How to read the VK2828U7G5LF GPS module using DE0-Nano

Hi, i'm a newbie to the fpga.

I'm facing the problem when i try to read the data directly from a VK2828U7G5LF GPS module because the DE0-Nano without going through the PC.

The GPS interfacing can be UART/TTL and RS232 is optional to use.

i'm more likely to interface the GPS directly to the DE0-nano and decoded the data acquired.

Can anyone help me in this problem or any suggestion.

Thank you.
