Multi-source self-calibration: Unveiling the microJy population of compact radio sources [PDF]
, 2016 Context. Very Long Baseline Interferometry (VLBI) data are extremely sensitive to the phase stability of the VLBI array. This is especially important when we reach {\mu}Jy r.m.s. sensitivities.

The LOFAR Long-Baseline Calibrator Survey Classification
Latvian Journal of Physics and Technical Sciences, 2020 Abstract Data manipulation of the LOFAR Long-Baseline Calibrator Survey (LBCS) and the Westerbork Northern Sky Survey (WENSS) catalogues are carried out in the present study. The aim of the study is to make calibrator classification statistics plots and estimations for further observations and upcoming stations.

Precise Determination of Calibration Baseline Distances
Journal of Surveying Engineering, 2019 Some errors that affect the accuracy of electronic distance measurement (EDM) instruments can be determined in a laboratory, but most are detectable and measurable only on a calibration baseline on which distances are precisely determined. In this paper, precise distance determination is presented on the calibration baseline of the Faculty of Geodesy ...

Calibration and Emitters Selection Method of Interferometer Based on Single or Double Emitters [PDF]
Hangkong bingqiThe traditional method of joint calibration of fixed baseline interferometer with multiple errors requires more than three calibration emitters to achieve real-time calibration of the interferometer in orbit, but the performance of the traditional method
