I'm looking for a cheep gps device with external antenna and USB or RS232C interface that advertises NMEA-0183 compliance.
I would like to monitor wifi 802.11a link quality betweent 2 cars equipped with laptops. Cars move in motorway at high speed and I need precise information about their gps-position in order to calculate relative speed and acceleration.
In gpsd-website I found a not really update list of compatible gps devices and it's not easy to find them in Irish-shops!
a lot of device are not gpsd compatible because doesn't send real-time information and I need high packet frequency and best precision.
the best device that i can find is Garmin GPS18/USB
1 usec claimed accuracy
0.100 sec NTP time offset measured by comparison with the NTP time service and reported by gpsd.
Can you suggest me any device?
This is not wardrive although tested devices that you usually use could be useful...
thanks a lot
Of course, if you really wanted to have some fun, go to Wal-Mart late at night and ask the greeter if they could help you find trashbags, roll of carpet, rope, quicklime, clorox and a shovel. See if they give you any strange looks. --Streaker69
im just wondering how good is the gps at finding locating of the AP?
I would rather be hated for what i am,
Then loved for what i am not.
