LEMI-026


An autonomous fluxgate magnetometer LEMI-026 is intended for precise 3-component measurements of Earth magnetic field both in motion and as a reference base. Its external view is given above in housing (right) and without (left). It may be used for autonomous measurements using moving carriers (drones) or being included in sea/land station. There are two-component tiltmeter inside and GPS antenna allowing obtaining precise measurement timing, magnetometer coordinates and attitude during movement. These data are stored in the SD memory card.
