CF-18 GPS Issues

I bought a CF-18 a while back with a GPS module installed on it. For some reason when I use it the GPS appears to be rotating around randomly. The signal is all over the place.

I am currently running Windows 7 on this laptop and have gone through the Windows 7 installation instructions to the "T"...

I would really like to use this laptop for soil sample logging on the farm but the GPS is kind of holding me back right now. Any ideas on how to fix this issue?

I should mention this is on a CF-18KJHZABM model.

 

Do you mean you location on the screen is changing with out you moving?

 

A couple of things. What GPS do you have, OEM or ?, and what software are you using? Something you can try for free is to download VisualGPS, a free, very good GPS utility and see what you see. I have attached a screen shot, you are interested in the Survey Window. You should see a very small change in position, it will look like a random squiggle. That's the natural variation of your GPS's accuracy called DOP(dilution of position). Better GPS, smaller squiggle.

Be sure you zoom the survey window way in so you can really see the movement. Check back and let me know what you see.

Hi Capt.
Nosey Parker that I am I clicked your link and got "invalid attachment specified"
If only I had a clue what that meant...

Yep, 2 hours later working good.

 

I am going to guess it's a OEM GPS...the link works ok for me.

 

@unclemac, I was having issues with the image upload, you got to it before I got it fixed.
@catburton22, Perhaps I should expand a bit, if you already know this ignore it. Average consumer GPS is often touted as having 10 meter accuracy which is good enough for finding most stuff including your a**. It also means that you only know your position to within a circle 66 feet in diameter. If you leave and return you wont necessarily be in the same place in that circle. If that's not good enough we have to get better equipment.
I have never really put a factory internal GPS through its paces, the one in my traveling CF-18 has such a long cold start time I can't be bothered messing with it, so I have no idea how accurate it is. I'm guessing, from chit chat here on the forum that Panasonic OEM GPS in models CF-18, CF-29, and earlier, would have a hard time achieving even 10 meter accuracy. I will not get into the internal vs. external discussion here, there are plenty of threads on the subject already. Suffice to say there are a few people here, notably Toughbook and Ohlip who are Zen Masters of aftermarket internal GPS and they have generously shared their wisdom in multiple threads. I'm not bad with external GPS, and I can guarantee you sub-meter accuracy (think within 12" +/-) for around $40 and 1 minute of your time.

I'm not sure where I'm going, not sure where I've been, but I absolutely know where I am.

 

Well I guess your doing better than most of us :laugh:

 

Depends on where you are. There's always up the proverbial waterway lacking means of propulsion
