RADIONAVIGATION MULTI-POSITION DIFFERENTIAL DISTANCE SYSTEM Russian patent published in 2021 - IPC G01S3/46 G01S7/00 G01C21/00 G06G7/78 

FIELD: radionavigation.

SUBSTANCE: invention relates to radionavigation systems for determining location or obtaining information related to location for navigation purposes by means of propagation properties of radio waves and properties of surfaces (lines) of position. The system includes of the equipment of the basic navigation post, the slave posts and the consumer. The equipment of the basic navigation post includes a device for entering the code and coordinates of the post, a modulator, a transmitter and an antenna. The equipment of the slave posts includes an antenna, a decoupling device, a radio frequency amplifier, a decoder, a device for entering the code and coordinates of the post, a modulator and a transmitter. Information consumer equipment includes antenna, receiver, decoder, RAM codes and coordinates of navigation posts. The system additionally contains a device for forming a navigation field with time division of channels, a device taking into account the total number of navigation posts.

EFFECT: technical result consists in creating a mobile radionavigation multi-position differential distance system capable of duplicating signals from global navigation systems when they are lost on limited areas of the earth's surface.
