The MagArrow
The MagArrow is a laser pumped, cesium vapor (Cs133 non-radioactive) total field scalar magnetometer.
The system’s light weight makes it ideal for use with unmanned aerial systems (UAS) that can support a
payload of 1kg or greater. Within its aerodynamic carbon fiber housing, the MagArrow contains:

MFAM miniature magnetometer

GPS

SD Memory Card

USB Drive

Wireless Connection Point

Gyro, Compass, and Accelerometer
The MFAM miniature magnetometer comprises of two high-performance cesium sensors attached to
one sensor driver module. The two sensors are used together in order to eliminate the dead zone and
reduce heading error. Its small weight, low power, and 1000Hz sampling rate make the MFAM a
revolutionary sensor in the geophysical market.
One MFAM Sensor
The 1PPS pulse from the GPS synchronizes the sampling rate to ensure 1000 samples are recorded per
second. The SD memory card is 32Gbytes and never needs to be removed since data is downloaded via
WiFi. The USB drive holds the latest MagArrow firmware and can be used for fast field upgrades. The
