so, why i can't get no gps fix? can anybody say what there is to do with this issue?

[Mortific]

Is the gps reciever set to NMEA output? If you run gpsmon, what does it report?

[msfu101]

No it's not,
the output of gpsmon is

tcp://localhost:2947 JSON slave driver>
(82) {"class":"VERSION","release":"3.20","rev":"3.20","proto_major":3,"proto_minor":14}
(32) {"class":"DEVICES","devices":[]}
(122) {"class":"WATCH","enable":true,"json":false,"nmea":false,"raw":2,"scaled":false,"timing":false,"spl
it24":false,"pps":true}

I don't know what i am doing wrong.

if i run sudo ./crocodilehunter.py -d -w
i get this output

[msfu101]

/usr/lib/uhd/utils$ sudo ./query_gpsdo_sensors
it says this

gps_locked sensor not found. This could mean that you have not installed the GPSDO correctly.

Visit one of these pages if the problem persists:

• N2X0/E1X0: http://files.ettus.com/manual/page_gpsdo.html
• X3X0: http://files.ettus.com/manual/page_gpsdo_x3x0.html
  anyone an idea? i can*t get it

[Mortific]

It seems like the gpds service is not getting a position from the gps.

1. Do you have a GPS receiver with usb? Is there a way to verify that the gps is getting a signal and gps fix? In my case when the led flashes on the GPS receiver, I have a gps fix. Fixed light means operating but no signal.

2. Have you installed and started the gpsd sevice according to installation instructions?

3. Is [Devices] in the config file pointed to the right USB port connected to the gps?

Edit: spelling

Problem solved. It was a wrong configured gpsd.
