I use a Qstarz - Receptor GPS Bluetooth Q890 Ultra compact with my N95 during kart race
My first test was awful because the gps was in my trouser pocket
Then I fix the GPS on my shoulder and I manage to get this KML file.
Does anyone managed to get better precision with this gps or an other.
here a link for the 16 lap of the race
Thank for your kml links
thank you to help me to optimise this

By the way you might like to know that you can input a KML file directly into google maps like this:

It looks like the GPS was NOT in 5Hz mode
here is my KML if you want to compare

I guess there is no chance in getting the driving lines visible in such small circuit. The lap time accuracy should be rather OK already with the current data.
PS. Can yo submit the track file please? (to http://www.racechrono.com/tracks/ )

Dimitry thanks for the google maps link,. I try download your kml and it doesn t work, i have an XML file instead...
I realy like to see other KML a 5htz to see the difference.
One more think, if you see all the 22 laps one bye one you see form time to time 1 or 2 who have more than 1or 2 metter of difference between 2laps. I dont understand why this gap it s like all the data are wrong.
How it is possible when you got 5 time perseconde the data from 8or 9 satellite...
I continue to use it to get my lap timing in realtime, it s fastess than waiting the data at the end of the race.
i compare laptiming with race chrono and official laptiming and it s not so bad :

The Gps is on my shoulder and i think his position is optimised
Do you have any KML file to see what other GPS recever give
Thank
