NanoMagSat

NanoMagSat is a future satellite constellation under development by the European Space Agency (ESA) for the study of Earth's magnetic field and ionosphere. The mission will consist of three 16U CubeSats named Alpha, Bravo, and Charlie in low-Earth orbit at an altitude of 545 km, two at an inclination of 60° and one in polar orbit. Each satellite will be equipped with a long deployable boom carrying an absolute magnetometer at its end and a high-frequency magnetometer positioned midway along the boom. The body of each satellite will carry a multi-needle Langmuir Probe and two GNSS receivers. The satellites are being built by the UK-based company Open Cosmos and their first launch is expected in late 2027.
