2. International Real-time Magnetic Observatory Network

   en.wikipedia.org/wiki/International_Real-time...

   The International Real-time Magnetic Observatory Network (INTERMAGNET) is a world-wide consortium of institutes operating ground-based magnetometers recording the absolute level of the Earth's time-varying magnetic field, [2] [3] [4] to an agreed set of standards. INTERMAGNET has its roots in discussions held at the Workshop on Magnetic ...

   en.wikipedia.org/wiki/Swarm_(spacecraft)

   Swarm is a European Space Agency (ESA) mission to study the Earth's magnetic field.High-precision and high-resolution measurements of the strength, direction and variations of the Earth's magnetic field, complemented by precise navigation, accelerometer and electric field measurements, will provide data for modelling the geomagnetic field and its interaction with other physical aspects of the ...

4. Spacecraft attitude determination and control - Wikipedia

   en.wikipedia.org/wiki/Spacecraft_attitude...

   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. If spacecraft position is known ...

   We now know that every day, magnetic north traces an elliptical path of about 75 miles (120 kilometers). Since its discovery, magnetic north has drifted away from Canada and toward Russia.

   Earth’s outer core is made up of mostly molten iron, a liquid metal. Unpredictable changes in the way it flows cause the magnetic field around the Earth to shift, which then causes the magnetic ...

7. Spacecraft magnetometer - Wikipedia

   en.wikipedia.org/wiki/Spacecraft_magnetometer

   Explorer 6 (1959) used a search coil magnetometer to measure the gross magnetic field of the Earth and vector fluxgate., [27] however because of induced magnetism in the space craft the fluxgate sensor became saturated and did not send data. Future missions would attempt to place magnetometers further away from the space craft.
