COHERENT TRANSPONDER OF PHASE SYNCHRONIZATION Russian patent published in 2008 - IPC G01C21/24 

FIELD: invention refers to the field of astronomical and astrophysical explorations.

SUBSTANCE: coherent transponder of phase synchronization has a radio receiving set, a radio transmitting set, an airborne standard of frequency (H-maser) and also a logic and commutation block. The radio transmitting so as the radio receiving set consists of two half-sets. The radio receiving set has a radio receiver module of the amplifier of a very high frequency, a preliminary amplifier of intermediate frequencies, a block of phase automatic adjustment of the frequency, the amplifier of the reference signal 2▾ and the secondary source of feeding.▾- nominal frequency. The coherent transponder of the phase synchronization provides transformation of the input signal in diapason 961▾ into an answer signal in the diapason 1120▾ used for synchronization of the airborne thermostating controlled generator. For reducing the drift of the phase of the answer signal the system of transformations of frequencies is built on the principle of complete matching of tracts of multiplying of the radio transmitting set and the heterodynes of the radio receiving set.

EFFECT: phase synchronization of the airborne scientific cosmic apparatus on a weak signal on the whole extension of the high-apogeal orbit of the flight.
