The 2 types of services which is provided by IRNSS. They are SPS and RS. The Two frequencies are allotted for these services which is operated on L5 band (1164.5MHz) and S band (2472.5MHz) band. Thet code is utilized, some part of SPS is Psedo Ranging clamour codes. It utilizes gold codes, gold codes is used for transmission of the navigational data in downlink SPS. PRN code sequences is a secondary code and thet gold code defined as a primary code. The GPS works based on CDMA in that Pseudo Random Clamour sequences which are required for the systems. In this letter a study is made on generation and Analysis of SPS pseudo random clamour codes from the view point of navigational system. This letter shows the design and analysis of Pseudo random clamour code on Spartan-6 FPGA board. The obtained Pseudo random clamour code outputs, which are approved from hardware with the simulation results. The simulations of SPS Pseudo random clamour codes were obtained utilizing Xilinx ISE test system and the simulated results are within the theoretical limits.
