Sensonor launches new high-accuracy tactical-grade IMU

The new high-accuracy tactical-grade STIM318 inertial measurement unit (IMU) from Sensonor provides greatly increased accelerometer performance to support demanding guidance and navigation applications, the company said. Its performance can in many applications competitively replace fiber-optic gyros (FOGs).

Offering improved system performance with respect to robustness, reliability, size, weight, power and cost, it is designed for use in autonomous machine control, UAV payloads, satellites, portable target acquisition systems, land navigations systems, turret stabilization, missile stability and navigation, and mortar aiming systems.

STIM318 is comprised of three highly accurate MEMS gyros, three high-stability accelerometers and three inclinometers. Its development took place in close cooperation with a global customer developing autonomous machine control for accurate contour guidance. The IMU is built on the established STIM design that is field proven in commercial and military applications.

An ITAR-free product, STIM318 is available in export controlled and non-export controlled versions. It is compatible with Sensonor’s STIM300 IMU, and can bring additional capability to applications already using STIM300. STIM318 is available from stock.

In addition to the performance increase, STIM318 comes with a new Bias Trim Offset (BTO) function. This allows the user to individually zero out any bias of all 9 axes. The bias offset can be stored in flash, and then recalled at next system startup.
