- Restore true chip semantics for L1: QZSS_L1_CHIP_RATE is 1.023 Mcps and QZSS_L1_CODE_LENGTH is 1023 chips again. The replica carries QZSS_L1_SAMPLES_PER_CHIP = 2 samples per chip (L1 C/A chips duplicated, L1 C/B sinBOC(1,1) subchips), following the Galileo E1 approach. The generated waveform is unchanged, but Tracking_1J.early_late_space_chips is expressed in chips again, consistently with all other signals. - Normalize the DLL discriminator with the sinBOC(1,1) correlation function when the tracked PRN broadcasts L1 C/B, selected per PRN in start_tracking(); warn if the configured correlator spacing falls outside the BOC(1,1) correlation main peak (> 0.33 chips). - Attribute L1 C/B observables and ephemerides (PRN 203-206) to the PRN of the satellite's nominal PNT signals (RINEX 4.00, Table 6), so RINEX, RTCM and rtklib identify the transmitting satellite correctly and multi-frequency observations of the same satellite are paired instead of counted twice. - Do not search QZSS L5 signals for PRNs above 202, which have no L5 PRN code assigned in IS-QZSS-PNT. - Remove reserved, non-operational PRNs 198 and 202 from the default QZSS search list; they remain selectable via the QZSS.prns option. - Fix a potential std::out_of_range in GNSSFlowgraph::priorize_satellites() when assisted acquisition prioritizes satellites of a constellation with only a subset of its signals configured.
