Questions about Netstumbler

giorger · 08-11-2008

Hi..
I have the following questions regarding the operation of Netstumbler. I tried to find the answers by reading the other topics/forums but i could not find something relevant. So...
1) Netstumbler uses Windows time. Can I set it to synchronize with GPS? (pretty useful to log using gps time)
2) Netstumbler scans for wifi by capturing whatever it finds or by probing (causing the Access Point to respond) (passive or active scanning mode)?
3) Is the GPS signal filtered by any means like number of satellites or DHOP (or anything else)?

GPS time and your system time should be the same, if not, then your system time is wrong. Netstumbler is an active network scanner. No gps signal filtering.

Checking the logs of netstumbler, found no way to filter manually GPS data. Thus, GPS logged data contain sometimes great faults (for example I was wardriving in Greece but shown as if I was in Russia). The only way for filtering is to keep a separate file with raw gps data (dump data from a COM port to a file)?

Use helper app like GPSGate GPS splitter, simulator and logger. Serial port splitter. - Franson GpsGate
It will give you a more stable connection which is probably the cause of the discrepancy.

BTW, there was talk of it syncing time with the PC so you might want to investigate that to see if it's been implemented yet.
