Bearing calculator and error correction method
A bearing calculator provided with a geomagnetic sensor for detecting earth-geomagnetism and a control unit for calculating a geographical bearing based on detection values of the geomagnetic sensor. The control unit can execute offset error correction processing for correcting the offset error to the geomagnetic sensor based on a change in...

Navigation apparatus, operation control method, and mobile terminal apparatus
A navigation apparatus including a geomagnetic sensor that detects a geomagnetic field of the navigation apparatus, an orientation calculation unit that calculates an orientation of the navigation apparatus based on the detected geomagnetic field, a cradle detection unit that detects that the navigation apparatus is connected to a cradle, and outputs...

Geomagnetic sensor control device
A geomagnetic sensor control device includes an analog circuit unit that outputs a plurality of magnetic field measurement values corresponding to sensor output signals of a plurality of magnetic sensors, and a digital circuit unit that receives three-axis magnetic field measurement values from the analog circuit unit and that performs digital...

Atmospheric carbon dioxide mitigation
A regenerative process for the capture, sequester, and negative ionization of carbon dioxide for expulsion of the species within a geomagnetic polar region for subsequent treatment by high frequency electromagnetic radiation....

Receiver coil assembly for airborne geophysical surveying with noise mitigation
An airborne geophysical surveying system comprising a receiver coil assembly for towing by an aircraft, the receiver assembly including a receiver coil for sensing changes in a magnetic field component of a magnetic field, and a receiver coil orientation sensing system for sensing orientation changes of the receiver coil. A controller...

Alignment system
A magnetic hole finder arrangement having a test field detector including a GMR sensor and may having a test field detector including a first and second magnetic field detectors (which may be GMRs) arranged with respect to a hole location position, the detectors having magnetic axes each arranged transversely to a...
