Measurement of antenna parameters by signals from space satellites of the GLONASS and Navstar navigation systems

We present the results of experiments on measuring the antenna pattern and alignment of the RT-14 and RT-15 radio telescopes located in the radioastronomy observatories of the Radiophysical Research Institute of Nizhny Novgorod by signals from space satellites of the GLONASS and Navstar navigation systems. The efficiency of using signals of the navigation satellites to measure a number of parameters of the antenna systems is analyzed.
