GPSGate problems

**Davefocus** · 05-02-2006, 10:06 AM

I've got GPSGate up and running for some desktop PC testing. The problem I have is that the imagery is not updating in FreeDrive. The speed and the direction (heading) are, but the imagery and lat/long aren't. I'm using a FreeDrive recorded log file. Do I need a GPSGate recorded log file or should FreeDrive recorded log file be ok?

Any suggestions,

Cheers,
Dave

My iGuidance log files work with GPS Gate. It's basically just a text file with a bunch of NMEA strings. Should look something like this.

Code:

$GPGGA,235844.568,3852.4739,N,07714.7751,W,1,06,1.2,72.1,M,-33.5,M,0.0,0000*7A
$GPGSA,A,3,10,29,02,04,30,05,,,,,,,2.4,1.2,2.0*3F
$GPRMC,235844.568,A,3852.4739,N,07714.7751,W,22.33,173.20,141205,,*26
$GPGGA,235845.568,3852.4677,N,07714.7741,W,1,07,1.0,72.4,M,-33.5,M,0.0,0000*77

Mine are kind of similar.

Code:

09:56:53|08|$GPRMC,085531.692,A,5239.9676,N,00033.5331,E,48.77,109.00,020506,,*36

09:56:55|08|$GPRMC,085532.691,A,5239.9630,N,00033.5544,E,48.79,108.88,020506,,*3F

09:56:57|08|$GPRMC,085534.691,A,5239.9541,N,00033.5970,E,48.96,109.34,020506,,*30

09:56:58|08|$GPRMC,085535.691,A,5239.9493,N,00033.6180,E,48.64,111.76,020506,,*39

Must be a setting I have got wrong. Any ideas?

Just take out the time then. You can ask CDRSkull, I guess.

And some progs are picky about what sentences are present. Using Viamichelin Nav Europe, i had to simulate sentences dealing with satellites in view and so on.

I ended up importing the file to excel, removing date stamp and sat locks columns, and then resaving as text file. After that I found that I just needed to tick the reset time box in GPSGate nmea logger. Oh well I'll remember for next time.
