FIELD: measurement equipment.
SUBSTANCE: invention relates to the field of radio-navigation and is designed for accurate detection of spatial coordinates, components of a speed vector and angular alignment of various consumers by signals from satellite radio-navigation systems (SRNS). For this purpose the digital receiver comprises antennas, a 3-channel radio-receiving unit, 12 identical multiple-channel correlators, 12 identical units for assessment of parameters of received navigation signals, a calculator, a unit for generation of reference signals from a multi-channel correlator. Each of 12 units for assessment of parameters of received navigation signals comprises a frequency discriminator, smoothening filters, delay discriminators, discriminators of phase difference, subtraction units, a unit for dedication of digital information, a unit for dedication of ephemerids. Each of phase difference discriminators comprises multipliers, summators, subtraction units, a multiplier by two, a unit of sine calculation, a unit of cosine calculation.
EFFECT: increased noise immunity and accuracy of navigation support to a consumer due to usage of combined coherent-incoherent processing of signals.
