The article deals with a promising method of GNSS-reflectometry which is currently used to solve a range of different problems in oceanology, climatology, hydrography, geophysics, glaciology, hydrometry, and many other related Earth sciences. It is shown that the accuracy of the GNSS-reflectometry method using only one receiver is estimated to be several centimetres and depends on reflecting surfaces. According to preliminary results, the accuracy of the GNSS-reflectometry method using a single receiver lies within a few centimetres and depends not only on reflecting surfaces, but also on the choice of a satellite to analyse. To eliminate any erroneous results in determining the distance to the reflecting surface, it is suggested to analyse a larger number of satellites located at elevation from 5 to 25 degrees.
