WebbPRN Codes PRN = Pseudo Random Noise ¦Codes have random noise characteristics but are precisely defined. A sequence of zeros and ones, each zero or one referred to as a “chip”. ¦Called a chip because they carry no data. Selected from a set of Gold Codes. ¦Gold codes use 2 generator polynomials. Three types are used by GPS ¦C/A, P and Y Webb5 sep. 2024 · The problem is that the carrier is running three orders of magnintude faster than the PRN!!! Unless we zoom into one spot where the phase shift happens we can see …
WebbR = f/N. We assume that the PRN sequence will be modulated by the data at this rate, a rather natural rate for PRN modulation. B = 4f (approximately).

He also added information on topics such as PRN codes, multipath and refraction, clutter and MTI processing, and high range resolution.
