This repository contains two folders. The information about each of the folder is described as below.

     SPD_vp.bin -- This SPD file is generated from the corresponding SPD_vect_patt file.

     This folder contains all the source code files for implementing the star pattern recognition in C. Paths for the input of the SPD and the input star image will have to be changed.
