SIMURG PPP

SIMURG PPP is a Python client for running Precise Point Positioning workflows with SIMURG RINEX sources and a PPP processing service. It provides small command-line commands for individual PPP tasks, workflow commands for site/date processing, and an interactive terminal UI for selecting SIMURG sites and running batches.

The package is published as simurg-ppp and imports as ppp_client.

pip install simurg-ppp

TUI

Run simurg-ppp with no subcommand to launch the interactive terminal UI:

simurg-ppp

The TUI guides the SIMURG PPP workflow from the terminal. It can check service availability, verify external RINEX tools, select stored groups, choose dates, load processed SIMURG sites, select sites manually or from pasted input, and run workflow batches while showing progress and logs. Launching the TUI also creates config automatically on first run when no standard config exists; feel free to change it if needed.

Useful TUI options:

simurg-ppp --skip-startup
simurg-ppp --date 2025-11-11
simurg-ppp --storage-root workflow-data
simurg-ppp --select-only

For non-interactive site/date processing, use workflow commands:

simurg-ppp workflow start irkj 2025-11-11
simurg-ppp workflow proceed irkj 2025-11-11
simurg-ppp workflow status irkj 2025-11-11
simurg-ppp workflow report irkj 2025-11-11

CLI

Use the atomic commands when you already have a local RINEX file or a PPP task id.

Create configuration first if it is fresh installation and you didn't run TUI app.

simurg-ppp config init

config init creates the runtime config file and workflow storage layout in standard system locations when permissions allow it, or in standard per-user locations otherwise. Use --storage-root when you need a one-off storage override.

Atomic Commands

Verify optional external runtime tools:

simurg-ppp tools verify

Run the existing setup helpers through the installed CLI:

simurg-ppp tools install rtklib
simurg-ppp tools install hatanaka

Create a PPP task from a RINEX file:

simurg-ppp calculate irkj3150.25o

Check a PPP task status:

simurg-ppp check 0934dd49-0e75-47c9-a447-3728094929d7

Plot result series to a PNG. The default view is LLE: latitude with North/South error, longitude with East/West error, elevation with Up/Down error, and 3D error:

simurg-ppp plot 0934dd49-0e75-47c9-a447-3728094929d7 results.png

Use --xyz for the XYZ coordinate view:

simurg-ppp plot 0934dd49-0e75-47c9-a447-3728094929d7 results.png --xyz

Python Usage (API)

Run a single SIMURG site/date workflow from Python:

from pathlib import Path

from ppp_client.tui.workflow_runner import (
    WorkflowRunOptions,
    configure_logging,
    run_site_date_workflow,
)

configure_logging()
result = run_site_date_workflow(
    "irkj",
    "2025-11-11",
    WorkflowRunOptions(
        storage_root=Path("workflow-data"),
        force_start=False,
        poll_seconds=60.0,
        timeout_seconds=3600.0,
    ),
)

if not result.ok:
    raise RuntimeError(result.error)

print(result.report)

Use lower-level helpers directly when you want to compose your own flow:

from ppp_client import check_task, create_task, plot_result_points
from ppp_client.results import collect_result_points

task = create_task("irkj3150.25o")
details = check_task(task["id"])
points = collect_result_points(details)
plot_result_points(points, "results.png")

SIMURG Ecosystem

This package does not install a root simurg command. It exposes a future plugin entry point named ppp, so a later umbrella package can provide:

simurg ppp
simurg ppp workflow status irkj 2025-11-11

Development

Install the package in editable mode, then install development tools:

python -m venv .venv
. .venv/bin/activate
pip install -e .
pip install pytest twine build

Run checks:

python -m pytest -q
poetry check

Build release artifacts:

poetry build
python -m twine check dist/*
