Hello all! Im new here
Im looking for a new GPS logger since the one that i use today seems to be too slow.
The problem i get is mostly that the altitude is not correct, other data seems to be correct.
So i think i need one with Barometer or a better (quicker more accurate) GPS when it comes to altitude.
Let me start off with showing what i get from my current GPS.
The csv-file is the "raw" data from the GPS, then i use a Ms Excel macro to get the xls(x)-file.
The xls(x)-file shows the skydive.
According to the GPS i hit the ground (row 84) at about 140 km/h, which is not true
And thats the problem, since the altitude is so off i start to question if the other data is correct.
The glideratio depends on a correct reading of altitude.
The distance traveld is also depeniding on the altitude.
Would you think a new GPS would help me?
Today i use my cellphones GPS, (sony ericsson P1i with a Royaltek GPS) and i use vlkGPS to log it on my phone.
What i would need is a GPS that:
- Creates a similar csv-file.
- Barometer or quick reliable altitude reading
- At least 1 hz, the more the better.
Any GPS that you could recomend?
Display is not improtant (actually *not wanted*, a bad landing might crack it)

Edge 800 has one. Also temperature sensor too

By construction altitude is the last accurate dimension of GPS so no surprise here, also keep in mind that there a geodectic correction is needed, your current setup may or may not handle it properly -> http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=10915
As for loggers with a barometer, none that I'm aware of, but there are handheld systems with a barometer, like the Garmin Colorado, Oregon, Dakota. Not sure they can feed live data that shows a barometer based altitude.
