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. http://www.hellis.me/GPS.zip 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. So? Would you think a new GPS would help me? Today i use my cellphones GPS, (sony ericsson P1i with a [url="http://www.semsons.com/robtgpsxrsii.html"]Royaltek[/url] GPS) and i use [url="http://vlkgps.sourceforge.net/"]vlkGPS[/url] to log it on my phone. What i would need is a GPS that: [list][*] Creates a similar csv-file. [/*][*] Barometer or quick reliable altitude reading [/*][*] At least 1 hz, the more the better. [/*][/list] Any GPS that you could recomend? Display is not improtant (actually *not wanted*, a bad landing might crack it) [/quote]   Check here to include your profile signature.
