Drone-Enabled Magnetometer System Developed by Geometrics
weight carbon fiber shell with internal electronics including the
MFAM magnetic sensors, GPS, and IMU.
Operation in the field is simple. Survey details are programmed
into the user's UAS software. The MagArrow is turned on, and
once airborne, preprogrammed GPS waypoints carry the MagArrow in altitude stable survey lines. Once work is completed, data
from the MagArrow can be wirelessly downloaded to a computer.
Empowering geoscientists for over 50 years with its seismographs, magnetometers, and geoelectric instruments, Geometrics
now has developed its first ever drone-enabled magnetometer
that opens new capabilities in geo-surveys. The MagArrow's sleek
housing holds the company's MFAM (Micro-fabricated Atomic
Magnetometer) module, a miniature magnetometer capable of
highly precise measurements in an extremely lightweight and tiny
package.
"MagArrow is setting a new standard for UAS
(Unmanned Aerial Systems) magnetic surveys
and the MFAM module is our most groundbreaking magnetometer yet," says Mark Prouty,
CEO of Geometrics, which is based in San
Jose, California.
The MagArrow is engineered to simplify
surveys that are difficult due to the various
limitations of pilot-on-board surveys and ground
surveys. It consists of an aerodynamic, light-

The magnetometer is based on advancements in cesium-vapor
magnetometer technology that enabled a 10-fold reduction in
sensor size with an increase in performance. Recent advances in
laser technology and MEMS fabrication techniques, supported by
the Defense Advanced Research Projects Agency (DARPA) and
the Strategic Environmental Research and Development Program
(SERDP), have led to miniaturized
components for atomic clocks and
magnetometers. Using its experience
in building field-rugged magnetometers, Geometrics applied the advancements to develop its MFAM sensor
products.
Its dual-sensor module has two sensors that allow for individual or gradient measurements. They can
be reconfigured to achieve dead-zone free operation anywhere
in the world and can accommodate heading error compensation.
Geometrics offers developer kits using this dual-sensor module.
