GPSlim Holux 236 couldn't find satellite in France - 8125, K-JAM, P4300, MDA Vario Accessories

Last summer when trying to use my GPSlim in southern Montpellier, France it never could lock on the satellites. I am going back this summer and would like to have GPS to use. Any suggestions on why it didn't work? Works fine here in the US.

Notoriously bad after changing locations
In my experience and the threads I used to read the GPSlim 236 is notoriously bad at finding satellites after changing geographic locations. I usually remove the battery for a few seconds, reinstall it and then it works.

Problems with HOLUX GPSlim 236

Hello everyone!
I recently bought a HOLUX GPSlim 236 mouse to ue it with a navigation software on my beloved MDA III!
My decision for the HOLUX was actually based on various posts in this forum, where that GPS mouse has been praised as a very good, fast and responsive device!
Unfortunately, the results I have so far achieved, are almost pathetic!
When turning the HOLUX on after it has been turned off for the night, it takes the GPS pretty long to get a fix (which is usually signaled by a blinking light on the device). Sometimes it really takes forever! For example, today I turned it on when leaving the appartment. I went down the three stories to the street, walked on the street for 2 minutes, waited for the tramway to arriv for 1 minute, sat in the tramway near a window for 15 minutes, walked to the office in 5 minutes.... finally, shortly before arriving at the office, the HOLUX got a signal and could show me my position!
But even then, the position of me walking down the street was not even close to precise. Exact position and walking direction are almost always wrong when on foot!!
In a car, when finally getting a fix on the satellites, the positioning is sometimes better..... but only sometimes!
Long story told short: The results of positioning are poor! I wonder, where the problem might be!
DAMAGED DEVICE?
FAKE IMITATION? (how can i check what chipset is really woking in that thing?)
IS IT THE DEFAULT OF THE MDA3 and its poor Bluetooth abilities?
WHAT ARE YOUR EXPERIENCES WITH THE HOLUX 236? SPEED? POSITIONING?
dont know what to do....
any help is very much appreciated!
regards,
krz
Did you try Holux Support site? I have the same model and had some issues, and they helped me resolve them.
Here is their website: http://www.buygpsnow.com/support/show.asp
I've been using the GPSlim quite satisfactorily. It does sometimes take long to acquire a fix though, and I'm not sure of all the reasons for that. (Other than that obviously Bluetooth and the BA have nothing to do with it.)
GPS devices generally take longer for acquisition when they are switched on in a different place from where they were last used. They store a so-called "almanac" which helps them find a quick fix because they already know most of the position data. (This is called a warm start.) If switched on away from the old position, they have to re-acquire to almanac, which takes longer. ("Cold start.")
As for the lack of accuracy, unless your GPSlim is damaged, I'd tend to blame that more on the software. The software knows about streets, etc. and will try to put you on one of them if the data is not close enough. With e.g. Tomtom 6 on the BA this usually works very well. If your software doesn't do this sort of "magnetic snap" to a street well then your position will not be so accurate. It could also be that the "snap-to", which IMHO requires some measure of anticipation about which direction and speed you are moving, works better when driving than when walking.
I can't really complain about the Bluetooth performance with my BA & GPSlim ... however for navigation on foot I tried to put the GPSlim (as it's so small) into the zip hood collar of my coat but found that the bluetooth connection doesn't work with the Holux on my back, behind my head, but does work if I slide the GPS in to the tip of the collar -- but it works best if I'm holding the BA in my hand the same side where the GPS is in the collar tip ... so the quality of the Bluetooth connection does seem very delicate!

[Q] [SGSII] - poor GPS accuracy? Post your results!

