OziExplorer indiscriminate spikes in plot trails?

DJ,

I also have the same problem running version 3.90.4i. I used to think it was only when I started the car, but it seems to happen at anytime. Sometimes I can go weeks without it happening and on some trips I can get it quite a few times. I usually just end up manually editing the track file in order to get rid of the spikes.

I suspect it maybe a satelite lock issue, but who know!!!!

Regards

Dave

Why not ask on the oziexplorer website?????????????????????????????????

This is probably caused by a phenomenon known as multipath error. Briefly, GPS receivers work by receving satellite signals and measuring how long they take to arrive, which is a very tiny amount of time. The receiver assumes the signal has travelled directly to it.

If the signal bounces off objects then it takes longer to get to the receiver, and may be received twice. This confuses the receiver, usually temporarily, and is often seen as weird speed spikes in the maximum speed, or bizarre locations.

Yeh, I noticed this just recently.
At the time I was periodically saving the plot trail for good measure, and ended up with heaps of these direct lines back to probably where I last saved it.
I stopped saving it till I shut down the machine each night, and the problem stopped. Only thing is one must start a new plot each time one starts up; ie, can't append to the original.
Don't recall this happening on earlier versions. I use the latest v3.95.
Check out the OziExplorer forum on Yahoo, there might be a thread.
Cheers,
Gerry
