Subject:Problem in netxml file with GPS "avg" datas
Date:10:28:28 15/11/2011

Hello,
I use Kismet Newcore with a Holux GPS Tracker. Everything is fine except the three datas avg-lat, avg-lon and avg-alt in the section <gps-info> of the "*.netxml" files. Both min, max and peak values are correct, in *.gpsxml and *.netxml. For example, the avg-alt is often set to approximately -170000 meters !
There are two cases : The correct one
<detection-run kismet-version="2010.07.R1" start-time="Thu Oct 28 15:38:40 2010">
<gps-info>
<min-lat>48.120575</min-lat>
<min-lon>-1.625915</min-lon>
<min-alt>46.200001</min-alt>
<min-spd>0.000000</min-spd>
<max-lat>48.123577</max-lat>
<max-lon>-1.625052</max-lon>
<max-alt>91.500000</max-alt>
<max-spd>0.000000</max-spd>
<peak-lat>48.121563</peak-lat>
<peak-lon>-1.625575</peak-lon>
<peak-alt>66.599998</peak-alt>
<avg-lat>48.121414</avg-lat>
<avg-lon>-1.625585</avg-lon>
<avg-alt>66.320414</avg-alt>
</gps-info>

The problem file :

<detection-run kismet-version="2011.03.R2" start-time="Tue Nov 15 12:25:52 2011">

<gps-info>
<min-lat>48.121395</min-lat>
<min-lon>-1.625507</min-lon>
<min-alt>49.900002</min-alt>
<min-spd>0.000000</min-spd>
<max-lat>48.121468</max-lat>
<max-lon>-1.625373</max-lon>
<max-alt>52.099998</max-alt>
<max-spd>0.000000</max-spd>
<peak-lat>48.121437</peak-lat>
<peak-lon>-1.625507</peak-lon>
<peak-alt>52.099998</peak-alt>
<avg-lat>-166.626939</avg-lat>
<avg-lon>-176.108484</avg-lon>
<avg-alt>-174431.887100</avg-alt>
</gps-info>

Values seems to be always correct in 2010.07.R1, while sometimes uncorrect in 2011.03.R2.

Thanks for help.
