An alternative is to use a 3-axis fluxgate magnetometer to provide a 3D flux vector, with the magnetic heading derived from the flux on a plane perpendicular to gravity, thus providing immunity from pitching and rolling. Fluxgate compasses and gyrocompasses complement one another nicely.
A two axis magnetometer was mounted to the ATS-1 (Applications Technology Satellite). [20] One sensor was on a 15 cm boom and the other on the spacecraft's spin axis (Spin stabilized satellite). The Sun was used to sense the position of the boom mounted device, and triaxial vector measurements could be calculated.
The magnetic field induces a sine wave in a rotating coil. The amplitude of the signal is proportional to the strength of the field, provided it is uniform, and to the sine of the angle between the rotation axis of the coil and the field lines. This type of magnetometer is obsolete.
A MEMS magnetic field sensor is a small-scale microelectromechanical systems (MEMS) device for detecting and measuring magnetic fields (magnetometer). Many of these operate by detecting effects of the Lorentz force : a change in voltage or resonant frequency may be measured electronically, or a mechanical displacement may be measured optically.
A magnetometer is a device that senses magnetic field strength and, when used in a three-axis triad, magnetic field direction. As a spacecraft navigational aid, sensed field strength and direction is compared to a map of Earth's magnetic field stored in the memory of an on-board or ground-based guidance computer.
An attitude and heading reference system (AHRS) consists of sensors on three axes that provide attitude information for aircraft, including roll, pitch, and yaw. These are sometimes referred to as MARG (Magnetic, Angular Rate, and Gravity) [ 1 ] sensors and consist of either solid-state or microelectromechanical systems (MEMS) gyroscopes ...
Cross axis sensitivity: parasitic measurement induced by solicitation along an axis orthogonal to sensor axis; Noise: dependent on desired dynamic performance; Environment sensitivity: primarily sensitivity to thermal gradients and accelerations; All these errors depend on various physical phenomena specific to each sensor technology.
A modern military compass, with included sight device for aligning. A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north.
