DIGITAL MAGNETIC COMPASS SYSTEM WITH ADJUSTMENT Russian patent published in 2022 - IPC G01C17/00 

FIELD: navigation instrument making.

SUBSTANCE: invention relates to navigation instrument making, namely to magnetic vessel compasses; it can be used to adjust readings of a magnetic compass, when passing set routes with a remote transmission of an image of a compass course scale, for example, to a steersman post and other consumers. A digital magnetic compass system contains a digital magnetic compass (hereinafter – DMC), a receiver for satellite navigation signals GPS/GLONASS, a buffer amplifier, an LCD identifier, a repeater, a power source, a converter, and a computer. At the same time, the receiver for GPS/GLONASS signals is connected with an output to the first information input of DMC, a DMC output is connected with the first signal bus to an input of the buffer amplifier and an input of the converter, an output of which is connected to a computer input. An output of the buffer amplifier is connected with the second signal bus to the repeater, and with the third signal bus to the LCD identifier, and with the fourth bus to other consumers of compass course information in a pilot house. In this case, DMC contains a microcontroller (hereinafter – MC), a positioning module, and a magnetic module made with the possibility of measuring the Earth’s magnetic field, wherein the first information input of DMC is connected through MC with a bidirectional bus to the first input of the positioning module, to the second input of which an output of the magnetic module is connected, and an input of which is connected to the second information input of DMC.

EFFECT: increase in the accuracy of maintaining set courses along the entire route.
