The method of complex measurement, in the real time mode, of parameters of the spatio-temporal system comprising the hardware complex of the radio-interferometric network with superlong baselines (RNSB-SYSTEM), which hardware complex includes three or more radio-telescopes connected with each other by fast-track communication channels and aimed at extragalactic objects, and transmits the measured parameters to the user, which method consists in performance of the following operations of taking measurements of the basic (fundamental) observable values directly during observation of extragalactic sources; transmitting the data to the processing centre; registering the results of processing of the data in the form of sequence of the discrete current values of OSN correlative functions appearing each half the interval of an individual observation, wherein each observation interval is optimized by two parameters: admissible statistical lapse (error) of measurements of the basic (fundamental) observable values and the own interval in accordance with the Kotelnikov/Nyquist fluctuations of the propagation delay in a medium; instrumental fluctuations in radio-telescopes of the RNSB-SYSTEM wherein the corrective action of all instrumental errors is performed without additional time consumption due to the procedures fulfilled in parallel (simultaneously) with measuring the OSN correlative functions, the corrective corrections of the fundamental observable values in the form of differences between the true and pre-computed model values are used in radio-telescopes of the RNSB-SYSTEM in the feedback circuits for correction of the position of all radio-telescopes in relation to the position of the extragalactic objects and for minimization of errors in the measurements, the errors in time and frequency synchronization are transmitted from the processing centre to each radio-telescope in the form of corrections to the values of the reference frequency and the values of the time signal, these errors in measurements are simultaneously used for shaping the integrated signal intended to the user, from all radio-telescopes of the RNSB-SYSTEM, the user represents (forms) a two-element compound-interferometer with the synchronized RNSB-SYSTEM operating in the mode of the phased grid (array) of the global size with the total surface equal to the sum of the effective surfaces of all radio-telescopes composing the RNSB-SYSTEM.
