Ok. Thanks to everybody for their input. I've got my gps reading consistently every second. My highest Hdop is 1.4. If I do get 3.0's or higher do I discard that alpha, can I delete a track point or spike? How does this affect the data? What parameters do the captains of teams use when the verify PB's etc??
I'm still not getting a smooth track like other get. Where is the best update for the firmware? Can someone post the link. This is a last resort, as I have done everthing else!!
I'll start again with both units and see how that goes.
try this one Tomhttp://mtbest.net/setting-up-navi-GT31.htm
I still think the gps may be obscured when you gybe, especially in the unit isn't facing up when you lean over. Try rotating it on your arm so that it's almost facing backwards, bit harder to read, but it'll be facing the sky when you do a radical laydown.
Verify PB's?????? Who does that? Certainly not Hardie.
There really is very little verification done these days. It's probably something we should do more with PB's and top rankings.
For Alphas there are no published guidelines for HDOP or SDOP maximums. I think the SDOP is much more important but the catch is that RealSpeed does not display it.
The good news is that I have checked a few of the best Alphas which I have the files for and I have not seen any significant problems yet.
Ok now we are narrowing things down
.
I sailed 2 locations today. Stroppo was nice enough to lend me his GPS. Before going out I made sure all settings were identical. The only difference:
My gps Version 1.4(B0803T)
Strop's gps Version 1.4(B0315C)
I put Stroppo's unit in antenna-down in my case (worse scenario), and wore it the same as the other day, when I first discovered the problem. Here are the results. My GPS first:
Very interesting.My gps was the top one, antenna up. Stroppo's below it facing antenna down. His still read 2 more satellites with a smooth track
.
is it the version. I'll upload the same version as his to one of my units and keep the other the same for my next session.
For what it is worth, I don't think it is the firmware version that is the issue. It is the same version I have with no problems.
I would definitely reload the firmware though, making sure to follow Tom's instructions diligently.
If you didn't have two GPS doing the same thing I would say it was a hardware fault.....
Good diagnostics Tom, that eliminates my obscuring theory, be very interesting to see what firmware change does.
Ok
. Now i'm getting angry. Or is it frustrated.
Re-installed both units with 2 different versions of firmware. Sailed first half of session with both units in the same case as before. Same problem as before!
Took the new GPS out on it's own, in a lightweight case and wore it on my shoulder. Perfect view of the sky etc. Still not good. I don't get it!?!?!
Have you contacted Locosys?
You seem to be narrowing down to a problem with the units.
WWA has loaner BGT-11 units if you need to send them for warranty claim.
still waiting to hear back from them Lao. It's been 3 long days......too long
. I really think it must be the units, but 2?? Bit strange.
The bad thing is a lot of random peoples files from KA72 have the same problem.....lots!
Stroppos on call this week so I might try to grab his. At least that way I can register a decent alpha.
. If I'm coming north I might grab one off you. Just another comparison.
Whohooooooooooooooo! Found the solution.
Feel a little silly, but, it's all about learning. And once again, something my dad taught me (attention to detail is paramount) would have saved the day.
4 words: SETTINGS - POWER MODE - NORMAL (had mine on low power mode)
I'm just happy to have good data now
. Thanks to everyone that tried to help. Lots of random tracks I looked at on KA72 had the same problem so check you settings
$130 + postage if you look around. but see Paul at Second Wind, best deals yet!!
thanks for the answer guys, asking cause the naish dealer is closing and he's selling them @ 100$
