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.
Magnetic Data Acquisition System (abbr. MAGDAS) is a system of 50 realtime magnetometers that are being deployed by Kyushu Sangyo University of Fukuoka, Japan, as part of Japan's leading contribution to International Heliophysical Year of the United Nations.
A SQUID (superconducting quantum interference device) is a very sensitive magnetometer used to measure extremely weak magnetic fields, based on superconducting loops containing Josephson junctions. SQUIDs are sensitive enough to measure fields as low as 5×10 −18 T with a few days of averaged measurements. [ 1 ]
The main science instrument sets are the Sun-observing Plasma Magnetometer (PlasMag) and the Earth-observing NIST Advanced Radiometer (NISTAR) and Earth Polychromatic Imaging Camera (EPIC). DSCOVR has two deployable solar arrays, a propulsion module, boom, and antenna. [20] The propulsion module had 145 kg of N 2 H 4 propellant. [21]
Schematic of Earth's magnetosphere. Canadian Geospace Monitoring (CGSM) is a Canadian space science program that was initiated in 2005. CGSM is funded primarily by the Canadian Space Agency, and consists of networks of imagers, meridian scanning photometers, riometers, magnetometers, digital ionosondes, and High Frequency SuperDARN radars.
MAD rear boom on P-3C The SH-60B Seahawk helicopter carries a yellow and red towed MAD array known as a "MAD bird", seen on the aft fuselage. A magnetic anomaly detector (MAD) is an instrument used to detect minute variations in the Earth's magnetic field. [1]
In general, ICEMAG data would have combined synergistically with other data sets to improve knowledge of interior properties and exosphere activity. The instrument was put under review in the summer of 2018 due to out of control costs. By March 6, 2019, the instrument was cancelled in favor of finding a more affordable, less complex replacement.
This can result from the design of the magnetometer to the way the magnetometer interacts with the spacecraft, radiation from the Sun, resonances, etc. Using completely different design is a way to measure which readings are the result of natural magnetic fields and the sum of magnetic fields altered by spacecraft systems.
