FIELD: aircraft engineering.
SUBSTANCE: navigation parameters of spacecraft orbit are measured with the help of ground measuring stations. Said measured parameters are transmitted to processing center. Said measured parameters are converted, time moments of said measurements are recorded as measurements program while navigation parameter magnitudes measured by ground stations are used as measurements results. Converted navigation parameters are preprocessed to define orbit parameters by converted said parameters and vector of initial approximation of target parameters.
EFFECT: higher reliability of definition.
