There would be some of you that wouldn't know the capabilities of the little Garmin Quest GPS when it comes to Track , I have done a little demo on the web, If you have the need to record your every move then this one don't miss much,

Hi Doug,
Have you ever found errors in the log? I was checking my return trip from Pemberton on my Garmin GPS V and I have a few readings that are way out of whack.
For example I had a single speed reading of 138 km/hr, yet either side it read 101 km/hr and the time between readings was less than 10 seconds! - and all this while the cruise control was set for 100 km/hr!!! So i decided to
check further and my best reading was 209 km/hr yet either side was 76 and 81 km/hr - as
well as the leg course changing from 340 to 47 and back to 341 degrees in that time.
1111 29/12/2006 6:59:06 PM 102 m 116 m 0:00:02 209 km/h 47° true S34.51364 E115.99593
As this reading was only for 2 seconds, either I hit a time warp continuum or there is some inaccuracy in the track log. I once thought I could use this log to prove I wasn't speeding, but after seeing this
well I would lose my license for 209 km/hr!!!
Anyway, my question is have you seen anomalies like this in your logs or is it simply that my GPS V has an older processor and at times doesn't keep up with all the functions it is doing?
Cheers
Captain

Most Errors Captain are a result of insufficent antenna field of view and not the device.

Hi Robin,
I have a remote antenna mounted on my
snorkel and at the time I was travelling on the main road from
Northcliffe-Pemberton.
I agree a loss of sat cover would give this type of thing, but I would not expect that to have occurred at this instance . Besides, I never received the GPS warning that I had lost sat cover. And given that I found several anomalies like this, it has certainly cast doubt on my presumption that one could try and use this if caught speeding.
Cheers
Captain

I have also observed that type of reading without satellite loss indication Captain.
Your
snorkel sounds like a good spot. I believe that this however is the main reason and suspect you would have had more when internally mounted.
Never really got to the bottom of these things , but its feasible that radio signal
multi-path reflections can cause them.
I have verified that the "Planar" type of antenna mounted on a flat steel car roof causes less than the helical whip type I more commonly use.

Captain
I have read your query and the answers by others , Could be the old GPS your using too GPS V is going back a bit plus they don't have the acurate mapping we have now , I do know that the maximum speed has read way over what Ive done , it seems to acumilate if not zero'd , but No i have not noticed any errors in my logs.

Hi Doug,
I have updated my maps to version 7. Actually, I used the second unlock code of the Nuvi 660 to upgraded my GPS V - a bit of a bonus!
I think it is some form of processing error and given its only 1 or 2 readings in 1,000 I am not too worried.
Cheers
