Here are some things to try;
See if it works with minicom;
minicom -b 9600 -o -D /dev/serial0
Try and reset GPS module; (may need to kill gpsd with ‘sudo killall gpsd’)
gpsctl -f -t u-blox -x '\x06\x04\xff\xff\x02\x00' /dev/serial0
Check if you console works;
1. on the Pi, connect TX to RX with a jumper cable.
2. start minicom minicom -b 9600 -o -D /dev/serial0
3. type some characters, if you see them on the screen then your console is working.
