    Completion of the QiTai Radio Telescope Antenna Track Foundation

    Date:Sep 23, 2024【 A  A  A 】【 Print 】【 Close 】

    On September 20, the final step in constructing the telescope track foundation girder ring beam for the QiTai Radio Telescope (QTT) was completed, marking the beginning of the main antenna structure installation.

    The QTT is the first major scientific research infrastructure project in Xinjiang. With a 110-meter main reflector, it will be fully steerable, highly sensitive, and designed for multi-disciplinary observations across a frequency range of 270 MHz to 115 GHz. Since the construction began, the QTT project team has finalized both the overall and detailed designs of the telescope.

    QTT will be the world's largest ultra-high-precision, large-aperture radio telescope for 3mm observations, with pointing accuracy being crucial for this capability. The antenna track foundation is vital for ensuring the telescope achieves the necessary pointing precision. The completion of the girder ring beam marks the end of the track foundation construction, allowing the project to officially move into the installation phase for the main antenna structure. This next phase will focus on installing the antenna’s mechanical structure, a critical component that provides a stable, reliable, and high-precision platform for the telescope’s electrical performance during observations. The Xinjiang Astronomical Observatory is fully committed to ensuring the telescope's high-quality construction.
