NEAR-FIELD NAVIGATION SYSTEM Russian patent published in 2016 - IPC G01C21/00 

FIELD: navigation.

SUBSTANCE: invention relates to navigation and can be used in near-field navigation systems. For this purpose the system is equipped with base segment (3) arranged on basic structure (12), herewith base segment (3) contains at least four transmitters (30, 32, 34, 36), and every transmitter is provided with base antenna (31, 33, 35, 37), and herewith base antennae (31, 33, 35, 37) are located at known distances from each other, user segment (4) located on user structure (20), herewith user segment (4) contains at least one receiver (40), at least one user antenna (41, 42, 43) connected to receiver (40), and processing module (44) connected to receiver (40), herewith receiver (40) and each of transmitters (30, 32, 34, 36) form together modules for measuring distance, and processing module (44) is made with the possibility of calculating data on relative 3D position of user structure (20) with respect to basic structure (12) on the basis of data on the distance received from the modules of measuring distance.

EFFECT: technical result is improvement of accuracy of determining coordinates.
