DISCOSClient is a Python client for accessing telemetry data streams from DISCOS (Development of the Italian Single-dish COntrol System), the control system used by INAF's radio telescopes.

The client allows subscriptions to specific components (e.g., mount, antenna) and provides thread-safe, read-only access to their internal state via a structured and immutable interface.

• ZeroMQ SUB client for structured telemetry updates
• Read-only nested namespaces for safe access
• Lightweight and dependency-minimal
• JSON schemas used as metadata for message structure

Clone the repository and install the package:

git clone https://github.com/discos/DISCOSClient.git
cd DISCOSClient
pip install .

from discos_client import DISCOSClient

SRT = DISCOSClient("mount", address="127.0.0.1", port=16000)

az = SRT.mount.azimuth.currentPosition
el = SRT.mount.elevation.currentPosition
print(f"Azimuth: {az}\nElevation: {el}")
