About the paper Full textAbstract
To solve problems of precision navigation and other applied tasks (for example, broadcasting precise time stamps over a transatmospheric communication channel, solving radio astronomy problems, processing and analyzing signals from space-based radar equipment, etc.), the measurement error caused by the tropospheric delay can be a very significant negative factor. On the territory of the East Siberian Branch of the FSUE VNIIFTRI, a modernized metrological complex for evaluating the energy characteristics of navigation satellite signals, primarily GLONASS system satellites, has been deployed and it has been successfully operating. The specified complex functionally includes a water vapor radiometer, which allows, among other things, to evaluate the attenuation of the navigation signal in the troposphere. To obtain the required accuracy of the water vapor radiometer, it is necessary to calibrate its high-frequency path using the method of “vertical cuts” of the atmosphere. During the operation of the water vapor radiometer, it was found that the features of its geographical location (elevation above the city), as well as its proximity to large water masses of the Irkutsk hydroelectric power station, impose restrictions on the azimuth of the calibration. During operation, a continuous comparison of the wet tropospheric delay is carried out, measured by a water vapor radiometer, and the values obtained as a result of global GNSS processing. The residuals obtained in this way allow monitoring the operating mode of the water vapor radiometer and the quality of measurements.
