GLONASS RECEIVER Russian patent published in 2013 - IPC G01S19/23 

FIELD: radio engineering, communication.

SUBSTANCE: GLONASS receiver includes: a signal receiving unit (11) for receiving a plurality of signals, having different frequencies, from a plurality of artificial satellites, respectively; a temperature detector (33); a memory device (14) for storing group delay characteristics of each signal in the signal receiving unit (11) in form of group delay characteristic data and for preliminary storage of the temperature dependence for group delay of each signal in the signal receiving unit (11) in form of temperature dependence data; and a position computer (15) for correcting reception time of each signal using group delay characteristic data, for correcting the reception time of each signal based on temperature and temperature dependence data and for calculating the current position in accordance with the corrected reception time.

EFFECT: high accuracy of positioning a GLONASS receiver by reducing the effect of temperature without complicating performance, reducing efficiency of the manufacturing process, complicating the circuit, increasing dimensions and reducing sensitivity.
