This document analyzes and simulates pseudo ranging noise codes for geo-stationary satellites, including their Doppler effect. It examines the auto-correlation function and cross-correlation function properties of Gold codes, Kasami codes, and their truncation effects. The simulations were performed using MATLAB and System View. The results show that truncating the codes degrades their correlation properties. Doppler frequency shift on carrier frequencies and codes for geo-stationary satellites was also analyzed and found to be negligible.
