GPS/GPRS/GSM Module V3.0 part of my project.

Hello everyone
Soon there will be IT competition where i want to show my device. It will be with functions for SMS control, GPS real time information sent via SMS, PIR motion sensor,3 axis accelerometer and relay. The idea is that this device will start and take information when something happens like, activated from PIR sensor or moved and detected by accelerometer. Then will send SMS with coordinates and the reason why its activated. That if arduino didn't receive any command, after time e.g 10 minutes will launched relay.
I have this stuff:
Arduino Uno 
GPS/GPRS/GSM Module V3.0
PIR motion sensor
AC Adaptor 9V - 800mA 7.2VA
I tried this program code:

   longitude();    Serial.print("Dir:");    lon_dir();    Serial.print("Alt:");    altitude();    Serial.println(' ');    Serial.println(' ');  } }

but when i open Serial Monitor i receive only: 
"AT"
"AT+CGPSPWR=1"
"AT+CGPSRST=1"
"$GPGGA statement information: "
"UTC:" 
and thats it, nothing more. I know that GPS must be outdoor but i don't get 'inf' values. So I am new to developing with Arduino, and stuff like this so if someone can direct me to specifically useful information about that i want to make I will be really glad:)
