Getting Started with the ASTERIX Toolkit: Installation & First StepsASTERIX Toolkit is an open-source suite designed to work with aeronautical surveillance data encoded in the ASTERIX (All-purpose Structured EURopean Surveillance Information EXchange) format. It provides parsing, decoding, visualization, and processing tools that help developers, researchers, and engineers handle radar, multilateration, ADS‑B, and other surveillance feeds. This guide walks you through installation, key concepts, first steps, and basic examples to get a working environment quickly.
What you’ll learn
- System requirements and supported platforms
- How to install ASTERIX Toolkit (prebuilt binaries and from source)
- Configuration basics and key components
- Parsing and decoding ASTERIX data with example code snippets
- Visualizing records and basic troubleshooting tips
System requirements and prerequisites
- Supported OS: Linux (preferred), macOS, Windows (via WSL recommended for best compatibility).
- Python: 3.8+ (if using Python bindings).
- Java: 11+ (if using Java modules; many tools in the ecosystem provide Java APIs).
- C/C++ toolchain: GCC/Clang and CMake (required to build from source).
- Recommended: 8+ GB RAM and a multicore CPU for heavy decoding/visualization workloads.
Install these common prerequisites on Debian/Ubuntu:
sudo apt update sudo apt install -y python3 python3-venv python3-pip build-essential cmake git
On macOS (Homebrew):
brew update brew install [email protected] cmake git
Installation options
You can install ASTERIX Toolkit via three main routes:
- Prebuilt binaries / packages (if available for your platform)
- Python package (pip) — quick for Python users
- Build from source — full control and latest features
1) Prebuilt binaries
Check the project’s releases page (or organization distribution) for platform-specific installers. Prebuilt packages typically include command-line utilities and a GUI visualizer. After downloading, follow platform installer instructions; on Linux this often means extracting a tarball and placing binaries in /usr/local/bin or your PATH.
2) Python package (pip)
If the toolkit exposes Python bindings, install with pip in a virtual environment:
python3 -m venv venv source venv/bin/activate pip install --upgrade pip pip install asterix-toolkit
After installation, confirm by importing in Python:
import asterix print(asterix.__version__)
If there’s no official pip package name change “asterix-toolkit” to the actual package name used by the project.
3) Build from source
Clone the repository and build:
git clone https://github.com/example/asterix-toolkit.git cd asterix-toolkit mkdir build && cd build cmake .. make -j$(nproc) sudo make install
Adjust steps if the project uses a different build system (Gradle/Maven for Java modules, setuptools for Python modules, etc.).
Key concepts and components
- ASTERIX format: a binary, category-based format where each category defines a set of data items (e.g., Category 10 for surveillance, Category 21 for ADS‑B).
- CAT (Category) numbers: integers identifying record types. Know which categories your sensors emit.
- FSPEC (Field Specification): variable-length bitmap in each record that marks which items are present.
- Parsers/decoders: modules that interpret FSPEC and decode items into structured objects.
- Record streams: files or network feeds containing concatenated ASTERIX records (often from dump files, live feeds, or sockets).
- Visualization: timeline views, map plotting, and raw hex viewers to inspect decoded items.
Configuration basics
Most ASTERIX tools require or support a configuration file where you:
- Specify which categories to parse
- Map input sources (files, UDP/TCP ports) to parsers
- Configure logging level and output formats (JSON, CSV, database)
- Set timezone, coordinate reference system, and projection for visualizers
Example config snippet (YAML-style):
input: - type: file path: /var/data/asterix/dump.cat8 - type: udp host: 0.0.0.0 port: 4950 categories: - 8 - 10 output: format: json path: ./out
First steps — parsing a sample file (Python example)
Below is a minimal Python example showing how to open a recorded ASTERIX file, decode records, and print a few fields. Adjust imports and API names to the actual toolkit implementation.
from asterix import AsterixReader # adjust to actual module name reader = AsterixReader("sample_cat10.bin") for record in reader: # record.category, record.timestamp, record.fields etc. print(f"Category: {record.category}, Time: {record.timestamp}") if record.category == 10: radar_id = record.fields.get('I010/010') # example field specifier pos = (record.fields.get('I010/080_lat'), record.fields.get('I010/080_lon')) print("Radar ID:", radar_id, "Position:", pos)
Common fields vary by category; consult the toolkit’s field mapping documentation or the Eurocontrol ASTERIX spec.
Visualizing records
If the toolkit ships a GUI:
- Launch the visualizer (often a command like asterix-viewer or a GUI jar).
- Load your input file or connect to a live feed.
- Use layers to show aircraft tracks, plots, and ground stations; configure map tiles (OpenStreetMap recommended).
- Toggle raw/decoded views to inspect FSPEC and hex payload.
For simple map plotting in Python, convert decoded positions to GeoJSON or use folium:
import folium m = folium.Map(location=[52.0, 4.0], zoom_start=6) for rec in decoded_records: if 'lat' in rec and 'lon' in rec: folium.CircleMarker([rec['lat'], rec['lon']], radius=3).add_to(m) m.save("tracks.html")
Common troubleshooting
- No output when reading feed: confirm UDP/TCP port binding, firewall, and that data source is sending ASTERIX frames.
- Unknown category errors: ensure your parser supports that category or add a category definition file.
- Incorrect positions: check units (degrees vs. scaled integers) and coordinate reference system.
- Build errors: install missing dev packages (libssl-dev, libbz2-dev), ensure correct Java/Python versions.
Next steps and recommendations
- Identify which ASTERIX categories you need and focus on their item catalogs.
- Run sample data through the toolkit to become familiar with field names and units.
- If using live feeds, set up robust logging and a small buffer to handle bursts.
- Explore exporting decoded data to CSV, JSON, or a time-series DB for downstream analysis.
If you tell me which platform (Linux/macOS/Windows) and whether you prefer Python, Java, or building from source, I can provide a tailored step-by-step install and an exact example using that environment.