Hi Guys,
I'm making an article about SGS II and I've found out, that there is again issue with the accuracy of GPS position (like Galaxy S had).
First clue was the article on GSM arena:
The LG Optimus 2X got hold of between 7 and 9 satellites and used 7 of them most of the time. The reported accuracy settled at 5m and mostly stayed there with the occasional jump to 10m.
The HTC Sensation spotted 9 satellites and used them all (more satellites potentially lead to a better lock). Accuracy started at around 8m but quickly reached 3-4m and held steady. Note that this is reported accuracy, but actual accuracy should be proportional to these readings.
The Samsung Galaxy S II performed worst in this test, using all of the 6 satellites that it managed to detect. Reported accuracy went between 18m and 20m but varied quite a bit during the test (even though the phone was completely stationary).
I've used the same application and compare it with Xperia Arc. We were standing outside on one place. Finally I got about 30-40 feet on Galaxy SII (still changing). Xperia Arc started at 10 feet and quickly settled down to stable 3-4.
Does anyone has SGS II and some other Android phone to compare it? I'm curious, if this is problem in general or just few bad pieces on market.
Thanks for help...
I tried GPS + Wireless Netwok assist, GPS test says 10 sats in view my location is not even accurate to 1Km
My GPS is great, never had an issue with accuracy. although I had to find out that my gps.conf says "north-america" as the default nntp pool instead of "europe" on a german (DBT) SGS2 is really strange, still my phone get's a cold lock with 10-20 seconds (10s standing still, 20s while driving).
Mine is very fast and precise - I would say its 1 minute to locate me when im outside with wifi switched on.
Original firmware GPS test was May 2011 .
Lock cold boot never used GPS before
no Wifi No network no AGPS .
GPS only
4 min 8 sats locked on . Accuracy 13 metres ..
Subsequent lock on faster as expected and 5/10 m accuracy .
No further tests as it just works .

I use Navigon three times a week and i never got problems with my sgs2. The gps signal is like my iphone 4, i only navigate with the voice!
Real world driving accuracy : 20-30 meters (can go down to 5-10m, but only in truly wide, open areas)
Lock Speed : few minutes
Barely usable as a navigator, at least in urban areas. The above are under KE7 and KF3. Really disappointed by the GPS performance on mine.
my gps works fine often i use wifi
Changed my NTP server to asia, I can now even get a lock inside the house, sweet!
Guys, thanks for replies.
Anyway I think this issue won't appear that much on driving navigation, as this software "sticks" to the nearest road and use the speed to make the position as accurate as possible.
Bigger problem I see in terrain while searching for way home, or while playing with Geocaching.
Only positive thing is that from digging in ground at area 20-40 feet wide you will surely obtain big muscles
did you guys already look thru this thread? all the good info is in there too.

upps, I was trying to find simillar topic. Than maybe I would like to ask somebody to lock and delete this one.
Thanks...

Inaccurate Current Location in Maps?

I am currently in Hong Kong, using Google Maps on my phone. On my old Blackberries, the GPS is accurate, the arrow sits right on the building I live in.
However, with the S2, it is either off by an entire block, or takes 2-3 tries, and finally narrows it down to within 200 feet of me. I am sitting right next to the window with GPS turned on, and the arrow is sitting on a building across the street from me.
Anyone else have this problem? Is there a fix? Maps is sort of useless to me when I need it the most.
Thanks!
Always been accurate for me outdoors of course less reliable indoors as it cannot see the sky .
Possibly try the latest KG6 modem .
Faster fix from the market and GPS Status may help .
jje
Thank you for the input!
I tried faster fix, the arrow finally landed right on my building, but a couple seconds later, it jumped to a located two blocks away. The other times, the arrow was at least 200+ feet away. I will flash 2.3.4 sometime soon, even though I've rooted my phone, flash custom kernel and all, I am still waiting for that update firmware to 2.3.4 to show up in Kies...
From my remote village, the Google Latitude location is never accurate. It jumps around as you described (I'm still using 2.33 firmware).
However, if I turn on WIFI (even though there's no wifi around...or home wifi is turned off), it becomes more accurate and less jumpy.
When I'm riding around my tuktuk, Latitude is very accurate (not jumpy) if I turn on both WIFI and GPS.

