Project Story

From local reflector design to a scientific radio astronomy platform

Follow the development path from the first initiative and local engineering decisions to observation, calibration, and scientific interpretation.

Timeline

Development path

The project grew from an initiative and early collaborations into telescope engineering, university deployment, scientific observations, and later integrated hardware/software work.

University Deployment

The project expanded into a university network. The 2025 IEEE paper reports replication across five Saudi universities at the published implementation stage.

Fixed Telescope Limitations

The historical fixed zenith-pointing system used Earth rotation for transit scanning, while later material motivates automated pointing.

Pointing and Observation

From celestial position to spectrum

The portal separates the published fixed transit-scan concept from later moving-telescope capabilities.

Historical fixed system

In the published fixed implementation, the telescope points at zenith and Earth rotation carries sky regions through the beam. This supports transit-scan measurements without implying motorized tracking.

Moving-system concept

For moving systems, a sky target in RA / Dec can be transformed into azimuth / elevation, sent to telescope pointing, and then measured as a spectrum.

Engineering to Science

What the platform makes possible

It receives H I emission, processes and calibrates the signal, connects observations to sky coordinates and velocity, and supports an educational and scientific view of the Milky Way.
