Digital Ion Drift Meter (DIDM) instruments are designed to measure the velocity vectors of ambient ions at a spacecraft's location. Measurements of ion density and temperature are also provided. The local electrical field strength can be obtained via the relationship between electrical field, ion drift velocity and the measured magnetic field provided by on-board magnetometer.
