atmel 89s52

Hi
Im working on my final year project .I want to interface Gps module via serial port with 89S51.can any body help me.we have GPS trainer ST2276 in our lab . that updates data every 1 second .how would i program my 89S52 board which has a serail port . how would i program 89S52 so that it can read GPS data.
i `ve checked the trainer by connecting it with PC at 4800 baud rate and on other hand i`m using 11.059 Mhz crystel with my 89S52 and connected it serially with PC at 1200 baud rate .now should i do to connect 89S52 and GPS trainer??

interfacing gps module with atmega

I have interfaced trainer with PC and seen its output on hyper terminal .Its NMEA standerd sentense of the form
$GPGGA,hhmmss.ss,llll.ll,a,yyyyy.yy,a,x,xx,x.x,x.x,M,x.x,M,x.x,xxxx*hh
GGA = Global Positioning System Fix Data
1= UTC of Position
2 = Latitude in degrees
3 = N or S
4 = Longitude in degrees
5 = E or W
6 = GPS quality indicator (0 = invalid ; 1 = GPS fix ; 2 = Diff. GPS fix )
7 = Number of satellites in use [not those in view]
8 = Horizontal dilution of position
9 = Antenna altitude above/below mean sea level (geoid)
10 = Meters (Antenna height unit)
11 = Geoidal separation (Diff. between WGS-84 earth ellipsoid and mean sea level. =
geoid is below WGS-84 ellipsoid)
12 = Meters (Units of geoidal separation)
13 = Age in seconds since last update from diff. reference station
14 = Diff. reference station ID#
15 = Checksum
VTG
$GPVTG, t,T,,, s.ss, N, s.ss, K*hh
VTG = Actual track made good and speed over ground
1 = Track made good
2 = Fixed text 'T' indicates that track made good is relative to true north
3 = not used
4 = not used
5 = Speed over ground in knots
6 = Fixed text 'N' indicates that speed over ground in knots
7 = Speed over ground in kilometers/hour
8 = Fixed text 'K' indicates that speed over ground is in kilometers/hour
9 = Checksum

thanks for your interest
