Annotation: In this paper corrections to the measured values of the tropospheric delay of a navigational signal are calculated using the refractive index height profiles obtained as a result of upper-air sounding of the atmosphere in the southeastern part of the Sea of Okhotsk, as well as two model profiles. It is shown that the three-element model is more consistent with the experimental profiles than the exponential one. Values of the tropospheric delay RMS for these two models are given.

Keywords: navigation signal delay, troposphere, refraction coefficient, mean-square error
