Samsung with ozi GPS dropping in and out

Just changed to a tablet with GPS (10.1" Samsung 4g 2014) for ozi from the laptop and had a good long weekend in the Big Desert Vic but found the GPS would constantly drop in and out.

Even the Google maps would do the same.

On the way home back to Adelaide it wasn't as bad, I tried different settings but nothing made a difference in the desert.

Any ideas?

Thanks

Christian

Lets try and narrow this down.

The GPS satellite system has been working OK, and WW3 hasn't been declared (yet).

Google Maps and OziExplorer are both fairly reliable bits of software.

From your photo we can see that 12V power is getting through to tablet and radio.

That leaves the hardware. I have a Samsung TV which works quite well (albeit with crap pre-installed software). It locks up and has to be turned off if I broadcast on the HF band though. Perhaps your UHF is interfering with the tablet.

Its probably not designed to be a mission critical navigation solution.

ShamScum - they can copy the look but they can't copy the quality ;-)

Thanks Bob, didn't try the UHF off and we also had a HF which was on.

Will try next time.

Cheers

I know absolutely nothing about tablets but from what has been said and from the photo showing that it is a little way back from the windscreen, I would be suspicious of the device or circuitry getting the position from the GPS birds.

Forget Ozi for the moment. It is a stable bit of software. I have one of those Interior Design pocket thingumys that sits on the dash. It had shifted over the GPS antenna and "shaded" the GPS antenna from the satellites. The program would lose GPS location (an audio warning) and then it would come back again. I moved the pocket thingumy back to the bcenter away from the antenna and all good.

How does it get it's position?

I use a 2012 Samsung note 10.1 tablet with Oziexplorer, but I disable the internal GPS and use a Holux M1000C Bluetooth receiver and data logger, which sits at the front of the dash on Velcro. Never had an issue with losing the Sats and has the added advantage of recording your track and being able to download and view on Google Maps along with lots of data showing speed etc.

As others have said it is probably the inbuilt GPS losing signal, usually worst when heading in a southerly quadrant as the GPS sat are in an equatorial orbit and the vehicle shades the signal.
Another easy solution is to use a reradiating gps antenna. Just has an external antenna and then reradiates the signal inside the vehicle for any GPS devices to pick up the signal.
We've had one for about five years now which works well.
Bought it on ebay for about $40.

You must be thinking of some other satellites. The GPS sats are in polar orbit.

You sure? I always had a problems heading south and when in the northern hemisphere we sometimes lost signal heading north.
Had a look on the net and they go every which way so we're both wrong ;-)))

The GPS satellites are not quite pole to pole they run at 55degrees to the equator.More info here That said, I get better reception when not facing south ???

I do use an APP on my tablet (android) called GPS Essentials that show the locations of the satellites available in the sky at that time, the majority seems to be north of my position up here in FNQ?

There was a discussion a little while back with regards to tablets with GPS and tablets with AGPS, my Sony Xperia Z tablet has a GPS and no SIM/3G telephony and works very well in all location except in doors.
A tablet with AGPS can use the WiFi or 3G network to speed up obtaining a location, this is fantastic if you travel in regions with 3G reception and quicker than a GPS unit. Some AGPS chips 'may' not work as well as a satellite only GPS in areas where a "pre-fix" by 3G is not available.

Turn off wifi or mobile data to check how good your unit is when at home and outside.

Hi Christian,

I also have a Galaxy Note 10.1 2014 running Ozi but I haven't had it set up in the car to play with it as yet :-(

I notice what appears to be a RAM mount cradle that fits your tablet quite snugly. Do you happen to recall the part number for it? I couldn't seem to track one down when I bought mine recently so I went for a multi fit RAM-HOL-TAB-LGU. It's OK but I'm not sure that it's up for the corrugations that the CAR will throw at it.

Thanks for all your feedback, I spoke to Electric Bug today and this is an issue with ipads and tablets so will purchase a Garmin Bluetooth GPS to fix the issue.

The Ram mount Vince is excellent and suctions to the window and claims to hold the weight of you hanging off it and it does certainly hold.

I looked at the floor mount but prefer looking at the same line as the driving and I look at the maps a lot.

On the invoice there is no part No. only Ram mount thin ipad case $39 and the twin suction cup window mount $35 and the ball fittings all up $115.

Will let you know on the next trip.

Thanks again

Christian

Oh, and I did trim the top two sides of the Ram mount down a bit and re-glue as it was almost designed for a 12" you can just see the cut and shut marks at the top.

Thanks Christian,

Hadn't thought about the cut & shut route. I reckon that I might give it a crack.

Christian, I run a toshie 7" android in the car mounted in a similar position. The satellite "fix" does seem to have improved since I changed from my original mount. Not that I was having as much trouble as you though, I just wanted to alter the position for the usb charger cable. It meant the tablet is now mounted with the opposite side clear of the dashboard, I suspect the gps antenna may be situated on what was the lower edge of the tablet and of course it would now be on the higher side.
Just a thought have you tried turning the tablet around 180 degrees ?
Cheers
Peter

Thanks Peter, yes tried it out of the case and cradle and standing still outside and it would lock onto 15+ satellites and then suddenly none.

Thanks

Hi Christian,

A long shot but could it be that you are only using the wi-fi and mobile network to get a location fix?



I have a 10.1 and never have had any problems with getting sats.

Thanks Alan, no we had it on GPS only as there was no mobile reception out there so needed the GPS.

Thank you

I also have the same and also have problems getting sat lock, I got the deal where you use the garmin navigator software for free but not a good app.
I might try the blue tooth gps soon but I shouldn't have to.

Does ozi work well on the samsung, I was told it's not as good as the pic version

Thanks 749, Ozi on the Samsung is great much easier to use than the pc version as we have had for years with the laptop mounted in the car.

Just using ozi's features is so much easier than moving the courser and one clip to check for other maps in your location.

Cheers

Hi Christian

Maybe a hardware problem with the tablet (discounting Google maps as they often use an internet connection and I'd expect them to have difficulty out of the city).

I've just been through the Gibson Desert up to Kintore, over to Alice and back to Perth via the Great Central Road using a Samung Tab3 8" running Ozi Explorer for Android without a single glitch. Similar mounting to yours and sometimes even had my hat thrown over the tablet for some shade....still 100% reliable.

Only thing I noted was charging can sometimes be an issue during low voltage (vehicle off). I used a 2 amp cigarette lighter / USB adapter for power and a couple of times, when the car was not running, I notice battery charging for my phone and / or the tablet would sometimes stop. Charging resumed as soon as I started the car.

Good luck with resolving the issue.
Chris

Could be Chris, I will contact Samsung but unlikely they will do anything but it's a bit annoying as I could of just purchased the non 4g model and buy the Bluetooth gps which I will have to do anyway.

Thanks

Hi Christian

My tablet is non 3G/4G (WiFi / Bluetooth only) but still has an inbuilt GPS. he inbuilt GPS seems to work well for me.
