PPC Reproduction Commands

PPC-Dataset can be verified directly from an extracted dataset tree:

python3 apps/gnss.py ppc-demo \
  --dataset-root /datasets/PPC-Dataset \
  --city tokyo \
  --run run1 \
  --solver rtk \
  --require-realtime-factor-min 1.0 \
  --summary-json output/ppc_tokyo_run1_rtk_summary.json

Current Sign-Off Profile

Use ppc-rtk-signoff for the deployable status profile:

python3 apps/gnss.py ppc-rtk-signoff \
  --dataset-root /datasets/PPC-Dataset \
  --city tokyo \
  --realtime-profile sigma-demote \
  --rtklib-bin /path/to/rnx2rtkp \
  --summary-json output/ppc_tokyo_run1_rtk_signoff.json

Use ppc-coverage-matrix to replay the full six-run sigma-demote nis2-ratio4 profile:

python3 apps/gnss.py ppc-coverage-matrix \
  --dataset-root /datasets/PPC-Dataset \
  --preset low-cost \
  --ratio 2.8 \
  --carrier-phase-sigma 0.001 \
  --max-postfix-rms 0.2 \
  --max-consec-float-reset 10 \
  --max-subset-ar-drop-steps 18 \
  --adaptive-dynamic-slip-thresholds \
  --adaptive-dynamic-slip-nonfix-count 25 \
  --max-pos-jump 5.0 \
  --max-pos-jump-min 5.0 \
  --max-pos-jump-rate 25.0 \
  --demote-fixed-status-nis-per-obs 2 \
  --demote-fixed-status-max-ratio 4 \
  --output-dir output/ppc_sigma_profile_runtime_demote_nis2_ratio4 \
  --summary-json output/ppc_sigma_profile_runtime_demote_nis2_ratio4/summary.json \
  --markdown-output output/ppc_sigma_profile_runtime_demote_nis2_ratio4/table.md

Coverage Matrix

Use this for the README RTKLIB demo5 comparison table:

python3 apps/gnss.py ppc-coverage-matrix \
  --dataset-root /datasets/PPC-Dataset \
  --rtklib-root output/benchmark \
  --ratio 2.4 \
  --summary-json output/ppc_coverage_matrix/summary.json \
  --markdown-output output/ppc_coverage_matrix/table.md

python3 scripts/update_ppc_coverage_readme.py \
  --summary-json output/ppc_coverage_matrix/summary.json

Historical Diagnostics

Older selector, residual-reset, IMU bridge, and tail-cleanup sweeps are kept as benchmark diagnostics rather than README sign-off commands. See Benchmarks for the scorecards and reproduction commands, and PPC realtime gate outputs for the accepted/rejected runtime status-demotion profiles.

Provenance

The PPC summary records receiver_observation_provenance for the bundled survey-grade rover/base RINEX streams. Proprietary receiver-engine solutions are not assumed to be part of the PPC benchmark target.

RTK ionosphere sweeps can be run through ppc-demo, ppc-rtk-signoff, or ppc-coverage-matrix with --iono auto|off|iflc|est; PPC summaries record the requested value as rtk_iono. Ambiguity-ratio sweeps use --ratio <value>; PPC summaries record the requested value as rtk_ratio_threshold.
