hello @khancyr
thank you for your reply
yes but i need to know about pixhawk parameters setup

there is no such thing as pixhawk parameter. Pixhawk is an electronics board, it does nothing itself.
So I will assume that you are using ArduCopter :
GPS_TYPE : NMEA Complete Parameter List — Copter documentation
SERIAL3_BAUD : your gps baudrate (probably 9600 which isn’t great) Complete Parameter List — Copter documentation
