Thus octal 5111 corresponds tothe generator polynomial P 1 (x) = 1 + x 3 + x 6 + x 9 + x 11 .** The initial 11 bits also represent the initial condition, n 11, ……, n 1, for each PRN signalnumber. (See Figure 3.2-2)†The initial and the final bit values are obtained after dropping the initial bit value 0. Forexample octal 3266 corresponds to binary 1 1 0 1 0 1 1 0 1 1 0.12 IS-GPS-800A8 June 2010
