GPS Configuration txt file

[fgmultiwii]

is there anyone that can help me for configuring and making work the GPS on my Multiwii FC with Mega 2560 ( Hextronik ).
The GPS module is Ublox LEA-6H by Hextronik. I would like to know where I can find the right u-blox-config.ublox.txt file as mentioned in the code below.
My running software on FC is Multiwii_pre24_r1729 and in the config.h section I setup the following:
#define GPS_SERIAL 2 // should be 2 for flyduino v2. It's the serial port number on arduino MEGA
#define GPS_BAUD 38400 // GPS_BAUD will override SERIALx_COM_SPEED for the selected port

/* GPS protocol
NMEA - Standard NMEA protocol GGA, GSA and RMC sentences are needed
UBLOX - U-Blox binary protocol, use the ublox config file (u-blox-config.ublox.txt) from the source tree
MTK_BINARY16 and MTK_BINARY19 - MTK3329 chipset based GPS with DIYDrones binary firmware (v1.6 or v1.9)
With UBLOX and MTK_BINARY you don't have to use GPS_FILTERING in multiwii code !!! */
#define UBLOX
Thanks
