Combining RTK and TS to determine the position of array antenna of Mingantu Meter-Decameter Wavelength Spectral Radioheliograph of Chinese Meridian Phase II Projec

The newly built MUSER-L of the Chinese Meridian Phase II Project, and the existing MUSER-I and MUSER-H, are all solar dedicated radioheliographs, based on the principle of synthetic aperture and utilizing array antennas for radio imaging observations.The position accuracy of these array antennas affects the accuracy of time delay compensation and phase compensation, which in turn affects the synthetic image quality.Methods and results of combining RTK and Total Station to determine the initial geometric position of array antennas of MUSER-L, as well as those of MUSER-I and MUSER-H are introduced.
