AUTONOMOUS VECTOR MAGNETOMETER 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 general view is shown above: front view - left and rear view - right. 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.
