Subject: GPSD - NTRIP Client

I have been using GPSD for the past 5 year with a u-blox GPS and have been pleased with the performance.  The project that uses this configuration is about to go through a redesign and I have been trying to prototype part of the configuration.  The current prototype consist of :

RaspberryPi 4 running Buster OS

Raspian 4.19 Sept2019 release

GPSD (Version 3.17 )  was installed from app-get


GPS :   u-blox – ZED-F9P


We are using the F9P so that the system can get to RTK accuracy.

For RTK base-station reference the project will be using NTRIP casters. Since we are in NewYork the initial testing is using the NYS CORS network.   I have been able to use the U-Center application  ( ublox software)   and connect to the CORS network and push this data to the F9P.


When I have tried using the “ntrip” command line option as a part of gpsd, gpsd reports the following error:


gpsd:ERROR: ntrip stream connect error -2 in req probe

gpsd:ERROR: initial GPS device ntrip://UUUUUUUUU:address@hidden:8082/NYPF open failed



Here is the NTRIP listing for the NYS CORS network:


MountPoint      Single Site                    Satellites     Type                     Message Type             Port            ProductName                

NYPF                   Pittsford – NYPF        GGG              Single site           RTCM3.x(MSM5)        8082           R_NYPF


This is the command string I am using:

gpsd -n /dev/ttyACM0 ntrip://UUUUUUUUUUUU:address@hidden:8082/NYPF -N -D 5     ( username and password are filled out correctly )


gpsd is getting valid Lat/Lon from the device.



How can I get gpsd to use the NTRIP data from NYS CORS?

If you need more information let me know.




Thank you
