Announcement of development on an extensible “attitude angle detector gyro unit” and“attitude angle & true north*1 detector gyro unit 『Northfinder™』” using MEMS type
Sumitomo Precision Products Co., Ltd. has developed an extensible “Attitude angle detector gyro unit” and “Attitude angle& true north detector gyro unit 『Northfinder™』” by MEMS type that are used in railway vehicles
and aerospace equipment.
We are supplying sample from July 2022 and planning to start selling mass produced-productsaround December 2022.
As a result of many years of MEMS research and development, “Attitude angle detector gyrounit” and “Attitude angle & true north detector gyro unit 『Northfinder™』” are smaller,
tougher, and less expensive than those using RLGs or FOGs. These models are extensible toAttitude angle detector

accommodate an additional sensor module kind in order to support your needs.

“Attitude angle detector gyro unit”〔Description〕*1 True north is the North Pole direction aligned withlongitude, and magnetic north is misaligned withlongitude and varies with location and with time.

north detector gyrounit 『Northfinder™』

Attitude angle detector gyro unit can output attitude angle (roll/pitch angle) with high accuracy. It is possible to operate
in the “Motion Angle Measurement Mode” that outputs dynamic attitude angle, angular velocity and acceleration the sameas the pedigree. Also, the accuracy of attitude angle can be improved by inputting velocity.
〔Application〕
・Remote monitoring of track distortion in railways

Yaw angle
Roll angle

・Attitude control for industrial robots
・Attitude and motion measurement of other industrial equipment

Pitch angle“Attitude angle & true north detector gyro unit 『Northfinder™』”〔Description〕
Attitude angle & true north detector gyro unit 『Northfinder™』 can output real-time attitude and heading angles without
GPS and calculate attitude angle (roll/pitch angle) and azimuth angle (yaw angle) with high accuracy. It is possible tooperate in the “Static Angle Measurement Mode” that outputs static angle including azimuth angle without GPS. Also, thedynamic azimuth angle can be measured by combining the “Static Angle Measurement Mode” with the “Continuous Angle
Measurement Mode”, which uses the results of the static angle measurement as the initial value and improves the accuracy.
In addition, angular velocity and acceleration can be output in the same way as Attitude angle detector gyro unit, and theaccuracy of attitude angle can be improved by inputting velocity.
The angular velocity measurement error is even smaller than Attitude angle detector gyro unit.

〔Application〕
Attitude angle & true north detector gyro unit Northfinder™ is suitable for azimuth measurement in environment where
GPS cannot be used. It is also suitable for attitude measurement when you need a device with a smaller angular velocity
measurement error than Attitude angle detector gyro unit.
・Attitude control of air mobility
・Down hole surveying in the ground・High –precision output of ship attitude and motion
・Route mapping・Measurement of attitude and motion condition of underwater construction equipment, such as underwater backhoes
・Measurement of attitude and motion condition of underwater drones and other maritime vehicle
・Remote monitoring of track distortion in railways
Toward the promising future, we will continue to contribute to solving social issues such as promoting a post5G digital society and realizing a carbon-free society by providing products and services that utilize thestrengths of our technology.
