Today, I am going to provide a brief description on interfacing GPS receiver with AT89s52( a microcontroller from 8051 family). The GPS receiver used is GT3221R. The specification of this GPS receiver (GT3221R) can be found in the manufacturers website.Before we go to this post first it is recommended to read a post on serial communication using AT89s52. First, I will be telling how this GPS receiver works and then we will go in the process of interfacing it with AT89s52.
