An Inertial Measurement Unit (IMU) is a device that is made up of gyroscopes and accelerometers to measure and report angular rate and report specific force respectively. The specific gravity and the angular rate associated with an object are two of the key parameters that are measured by a defense inertial measurement unit. A magnetometer is noted to be an optional component within this setup, it is used for the measurement of a magnetic field surrounding the system. An apparatus known as an Attitude and Heading Reference Systems (ARHS) is created by integrating a magnetometer into a Defense Inertial Unit which filters algorithms to determine orientation information results in a device.
The overall functioning of an inertial measurement unit suggests that only measurements along or around one axis can be sensed by a single inertial sensor. Three separate inertial sensors must be mounted together as an orthogonal cluster known as a triad to produce a three-dimensional solution. Since the sensors may provide one measurement along each of the three axes, this group of inertial sensors positioned in a triad is known as a 3-axis inertial sensor. Similar to this, an inertial system with a 3-axis gyroscope and 3-axis accelerometer is known as a 6-axis system since it offers two separate measures along each of the three axes for a total of six measurements.
Major factors driving the growth of the market
The increased proliferation of Advanced Driver Assistance Systems (ADAS), as well as autonomous vehicles within the commercial as well as the defense industry, is poised to drive the growth associated with this Inertial Measurement Units market. The Inertial Measurement Unit can be used to showcase the precise location of the automotive system in real-time thus bolstering the demand for MEMS-based IMU technology.
Trends influencing the growth of the market
The increased application of gyroscopes within the defense sector is one of the main factors that propel the growth associated with the defense inertial measurement units market. The device is used to measure the exact velocity as well as to stabilize the angular velocity. The overall growth dynamics are governed by the increased demand for MEMS-based technology that allows the end-users to obtain precise information about the surrounding area within the commercial automotive as well as the defense sector.
Collins Aerospace, a US-based company, has a lot of expertise in the creation of MEMS and inertial sensor technology. The company has seen substantial expansion over the past ten years and is increasingly focusing on the aerospace and defense industries. A recent contract for USAF F-16, B-2 sustainment for USD 34 million was recently awarded to the business in February 2021.
Another key player within the Defense Inertial Measurement Unit market is noted to be Safran. The organization was recorded to have launched Geonyx M in June 2021. This system was created for and in collaboration with marine commandos. Geonyx M benefits from technology and input from other Safran Electronics & Defense product lines, such as Black-Onyx (surface vessels), Argonyx (surface vessels), and Geonyx (land vehicles) (submarines). Because of its history, it may give a genuine advancement in terms of performance, dependability, accuracy, and robustness.
Increased research-based investment within the defense inertial measurement unit is poised to drive the growth associated with this market. The increased market penetration of unmanned systems is another factor that is poised to drive the growth associated with defense inertial measurement units. Presently, it is noted that IMUs are widely used in AGVs, Unmanned Aerial Vehicles (UAVs), and other robots that need to determine their position in space as well as altitude.
Collaborative Robot Research is another segment that is gaining popularity within the research sector for the application of inertial measurement units. The studies concentrate on how human workers who work with collaborative robots are positioned. To achieve secure human-robot collaboration, the placement of human workers is necessary. The positioning of the human workers is to be determined using vision and ranging sensors. While the altitude, as well as the position associated with the operator, can be determined using IMU. The motion capture system based on IMUs can track the movement of the operator’s entire body, making it more suitable for human-robot collaboration than the earlier method, which often only records the operator’s general location and direction. The IMU is additionally utilized in some visual systems (like SLAM) for data fusion and complementation.
