Low Power Magnetometer

The LPMs operate unmanned all year round, including the long winter, when continuous periods of darkness and temperatures as low as −80°C prohibit human intervention. This has been made possible by new technology which allows the magnetometers to use very little power and survive the winter on solar power stored during the summer. The network measures magnetic fluctuations over a wide area. The data can be used to produce maps of space weather in the region around the earth where satellites orbit.
