..we tried the above program and got the output as mentioned below:

I'm not able to get the longitude and latitude position..So kindly help me in this regard as soon as possible..

Why didn't you?

had you read the available material on GPS receivers, you would have found this "It can take 5 to 15 minutes before "Position" lock depending on available satellites and how clear the sky is from clouds or storms."
This delay is for the GPS receiver to make an ephemeris of the satellites it can see.
GPS RECEIVERS DON'T WORK WELL INDOORS. I own 2 of them and neither works great indoors.
When I complete the weather station I'm working on, The GPS receiver will be outside with a clear view of the sky and use radio's' for communication.

I use the program above to run the arduino, but always return with "0" SAT..

Any suggestion ??
