Hi,

I have the script installed on the raspberry pi image from https://www.sdrplay.com/raspberry-pi-images/ version V 0,6. I did managed somehow to get the GPS GNSS donlge (Bus 001 Device 005: ID 1546:01a8 U-Blox AG [u-blox 8]) https://www.amazon.de/gp/product/B07SMRXSC8/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 using the following instructions:

_GPS for Raspberry pi lsusb sudo apt -y install gpsd gpsd-clients python-gps sudo nano /etc/default/gpsd

Add this to file

START_DAEMON=”true” USBAUTO=”true” DEVICES=”/dev/ttyACM0″ GPSD_OPTIONS=”-n” save & exit sudo apt-get install chrony

check to see if services are running

systemctl is-active gpsd systemctl is-active chronyd

Check GPS output

cgps – s gpsmon -n

Edit chrony config file

sudo nano /etc/chrony/chrony.conf

Add this to end of file

refclock SHM 0 offset 0.5 delay 0.2 refid NMEA

Check Chrony Output

sudo chronyc sources -v

Check chrony output

sudo chronyc tracking

Force time sync

sudo chronyc makestep

if still not working: dmesg | grep -i tty sudo cat /dev/ttyACM0 sudo gpsd /dev/ttyACM0 -F /var/run/gpsd.sock cgps -s_

The Problem is that with the SDR device RSP1a plugged in it dose not work. It seems to start working once I unplugged it becasue Conky was showing the gridsqare but then it showed NO GPS.

Please add the suport for the new dongle and tell me if I did something wrong or if there is something else that I should do in order to have it running mostly for time sincronization.

Thank you and 73!, Catalin, DE1CTL
