Anyone know of a good windows / pda based gps log file analyser?

I'd like a nice windows one with telemetry. Have only found a basic one for pda which just gives max speed attained and altitude...

TomTom GPS has a GPS log IIRC.

Not sure what exactly it does, as i haven't tried it yet

it records the details of your journey, you can then play it back later and see your speed etc. Need to test it at the ring sometime, especially now I have the tomtom3 germany map, and yes the ring is on it.

Xavier I have been looking for a simillar thing, something that would show average speed etc..

Geoff, yes, it does have the gps logging facility.

You can play back a log with it and it will show you data, but it's not very friendly - it shows exactly the same stuff as what you see on the gps screen. Although it has speed, N&W coords and satellite reception, it's not the easiest way in which to interpret the data.

I would hope the log is in a standard format.

Looking at the file it produces:

There are obviously a set of parameters such as $GPGGA, $GPGLL, $GPRMC, $GPVTG, $GPGLL, $GPGSV... with data. Just need to figure out how to interpret the data, and at what frequency it is updated.

Hmm, thinking about it:

$GPRMC,124606.051,A is probably the altitude, 5229.0654,N North coords, 00108.9582,W West coords, 8.68,056.0,240404,,*25 time/date (24/04/04 rings a bell anyone? )

Would that happen to equate to Bruntingthorpe by any chance!
