STIM300 Inertial Measurement Unit


STIM300 is a small, tactical grade, low weight, high performance non-GPS aided Inertial Measurement Unit (IMU). It contains 3 highly accurate MEMS gyros, 3 high stability accelerometers and 3 inclinometers. The IMU is factory calibrated and compensated over its temperature operating range.


STIM300 is a cost effective ITAR free solution for systems that only had FOG's as an alternative when reaching for the performance level of that STIM300 can offer.

Application areas

The STIM300 IMU is well suited for stabilization, guidance and navigation applications in Industrial, Aerospace and Defense markets. It is a crucial building block for inertial navigation systems in UAVs, AUVs, AGVs, UGVs and ROVs.


STIM300 is also used for camera turret stabilization and for use in various handheld devices that require a small IMU to secure operations during GPS outage.

Each axis is factory-calibrated for bias, sensitivity and compensated for temperature effects to provide high-accuracy measurements. The unit runs off a single +5V supply and communicates through a standard RS422 interface.
For advanced users, STIM300 may be put in Service Mode. In this mode all the configuration parameters can be intermediately or permanently changed by overwriting the current settings in the flash memory. Service Mode also provides the ability to perform single measurements, perform diagnostics and obtain a higher detail in the status byte.
The STIM evaluation tool offer easy measurement and configuration access for STIM gyro modules and IMUs. The tool support data sampling at alternative rates, graphical data presentation and data log to file for up to two gyro modules/ IMUs in parallel. RS422 interface for PCI, necessary cabling and PC software is included in the evaluation tool.
