HD2 in around 5 seconds! I am not joking! Never felt the need to go for QuickGPS. BTW, went just now to Options and ticked "Download QuickGPS automatically". Why not!? I have Copilot 8 and love it. Just missing the QWERTY keyboard. Otherwise, there's no better combination in the world when it comes to portable phone-music-GPS-video-Internet-camera-etc, etc.
Wow! Thnx u guys for the feedback!
I can live with getting a fix within 30 sec's on a cold start (coming from an avrg. 15 mins for a fix). The HD2 seems to be the PDA/Phone that i have been waiting for since the dawn of Pocket PC 2002 .
HD2 here i come!
I've found the HD2 to actually get a GPS signal even inside my dad's car. no other gps device can get a signal through the windscreen. It's weak on the HD2, but there!!!
A bluetooth GPS stick cannot even penetrate it.
HD2 GPS is a joke!
I do not mind much if the GPS locks indoor, though HD2 does it very easily indeed (and fast). I find really bad is the very poor precision of HD2 GPS - it constantly gives a 20-40 meters error in all directions (no matter in the city or in open field, no matter how many sats are found, even 10). My old Samsung i780 has an error within 2 meters. Just record your path (on feet) with e.g. RunGPS or NaviComputer and you will see the the ugly zigzag line instead of a smooth one which I used to have with i780. Of course if you are not lucky to have HD2 with much better GPS than my..
(It is almost OK with TomTom car navigation, though, with occasional map rotating and recalculating the route).
GPS is very fast and precise here, definitely the best GPS signal out of all the WM phones I've owned
My GPS with iGO conects in about 10sec and its very precision. Corect in area of 3-4 meters

This is interesting, maybe your old Tmous radio (..50..) is doing a miracle. i have 2.09.51.03 radio, the previos 2.07.51 had the same bad GPS precision.
However, how do you know that it is precise? If I simply looking at a Google map standing still, I see pretty precise spot which my GPS gives, but once I begin to move, the position begis to jump 20-40 meters to all directions..
HD2's GPS really rocks! My old N95 took about 15 mins to fix.
yep fast here as well about 10 sec for a fix cold.

[Q] GPS

Hey everyone. Last week I got the MT4G. I noticed that my GPS is acting funny. I am able to get a lock on to satellites on Google Map but it has the blue circle around my location and says approximately 20 meters (on average tho I can get 10m to 60m). I am using GPS Test (by chartcross limited) from the app store which has a section that shows the GPS's accuracy in feet. Both the GPS Test and Google Maps show the best my MT4G's gps is up to 20 meter(google)/feet(gps test). This is with 6-9 satellites. I live in NYC and my HTC TyTN II worked fine (which just got stolen after many years). It was able to locate me without any blue circle or approximation.
Can someone confirm that the GPS get around 20 feet/meter on Google Map. Maybe someone can download GPS Test and share there results. I need to know if the GPS is defected so I can replace the phone before the return period ends.
PS: I originally rooted it. Then used CM7 for a day. Tried to restore back to stock using clockwork mod 3 but that failed multiple times (i had 2 backups both failed) so I restored it using Football's Glacier_TMOUS (ROM). So I'm back to stock, not rooted (as of now). -This GPS issue exisited when I got the phone, after root, after CM7 and still exist. I know others have reported a similar issue, but I dont know what to do. (i am lucky to have the good screen, and really dont want to have to return it and gamble for a good gps and a good screen).
Many Thanks in Advance.
as long as the ring is small your fine. GPS isnt exactly accurate down to the last foot or inches. honestly i think anything within the 5-25ft range is pretty normal.

