You need to read the H/W manual for the GPS module you have to see what protocol it uses.

What sort of GPS module? What make and model? How is it connected to your computer? Serial, TCP/IP, PCIe card?

Every GPS that I have worked with were NMEA compatible and don't require any type of query to get information out.

They just constantly transmit NMEA Sentences at regular intervals.

What sentences and how often they are sent is totally dependent what sentences the manufacturer decided to support and how often they decided to send them. 

The "NMEA default" for GPS serial communications is 4800 baud 8 bit No parity 1 stop bit. But newer GPS can often be set to transmit at a high baud rate.

You will have to consult your GPS manual for any settings that can be set and how to set them.
