Celestial mechanics interpretation of radio measurements of slant range and radial velocity

Celestial mechanics interpretation is defined as calculation parameters of spacecraft motion from observed quantities obtained at the tracking stations. The range and range rate models are considered. Particular attention has been paid to the Doppler effect. One-way, two-way and three-way Doppler measurements are investigated. Results are given for media corrections for the computed values of the observables. The ionospheric and tropospheric errors of measurements have been studied.