[Q] GPS problems

My GPS drives me nuts ... the signal is weak even outdoors on a sunny day. GPS Test shows maximum levels of around 25 on the street and even less on the balcony.
From the reports and Youtube videos I saw, the TF should do better than this, instead of constantly loosing GPS signal, shouldn't it?
Btw, I tried all available settings.
Might my TF be faulty?
PS: Is it normal, that the TF has less GPS problems in the late evening?
I haven't been all that happy with the GPS performance either. I haven't managed to get a lock when starting from a cold start at all, it sits there finding no more than 3 or 4 satellites at low levels, even after 20 minutes. By cold start I mean the satellite data wasn't updated in a long time, and therefore the TF is searching on his own for satellites.
When I was connected with Wifi and launched different GPS apps, I was able to get a lock in about a minute or so, which is more normal.
Unless you have the ability to tether to your phone, or or are connected to a wireless router, I think it's absolutely necessary to keep your TF's satellite list up to date manually, or before you leave and know you will be using your TF as GPS device.
I don't think late evening has to do with anything, but the weather can definately interfere (think fog, rain, lot's of clouds).

Currently in the late evening that's what happens with my TF ... I even get a low level around 20 sitting on the sofa 2 meters away from the window.
This afternoon I even had problems in front of the house with a clear sky, where I also had WiFi connection. Yesterday the same experience.
Why is it better in the evening in my case? Strange.
But maybe I have an explanation: On the roof of the house on the opposite side of the street is a large cell phone antenna. Might this cause my problems? Maybe because there's less traffic in the evening?
Problem solved !
I downloaded MapDroid and tested the GPS in the car ... voila ... worked like a charm.
I drove 20km with the TF switched off, stopped, loaded MapDroid, waited until my position appeared on the map, which only took 1-2 minutes and drove back, checking the map at every traffic light.
So it seems, this cell phone antenna on the neighbour house caused my GPS problems at home.
Nice one. I don't think I've actually noticed one of those towers or know what they look like.
ehow.com 's suggestion on how to acquire a GPS signal:
http://www.ehow.com/how_7315691_acquire-gps-signal.html
"2. Get away from anything emitting electronic signals. Radio towers, cell phone towers, and other electronic signals can cause interference with GPS signals, leaving your receiver with little to no reception."

Just google images for "cell phone towers" and you'll find tons of examples. The one on the house is one (!) of this flat long things. The huge masts with lots of antennas you see in most pics are usually not found in residential areas ... at least here in Germany.
well..a trade-off for getting a strong cell phone signal!

Gps on OP5

Hello,
I want to buy a new smarthone but I hesitate between the s7 edge and the OP5
I see on the test that the op5 is one of the best smartphone but i'm afraid about the gps localization.
Is the gps work well ?
Is waze work well or that search the gps localization all the time?
Sorry for my English :angel:
Using the Waze app daily on my OP5, no problems at all. Accuracy is perfect, locked within few seconds. This phone flies in every possible aspect (compared to my previous LG G3).
Same with mine. I'm in the eastern USA use Google maps 2 or 3 times a week, I've never had lock issues and never experienced GPS drift. Best GPS performance I've had on any smartphone to date.
I'd say you have nothing to worry about
GPS works very well when i use the Google Maps.. fast lock and accurate..
it also gets locked with many satellites (from 5 different GPS-like systems) when i run GPS test app..
I can say I've e had issues with reception while running both maps and Waze and I lay the phone on the passenger seat. It looses gps signal.
Using Android Auto everyday with Google Maps displayed and it's been working like a charm for me. If it doesn't lock in two seconds, it won't take long before it does anyway and the performance when driving or even riding my bike with Google Fit has been excellent.
Although, I did have one time where the GPS was not working and I guess it was using antenna triangulation until I restarted Google Maps. But that's still better than my previous Note 3 and close to the precision of my Garmin.
Last time I checked with GPS Test, I had a 3m precision most of the time with many satellites in use. Almost all of them were yellow but performance in the end was still awesome. The only thing that is going weird for me is the compass as if my phone is not mostly standing up or laying flat compared to the ground, it gives me a weird reading some times but I don't hold my phone between those two positions when walking and when it's docked in my car, it's in the standing up position so the compass works well for me in the end.
