Find out more about other motion and navigation sensors

Inertial Navigation Systems (INS) and Inertial Measurement Units (IMUs) are key technologies used to determine the position, orientation, and motion of an object without relying on external signals. An IMU is a sensor that measures acceleration and angular rate using accelerometers and gyroscopes. When combined with algorithms and, optionally, GNSS data, an INS uses this information to calculate the object’s trajectory in real time. These systems are essential for navigation in environments where GNSS is unavailable or unreliable, supporting applications in aerospace, autonomous vehicles, precision guided munitions, marine operations, and more.
