I have not connected a computer to it yet to download. To my great frustration, it is Windoze only and there is no Mac software interface. A major fault right there!!

When you say the above, do you mean that you need Locosys's proprietary software to download the data off the unit ? (which is MeSsy Windows software ?)

Thanks for the info

I plan to pick up Surf Sail Australia's unit tomorrow, if I'm feeling adventurous enough I'll try installing the associated firmware in Ubuntu.

quick start guide and software are here.
~~http://www.locosystech.com/MAP/GW-52_Utility_150427.zip~~

Anything you want me to check Andrew?

Thanks Mike. Hmm, is that an old link you saved? I can't find anything to do with the GX-52 on their website now except a banner with some pictures.

It would be good if you could do a bit of geostationary logging with side by side GT-31 and GX-52. The more the better.

Any sailing side by side testing is useful as well. Make note of antenna orientation if possible. I am interested to know if it is more sensitive to this than the GT-31, but I think the larger antenna in the GX-52 will be comparable in sensitivity to the GT-31, and hopefully better.

Andrew Mark only referred to a GW52, not a GX52. Looks like we may have some light wind on Sunday so keep fingers crossed. I'll do a battery and geostationary test with both units side by side.

Reading the quick start guide it doesn't look as if we have a scrolling "history max", but it is available if you can work the touch screen on the water. I'll be very interested to see just what it does.

Daff, any idea of the water proof rating yet I see the plug for the USB could leak but is the rest water tight maybe wear it without a case & test it for us with yours in time.

Got info on latest GW-52 can reach IPX7 level as GT-31.

For protecting unit and extend its life, we strongly recommend you to use a waterproof bag/housing(IPX8 level) when using your unit. Again, IPX7 is tested in the still water for 30minutes at a depth of 1 meter. But it still won’t withstand the use of in extreme sports, like windsurfing.

Sailquik: With your GX/GW52's sensitivity test, a larger antenna (aperture) won't normally increase it's gain (although there are exceptions). When I get my unit (pending OS compatibility and UTC display), I'll estimate it's directivity if you are interested ?. OR you could determine this by analysing the signal strength data supplied in the NMEA0183 sentences (the GT31 logged this data, so I assume the GW can as well) and then compare the signal strengths against different orientations of the device. My bet is that's it's isotropic.

decrepit: Thanks for the info. I'm waiting to see how you download data onto your Ubuntu OS computer. Keep up the good work

Berowne, Picked my test unit up today from Mark at Surf sail Australia, he says they haven't given any indication of pricing yet.

Sausage, there's no card slot, it's internal memory only, so you have to be able to communicate with the unit.
One of the first things I plan to check, is how long it records for in 1hz and 5hz modes.

JN1, I've been thinking about it and I'm not very positive, even if the software will run under wine, Ubuntu still has to mount the thing, I can't see a windows driver being any help there.

I'll do all the other tests before I try this, just in case I brick it in the process.
Unit is now charging (needs 2 hours apparently) and I've printed out the instruction manual.

Looking at the usb cover, I wouldn't trust the unit in water. there doesn't seem to be any pressure between the soft plastic seal and the unit body. Maybe a small piece of duct tape over the seal would do the trick, as long as water pressure didn't tear it off. But that's a messy solution, the body would get sticky very quickly, and the use of solvents could make the display go cloudy.
Just have to see how operable it is in a paqua.

Any more questions/tests?

When you get it charged up, plug it in and see if it detects as a USB mass storage device. If you can't determine this, could you PM me the last 30 lines of your /var/log/messages log file (ie: tail -n 30 /var/log/messages) so I can have a look.

To make a GPS properly waterproof it seems that we need a device with Bluetooth for data and wireless induction pad for charging.

No the only way. The old Garmin Foretrex 201 has contacts and a cradle for connection, but that still was not waterproof enough. The problem was the screen area.

I've had the GW and GT on the balcony all day, doing a static test. The GW's battery is now flat so I'll load the software into the windows laptop and see how long it recorded for. Back a bit later.

Sorry Craig, I was sure I had logging set to 5hz, but the unit's empty and the utility says logging is off. All I know at the moment is it made 6hrs, but didn't make 11hrs.
I'll have another go tomorrow.

Installed the utility on ubuntu under wine, and it seems to work OK, but the driver doesn't want to install and the utility just come up with com port error when I try to connect to the device. No more than expected really.

Hi Mike. I also tried to test the GW-52 with a GT-31 today as well. Put them on my dash as I drove into to the Gun Club, left them on the dash all day and drove home again.

Fired up my old XP happy and found.... no file!! What the......!!!!

I had actually twigged that I had 'smart' logging activated which apparently means 1hz logging under genie speed and 5 hz over it. Also has 2 kt min speed so whacked my forehead and realised the stationary test was not going to work. It should have logged the drives though so I will have to have another look tomorrow. I might even get a sailing test!

Bugger!
smart logging sounded like a good idea until I thought about alphas, in my case it's going to switch from 1 to 5 to 1 as I go into the gybe. Just have to use 5hz for alphas I guess.

The seal open showing how it fits into the actual usb port. This should help to seal it better.

The door hinges on a tie and can be pivoted aside

Maybe if the door was a rubber or silicon plug there would be half a chance it would seal, but hard plastic won't do a thing
