| 成果简介 | NOVELTY - Invention relates to space geodesy, in particular to determination of navigation parameters of spacecraft orbits of satellite navigation system GLONASS using orbital method of space geodesy using results of observations of quasars. Technical result is achieved due to guaranteed reliability of determining the navigation parameters – coordinates and absolute speed of the object in the coordinated universal time of the Russian Federation – in the single state general-earth geodetic coordinate system, inertial geodetic coordinate system, coordinates of an astronomical-geodetic observatory with a radio telescope (AGO (RT)), coordinates of poles and irregularity of rotation of the Earth, coordinates of quasars. Disclosed method consists in the fact that the long-baseline radio interferometry (LBRI) system provides for the arrangement of two radio telescopes (RT) on Earth surface – AGO (RT) and onboard spacecraft – SC (RT) GLONASS, equipped with highly stable frequency standards. With the help of heterodynes, the received high-frequency radiation from a radio source does not come simultaneously, but with a certain time delay. As a result, two fundamental measured values are found: the time delay caused by the difference in distances to the phase centres of the SC (RT) and AGO (RT), which will vary due to a change in the angle between the base and the direction of the quasar, and the time delay of the Earth's rotation. USE - Cosmonautics; measuring. ADVANTAGE - High efficiency of navigation support of a single system of geodetic support with global geospatial information. 1 cl, 1 dwg |
