Time–space system in real time is a synthetic coherent measuring system to measure state vector parameters in all physical fields including gravitation, wave and magnetic fields in real time on the global, regional, local and user's measuring levels. It comprises a radio measuring system and a geophysical subsystem. Radio measuring system is a global radio telescope with unfilled aperture, equivalent to synthetic phase array with central synchronizer PVS RV. Radio system is a geometric frame and synchronized atomic scale of time and frequencies for geophysical subsystem. The geophysical subsystem is intended for defining parameters of gravitation and wave fields on the Earth's surface, in space, on sea, and in boreholes, installed in unmovable, flying or moving objects. On all levels of PVS RV functioning, the elements of radio system and geophysical subsystem are linked on the level of mechanical and electrical interface. Functional purpose of PVS RV is the creation, maintenance and extension of the base global network to measure in real time the parameters of physical and wave fields and to determine their sources including gravitational, magnetic and electrical fields; base surface-space network of high-precision frequency-time synchronization on the basis of coupled scales of universal time (UT1), scale of atomic coordinated time (UTC) and global scale of atomic time PVS RV of the highest precision. Contribution of radio system PVS RV: data on the global scale of time and frequency (global time-frequency synchronization and transfer of time and frequency scales); single surface-space scale of time and frequency; geodetic coordinates of stations and velocity; stable and absolute global distance scale; base geometric framework for geophysical subsystem; International Celestial Reference Frame (ICRF), coordinates of extragalactic sources, complete set of the Earth orientation parameters (EOP): pole coordinates; UT1/LOD (international designation: Universal time, day duration), nutation, atmospheric data (troposphere and ionosphere). Contribution of geophysical sub-system: geophysical research, seismic prospecting (land, sea), gravimetric prospecting (land, sea, air), seismology (record of earthquakes, landslides, avalanches); meteorology; navigation, motor transport, aircraft and rocket-borne equipment; devices to determine aircraft orientation in the Earth's gravitation field; aiming at surface, subsurface, water, and underwater moving objects and aircrafts to protect buildings, airports, frontiers; civil defense: earthquake warning devices, including individual devices, and alarm system.
