HARDWARE FOR TRANSMISSION OF NAVIGATION SIGNALS, METHOD OF TRANSMISSION OF NAVIGATION SIGNALS AND HARDWARE FOR OUTPUT OF LOCATION DATA

摘要

FIELD: physics, navigation.;SUBSTANCE: invention relates to navigation. Proposed system can output location data without deterioration in precision even inside the rooms with significant influence of attenuation at multipath propagation. Data output hardware (100) receives by reception antenna RX-ANT1 the locating signals from in-room transmitter (200) subjected to encoding with spectrum expansion with the help of various PRN-codes and transmitted via said antennas TX-ANT1 and TX-ANT2, respectively. Hardware (100) performs the search of PRN-codes of transmitted signals independently and in synchronism. In case one PRN-code is detected its synchronization circuit is used to detect another PRN-code of the other channel. On case detection is performed successfully in two channels, signal of one channel is selected to execute the location process.;EFFECT: higher stability of signals reception.;14 cl, 22 dwg
