[Elphel-support] 答复: 答复: 答复: sync stereo with lidar

[Winston Zhang]

Hi, Oleg

      We tried the USB GPS and it worked. The system could detect the device. And 192.168.0.9:2323/meta<http://192.168.0.9:2323/meta> had GPS related tags. That info was just showed on the web. I could see it but I could not get it. Do you know how to get it?

      Another question is the two camera timestamp are not the same no matter whether or not we connect the gps.

Hi,

Olga will send you a quote.

Meanwhile, you can test your USB GPS.
Plug it in the "eSATA+USB" port (https://wiki.elphel.com/wiki/File:NC393-CS_marked_ports.jpeg)
Then to check if it's working:
a.
$ ssh root at 192.168.0.9<mailto:root at 192.168.0.9>
elphel393~# dmesg | grep Garmin
[   47.236566] usb 1-1.4: new full-speed USB device number 3 using ci_hdrc
[   47.398450] garmin_gps 1-1.4:1.0: Garmin GPS usb/tty converter detected
[   47.405759] usb 1-1.4: Garmin GPS usb/tty converter now attached to ttyUSB0

b. 192.168.0.9:2323/meta<http://192.168.0.9:2323/meta> will have GPS related tags:
...
<GPSMeasureMode>"2"</GPSMeasureMode>
<GPSDateTime>"2018:05:07 22:29:14.00"</GPSDateTime>
<GPSLongitude>"-111.885652"</GPSLongitude>
<GPSLatitude>"40.780143"</GPSLatitude>
<GPSAltitude>"1378.200000"</GPSAltitude>
...

If b. works then camera images are geotagged.
