IMU
is a self-contained system which is used to measure angular and
linear motion with a triad of accelerometers and triad of gyroscopes.
An IMU can either be strap down or gimballed, thereby outputting the
integrating quantities of acceleration and angular velocity in the
sensor or body frame. The rising advancement of global lifestyle has
encouraged the use of equipment with better ergonomics. This is
generally supported by the use of motion sensing technology which
includes inertial sensors. IMUs are used majorly for applications
like industrial, marine and military, for effective control,
stabilization, navigation, guidance, and surveying.
The
demand across these applications is majorly driven by ability of IMUs
to function in extreme environmental conditions, including heavy
buildings, tunnels, and underwater. These IMUs can also be used in
places with no or very limited GPS access. The end products of IMU
include Attitude and Heading Reference System (AHRS) and Inertial
Navigation System (INS), which are used as a major component in ships
and submarine, aircrafts, Unmanned Aerial Vehicle.(UAV), Remotely
Operated Vehicle (ROV), Autonomous Underwater Vehicle (AUV),
spaceships, high-end automotive and guided missiles, among others.
The
growing advancement in Micro-electromechanical systems (MEMS) is one
of the most prominent factors which are bolstering the demand of
IMUs. This is generally triggered by the advancements across digital
signal processing space. Also, the market demand is fuelled by the
increasing need for better navigation techniques and growing
manufacturing of aircrafts worldwide. The market growth is also
driven by improved product solutions such as the small quartz-based
MEMs, which are seeing higher adoption being economical and energy
efficient as compared to the traditional IMUs. These new MEMs IMUs
are considered to be very efficient in underwater applications due to
their ability to withstand high vibration and temperature conditions
which allows these systems to function for much longer period.
However, the market growth is restricted by the greater operational
complexity with high maintenance and operational cost.
The
global IMU market has been segmented on the basis of components,
platforms, gyro technology, applications and geographical regions. On
the basis of various components, the market is classified into
gyroscope, magnetometer, and accelerometer. Based on different
platforms where these IMUs are implemented, the market has been
divided into airborne, land and naval (water). Based on various gyro
technologies, the market is classified into Ring Laser Gyro (RLG),
Fiber Optic Gyro (FOG), Hemispherical Resonator Gyro (HRG),
Micro-electromechanical systems (MEMS), and vibrating gyro among
others. In terms of applications, the global IMU market has been
classified into control and stabilization, measurement and testing,
navigation and correction, unmanned control, payloads, underwater
systems, mobile mapping, automotive testing and bore industry. Based
on various geographical locations, the market is segmented into North
America, Europe, Asia Pacific, Middle East and Africa, and Latin
America. The global IMU market in North America is mainly driven by
the high levels of investment done by the U.S. government in these
advanced technologies which is supporting the military prioritization
on IMU.
Some
of the prominent players in the global IMU market include Honeywell
International Inc., Thales Group, Northrop Grumman Corporation, Kvh
Industries, Inc., Moog, Inc., Rockwell Collins Inc., Fairchild
Semiconductor, Analog Devices, Inc., Xsens, Sensonor AS, and
VectorNav Technologies, LLC, among others.
