The PRN P-code set of 63 mutually exclusive sequences are describedin Section 3.2.1.1, and assignment of these code segments by SV ID number is given in Tables 3-Ia and 3-Ib. Anadditional set of 147 P-code PRN sequences are described in this section. Among the 147 additional sequences PRNnumbers 120 through 210 are reserved for other future GNSS applications. The P-code PRN numbers and their codesequences defined in Table 6-I are not for general use and will be approved, controlled, and managed by the GPSDirectorate.6.3.7.2.1 Additional P-code Generation.
The generation of 37 mutually exclusive P-code PRN sequences aredescribed in Section 3.3.2.2. An additional set of 147 P-code PRN sequences are generated by circularly shiftingeach of the original 37 sequences (over one week) by an amount corresponding to 1, 2, 3, 4, or 5 days. Theadditional sequences are therefore time shifted (i.e. offset) versions of the original 37 sequences. These offset Pcode PRN sequences, Pi(t), are described as follows:Pi(t) = Pi-37x(t + xT),where i is an integer from 64 to 210, x is an integer portion of (i-1)/37, and T is defined to equal 24 hours.As an example, P-code sequence for PRN 91 would be the same sequence as PRN 17 shifted 48 hours into a week(i.e.
1st chip of PRN 91 at beginning of week is the same chip for PRN 17 at 48 hours after beginning of week). Thecomplete list of the additional P-code PRN assignments is shown in Table 6-I. Any assignment of a P-code PRNnumber and its code sequence for any additional SV and/or other L1/L2 signal applications will be selected from thesequences of Table 6-I.As an example, P-code sequence for PRN 38 would be the same sequence as PRN 1 shifted 24 hours into a week(i.e. 1st chip of PRN 38 at beginning of week is the same chip for PRN 1 at 24 hours after beginning of week).
Thecomplete list of the additional P-code PRN assignments is shown in Table 6-I. Any assignment of a P-code PRNnumber and its code sequence for any additional SV and/or other L1/L2 signal applications will be selected from thesequences of Table 6-I.58IS-GPS-200F21 Sep 2011Table 6-IAdditional C/A-/P-Code Phase Assignments (sheet 1 of 5)C/APRNSignalNo.6465666768697071727374757677787980818283848586878889909192939495*G2 Delay(Chips)72969578080178873234320327389407525405221761260326955653699422188438959539879677586153792814446PInitial G2Setting(Octal)*First 10 Chips(Octal)**X2 Delay(Chips)P-code RelativeAdvance(Hours) **First 12 Chips(Octal)02541602116011141342002515231046040414451054007202620077052114001010144103650270026306130277156216741113124506060136025615501234152301750617066304351752025407311373033207231705151517001256037707670336141215071514116415000215010306640532117116411521022705432728293031323334353637123456789101112131415161718192021P27(t+24)P28(t+24)P29(t+24)P30(t+24)P31(t+24)P32(t+24)P33(t+24)P34(t+24)P35(t+24)P36(t+24)P37(t+24)P1(t+48)P2(t+48)P3(t+48)P4(t+48)P5(t+48)P6(t+48)P7(t+48)P8(t+48)P9(t+48)P10(t+48)P11(t+48)P12(t+48)P13(t-48)P14(t+48)P15(t+48)P16(t+48)P17(t+48)P18(t+48)P19(t+48)P20(t+48)P21(t+48)51120667211152664711416622515306476121525247573625753054360435205472441720253230573645752054320437205572445740052220333237773555In the octal notation for the first 10 chips of the C/A-code or the initial settings as shown in this table, thefirst digit (1/0) represents a "1" or “0”, respectively, for the first chip and the last three digits are theconventional octal representation of the remaining 9 chips.
