Use the Earth rotation rate directly (not its sine) in the GEO velocity
coupling terms, compute the common orbital position/velocity once and
apply the GK-to-BDCS rotation only for GEO satellites, and document the
GEO PRN gate (C01-C05, C59-C63) with its ICD reference.
Compensate the Viterbi traceback delay when timestamping decoded SBAS
messages by carrying per-sample reception timestamps through the sample
and symbol aligners (removes a ~140 ms bias), with a deterministic unit
test covering the FIFO pairing.
Protect decoder state with d_setlock in reset(), set_satellite(),
set_channel() and general_work(), following the convention of the other
telemetry decoders.
Share per-PRN EMS dump files through a per-run dump session: the first
open in a run truncates stale data, later opens append, so channel
reassignments no longer wipe previously decoded messages.
- gnss_satellite.cc: accept the full supported SBAS PRN range (120-138)
instead of a stale 6-PRN whitelist that rejected valid PRNs such as WAAS
PRN 133. Per-PRN satellite/service names are no longer hardcoded, since
that assignment changes over time and cannot be reliably kept up to date
here (fixes review comments on PRN support and outdated satellite info).
- SBAS_L1.h: cap SBAS_L1_MAX_COHERENT_INTEGRATION_SYMBOLS at 1 (1 ms). The
telemetry decoder performs its own unsynchronized sample/symbol pairing,
so extending tracking's coherent integration to 2 ms is unsafe and
corrupts that pairing.
- sbas_l1_telemetry_decoder_gs.{h,cc}: carry an absolute per-sample/per-bit
timestamp through the sample buffer and Frame_Detector, replacing the
buggy offset that anchored the message timestamp to whichever sample was
current when decoding happened, which could be off by up to a full
message duration. Add
sbas_l1_telemetry_decoder_gs::compute_message_timestamp() as a small,
independently testable helper for the residual sub-bit correction, and a
matching deterministic unit test.
- sbas_l1_telemetry_decoder_gs.{h,cc}: implement a real reset() that clears
all decoder buffers/aligners and closes the dump file, so a channel
reassigned to a different PRN never mixes messages into the previous
satellite's file.
- Remove the orphan sbas_l1_telemetry_decoder.cc adapter: it includes a
header that no longer exists and is not part of any CMake target (the
factory instantiates the GNU Radio block directly), so it silently never
compiled.
- Dump file: overwrite instead of append on each run, remove the hardcoded
GNSS-SDR version string, and document that the .ems output is an
EMS-like raw message dump, not a conformant EMS file.
- conf/File_input/SBAS/gnss-sdr_SBAS_EGNOS_rx.conf: drop the outdated
PRN/satellite table and per-channel satellite comments, correct the
coherent-integration note to 1 ms, and clarify that SBAS is not used as
a ranging source in this configuration.

Extend the QZSS L1 C/A LNAV treatment to the L5 CNAV chain: the QZSS-
configured L5 telemetry decoder now publishes dedicated Qzss_CNAV_Iono
and Qzss_CNAV_Utc_Model objects instead of the shared GPS CNAV types,
and PVT keeps them in their own Rtklib_Solver members.
- RINEX 4.02 navigation files get "> STO J CNVX" QZUT records with the
UTC(NICT) identifier and "> ION J CNVX WIDE" Klobuchar records. The
WIDE subtype, compulsory for the QZSS CNVX ION message type, is
correct because CNAV Message Type 30 broadcasts the Wide Area
coefficient set (IS-QZSS-PNT-006; the Japan area set of Message Type
61 is not decoded).
- QZSS CNAV parameters no longer overwrite the GPS CNAV ones in mixed
configurations.
- The QZSS slots of the RTKLIB navigation structure take the LNAV
values with CNAV as fallback, and QZSS-only configurations keep
feeding the broadcast ionospheric model and the leap second count.
- The XML storage output gains qzss_cnav_utc_model.xml and
qzss_cnav_iono.xml.
The Klobuchar coefficients and the UTC(NICT) offset broadcast by QZSS
satellites in LNAV subframe 4 (both the wide-area and Japan-area pages)
were stored in the shared GPS structures, overwriting the GPS-sourced
values in mixed GPS + QZSS configurations and making it impossible to
label them correctly in RINEX output.
New Qzss_Utc_Model and Qzss_Iono storage classes are now published by
the QZSS-configured L1 C/A telemetry decoder and kept in dedicated
Rtklib_Solver members. With this in place:
- RINEX 4.02 navigation files get "> STO J LNAV" QZUT records with the
UTC(NICT) identifier and "> ION J LNAV" Klobuchar records, and the
LEAP SECONDS header is updated from QZSS data in QZSS-only setups.
- QZSS-sourced parameters are no longer mislabeled as GPS corrections
(GPUT / GPS ION or TIME SYSTEM CORR / IONOSPHERIC CORR lines).
- The QZSS slots of the RTKLIB navigation structure (utc_qzs, ion_qzs)
are now populated; QZSS-only configurations keep feeding the broadcast
ionospheric model and the leap second count as before.
- The XML storage output gains qzss_utc_model.xml and qzss_iono.xml.

Validate GPS and QZSS ephemeris map keys and PRNs when loading XML assistance. Restore QZSS system and satellite block metadata after deserialization, and load LNAV assistance for QZSS-only configurations. Guard RINEX generation against malformed records and missing satellite block metadata to prevent exceptions in the PVT worker.
- 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.
