Abstract

The invention relates to an integral magnetic compass for obtaining deviations in real time, formed by a transparent sphere or cylinder (2), incorporating therein, in a hydrocarbon liquid (3), a polyester or silicon disk (4) to which the rose (5) and the magnet (6) are fitted, being associated with a commutation system formed by integrated software in a device or chip (7), the circuit of which has two inputs: an input (8) to the signal obtained from the magnetic compass (1) itself, obtained by means of a magnetometer (9) or optical reader (10) in association therewith, and another input (11) to the signal from the satellite compass (12) or from the gyroscopic compass (13), and said circuit having an output (14) to a display (15) for viewing and storage of the data for the corresponding deviations, thus obtaining the deviation chart for the magnetic needle in real time, said output being also applicable to the automatic pilot (16).

Claims

1. Integral compass for obtaining deviations in real time, applicable in vessels, formed by a magnetic compass, a magnetometer or optical reader for obtaining the signal from the magnetic compass and a commutation system, wherein the commutation system is formed by integrated software in a chip and a circuit with two inputs, an input of the signal of the magnetic compass and another input of the signal of a satellite compass or gyroscope, characterized in that the compass is formed by a transparent sphere or cylinder, incorporating therein a liquid derived from petroleum, a polyester, silicon or gelatin disk floating in the liquid, a rose incorporated in the disk and a magnet, and in that the software is capable of contrasting the input signals and thus preparing a deviation chart in real time.

2. Integral compass according to claim 1, comprising a display for viewing of the deviation chart.

3. Integral compass according to claim 1, further comprising means for storing the deviation chart.