External GPS & Prime

Hello prime users.
I am currently on my second Prime. About the only problem I have discovered with it is poor GPS. That being said, GPS is one of the main reasons behind my purchase in the first place. Realistically, I never expected a built-in GPS to meet my desires anyway. I want to use it in aircraft. OK, stop right now & don't attempt to lecture me on the rules. I quite possibly know them better than you.
All I am interested is "Situation Awareness". The aircraft I fly all have IFR certified GPS installed. The FAA (or some other government alphabet group) has not seen fit to allow terrain features on most IFR aircraft GPS units. Where I live and fly we have mountains--Big Mountains.
The fuselage of most aircraft restricts the incoming GPS signals to any device lying on the seats or in the pilots lap. Therefore, an external GPS receiver is almost mandatory. The solution that I have found is made by the company "DUAL". It is the model XGPS150 or XGPS150A, with the A being the currently produced model. I can verify that it connects via Bluetooth to the Prime almost instantly, tracks flawlessly at up to 200 Knots groundspeed (I have not attempted to use it in one of our faster aircraft, YET), and it just plain works. It is advertised to have 8 hours of battery life and comes with a nonslip dash pad, and arm/backpack band and a charger that works between 12 & 30 Volts DC. The cost is $100 US, and I did not find it discounted anywhere, including EBay.
I also used this GPS-Prime combo in my vehicle enroute to work yesterday. At highway speeds, and when displaying the Google Satellite view, it appeared to be within 150-200 feet of my actual position. In residential areas at 25-40 MPH, it appeared to be less than 50 feet behind my actual position.
I am not affiliated with Dual other than being a satisfied customer.
Best to you all.
Jerry
Did it work out of the box, or did you have to set up a "mock provider"?
I've got the Dual (not the A). I'm shocked by the bad accuracy....Right now, in my bedroom, my DUAL + Bluetooth GPS app shows the accuracy @4.5 meters
I'll have to wait till tomorrow to test it further.
I've gotten better accuracy with the "10cent+beer solution, with just a 4" hanger wire taped to the top.....That technique usually give me 45-72 ft.

Bob- You do realize that 4.5 meters is approximately 15 feet; which would be 1/3 the minimum you got with the beer can chicanery. Indoors (where GPS has very little signal), I'd say that +/- 15 feet isn't so bad, actually pretty darn good.
Pretty much "out of the box". I followed the instructions that came with the unit--some mods necessary, but pretty obvious.
I just turned the units on and the GPS TEST app shows between 7.6 & 8.3 feet accuracy.
I'm located at 61N & 150W.

Wow....it's amazing how one word changes the total context....
"I've gotten better accuracy with" should have read I've gotten better accuracy THAN with...
I hope that they are plannng on developing their test tool for the Android. It's a nice tool that shows battery left, and a bunch of GPS data....but unfortunatly, it's only for the IPAD (unless you know something that I don't).
Don't you need data to do this?

I see the change by adding the word . I still don't see how 4.5 meters from the Dual unit is 'shocking' bad accuracy.
I've got both the qstarz bt818xt and the gsat bt368i. I use bluetooth provider (free) with mock locations and both of them give me three foot accuracy (1 meter) while driving I use sygic and it is accurate to 10-20 feet at 60 mph. I will be sending one back but can't decide which, smaller vs longer battery and more channels on mtek vs sirfIII

Sorry again, I meant your statement of "it appeared to be within 150-200 feet of my actual position"

You only need data if you're using an online map (e.g. Map Quest, Google Maps).
There are plenty of offline maps available, some of them Open Source.

GPS

All, what is gps like on the s3? Doors it get a strong lock quickly and stay locked? How does it compare to the s2? Really interested in this add I use navigation a lot
Sent via TCP/IP
I've not used the GPS at all when out and about, however I just turned it on in google maps while sitting in my bedroom; the phone got a lock to 10 metres within 6 seconds.
I was impressed!
Used mine a few times now when driving, it locked very fast and had no issues.
The combinaion of GPE/GLONASS is awsam. it works inside the building, locks for seconds, find at least 13-17 sattelites inside... perfect.
Sent from my GT-I9300 using xda premium
Same here GPS fix is almost instantaneous, accuracy very good. Now if we get TomTom soon I will be very happy, Google nav just doesn't do it for me.
when I think how poor my SGS 1 was for GPS

Thats great news, using sgs1 now and gps is driving me nuts!

Yes, the GPS fixes very fast, like some of our friends mentioned above, partly because this GPS system is in hybrid with the former Russian Glonass system, hence catches more satellites. However, I am disappointed that the accuracy is not different than my older traditional GPS system on older phones. The best accuracy that I got is 5 meters under clear sky conditions so far
