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, comprising:

a magnetic compass,

a magnetometer or optical reader for obtaining the signal from the magnetic compass, and

a commutation system, said commutation system further comprising;

integrated software in a chip, and

a circuit with an input for the signal from the magnetic compass and another input for a signal from a satellite compass or gyroscope,

wherein the magnetic compass comprises;

a transparent sphere or cylinder having a liquid derived from petroleum therein,

a disk comprising a polyester, silicon or gelatin disk and floating in the liquid,

a compass rose incorporated in the disk and

a magnet on the compass rose, and

wherein, the software is capable of contrasting the input signals so as to prepare a deviation chart in real time.

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

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