Have you tried to stop GPSD and see what happens? I think it mighty be GPSD changing it back to 9600.
1. Stop GPSD
sudo systemctl stop gpsd.socket
2.change the speed on the GPS module to 115200
echo -e -n "\xB5\x62\x06\x00\x14\x00\x01\x00\x00\x00\xD0\x08\x00\x00\x00\xC2\x01\x00\x07\x00\x03\x00\x00\x00\x00\x00\xC0\x7E" > /dev/serial0
3.change the baud rate on Pi Serial
stty -F /dev/serial0 115200
4. check that you can still see the NMEA data at the new speed
cat /dev/serial0
5. change update rate to 10Hz
echo -e "\xB5\x62\x06\x08\x06\x00\x64\x00\x01\x00\x01\x00\x7A\x12" > /dev/serial0echo -e "\xB5\x62\x06\x08\x06\x00\x64\x00\x01\x00\x01\x00\x7A\x12" > /dev/serial0
6. wait and see if it changes back
