- Small and light (7.7×4.3×1.8 cm, 55 g)
- Quick fix and keeps working under foliage, underneath trees, inside some buildings/structures and often inside trains.
- Goes a long way on one battery charge
- High memory capacity
- Can be used as a GPS mouse (BT) (NMEA output)
- It has two antislip 'feet', that (when new) allow it to be stuck against a window
- Battery can be replaced and is Nokia BL-5C (other similar models will probably work too)
- GPS traces seem to be "smoothed" sometimes - it's cutting corners when not under a clear sky. I see it do that mostly under foliage. This is weird, since it would have to 'calculate' those points. It would be better if it would simply interrupt writing points. Maybe this is something that happens during the conversion of the internal format over kml to gpx.
- Not possible to reset logs without a PC; i.e., there is no application to do so from Windows Mobile and for Linux
- No external antenna (not needed either)
- Only a charger for in the car is deliverd with it, no mains. It's a standard mini-USB connector though, so it can be charged from a computer as well or with this: Keomo Charging Bank External Accu (2200 mAh). The USB connector does not connect to an internal USB-port. So no USB connectivity only BT.
- Data format ( .log, .logg ) seems to be non standard. See comment below.
- Not supported by gpsd. Therefore also no support for GpsDrive and other software relying on gpsd.
Dedicated PC application can be used to read the log, clear it, and convert it to kml (Google Earth) format. It can also be used to read out the live position (NMEA).
- When you get one and you are using Windows Vista. It may be necessary to do the following: Rename the tool that is on the CD-ROM from .exe to .rar and 7zip or WinRAR to open and start using it.
- The Windows software which came with the device can convert the proprietary data format (.log, .logg) to Google Earth's .kml though. Linux's gpsbabel can translate this to gpx which in turn can be read by (e.g., JOSM). Note that .gpx files created from .kml files lack time stamps, hence are not suitable for upload to the OSM Server. (i have a small app that adds time stamps to this style gpx-files! Please contact me at wiYlcken@gmaYil.com (remove the 'Y's !!!))
- *Martin* 20:19, 15 December 2010 (UTC): If your gpx lacks timestamp, you can use this:
xmlstarlet ed -N x=http://www.topografix.com/GPX/1/0 -N y=http://www.topografix.com/GPX/1/1 \
-s '//x:trkpt|//y:trkpt' -t elem -n time -v 1970-01-01T00:00:00Z track.gpx > track-nulltime.gpx
