Magnetics Business & Technology - January/February 2025 - 13

FEATURE ARTICLE
The device is about the size of a carton of milk. The coin is from MagQuest Challenge.
Confirming the durability and accuracy of these devices would
also pave the way for additional space-based applications
ranging from attitude control and guiding rovers on the surface
of other planets, to mapping minerals under the surface of the
moon and an array of other possibilities. The sensors can easily
be mounted on small cube satellites and launched into orbit at
a nominal cost, making precise, detailed data about the earth's
magnetics and geophysics easily accessible to those stakeholders
who require it for planning operations, mapping logistics or
other relevant applications.
Minerals exploration with Silicon Microgravity
The partnership with Silicon Microgravity, a disruptive technology
company developing innovative inertial and gravity sensors that
was spun out of the University of Cambridge's Nanoscience Centre,
came in March 2024. The project will see the development
of a drone-based system of sensors combining
magnetics and gravimetry to accelerate the location
and analysis of underground mineral deposits for
the mining industry.
" It is of paramount importance for SBQuantum to
both develop international partnerships as well as
diversify our sensing stack to improve hit rates for
mineral drilling. This project with Silicon Microgravity
accomplishes both. We would like to thank IRAP
for providing part of the funding to deploy quantum
magnetometers in the field, on airborne platforms,
and we're eagerly looking forward to deploying this
hardware in the field " said Roy-Guay.
The Science
Magnetometry is one of the oldest measurement
technologies, so what are nitrogen vacancy diamonds?
NV centers occur when the carbon lattice
of a diamond is interrupted by a nitrogen atom and
an adjacent void. This can occur naturally, but more
often is specially engineered. The introduction of
the nitrogen atom frees a single pair of electrons
from the diamond's chemical structure which allows
SBQuantum to derive magnetic information from
their spin.
SBQuantum's diamond magnetometer leverages
quantum properties to reduce drifts such as those
induced by temperature constraints which can
distort readings from today's classical technologies.
The diamond crystal contains four sensing axes
in a very small volume at the atomic scale, and

Cancellation
the amplitude and direction of its magnetic field measurements
provides high accuracy with no blind spots. The device's use of
quantum effects also provides a greater accuracy than existing
technologies. By applying a green laser and microwaves to the
diamond, a red glow is generated which translates directly to the
magnetic field vector measurements at the basis of the World
Magnetic Model.
The company's proprietary algorithms allow it to capitalize on
the vectorial data and maximize the information gathered on
metallic or magnetic objects. Not only can an object's presence
be observed, its size, orientation, material and distance from the
sensor can be determined. An advantage of the compact sensors
is that they fit easily onto autonomous platforms such as drones,
rovers or autonomous underwater vehicles. For more info, see
