FR-AI / ANALYSIS

Why it is worth attention

It streamlines an end-to-end GNSS processing workflow from data download to PPP-AR analysis, targeting atmospheric research with built-in scientific defaults like VMF3 mapping and stochastic ZTD.

Who it is for

  • GNSS researchers working on atmospheric studies
  • Geodesists using precise point positioning
  • Atmospheric scientists needing tropospheric delay estimates
  • Users of PRIDE PPP-AR who want automated data handling

Use cases

  • Downloading and processing Hong Kong SatRef data for zenith total delay (ZTD) time series
  • Automated batch processing of multiple stations over several days
  • Reproducible atmospheric research with consistent processing parameters

Strengths

  • Automated workflow combining data retrieval and processing
  • Scientific defaults (VMF3, stochastic ZTD, static PPP-AR) reduce manual setup
  • Integrity checks on output completeness, model, and temporal coverage
  • Non-destructive data policy: never removes raw RINEX files

Considerations

  • Requires external installations of PRIDE PPP-AR and hatanaka (with runtime tables)
  • Only supports Hong Kong SatRef network, limiting geographic scope
  • Network access needed when downloading data and precise products

README quick start

Hong Kong GNSS PRIDE plugin

A portable Codex plugin for downloading Hong Kong SatRef RINEX 3 observations and processing them with PRIDE PPP-AR for atmospheric applications.

Scientific defaults

  • Daily RINEX 3 observations at 30 s
  • Static PPP-AR
  • VMF3 mapping function
  • Stochastic ZTD and horizontal-gradient parameters
  • Output completeness, model, and temporal-coverage checks

Requirements

  • Python 3.10 or later
  • hatanaka providing rinex-decompress
  • A working PRIDE PPP-AR installation with runtime tables
  • Network access to Hong Kong SatRef and precise-product providers when downloading

Place pdp3 and rinex-decompress on PATH, or set:

export PDP3=/path/to/pdp3
export RINEX_DECOMPRESS=/path/to/rinex-decompress

PRIDE_PPPAR_HOME and HK_GNSS_PYTHON are also supported.

Install from this marketplace

codex plugin marketplace add huliyu040110/hk-gnss-pride-plugin
codex plugin add hk-gnss-pride@hk-gnss-research

Restart Codex or start a new task if the newly installed skill does not appear immediately.

Use

Invoke the bundled skill:

$process-hk-gnss-pride download and process all Hong Kong stations from 2026-05-10 through 2026-05-12 UTC

Data defaults to the active workspace's data/ directory. The workflow never removes raw RINEX files and replaces existing solution days only after an explicit request.

PRIDE PPP-AR and downloaded GNSS/product data are not included in this repository.

The plugin workflow and bundled scripts are released under the MIT License. PRIDE PPP-AR, Hatanaka, Hong Kong SatRef data, and external precise products remain subject to their respective licenses and terms.
