STIM318 IMU
Non-GPS Aided
View all Inertial Measurement Units.
STIM318 is a small, tactical grade, low weight, high performance non-GPS aided Inertial Measurement Unit (IMU) with greatly improved accelerometer performance. It contains 3 highly accurate MEMS gyros, 3 ultra-high stability accelerometers and 3 inclinometers. The IMU is factory calibrated and compensated for temperature effects over its entire operating temperature range.
STIM318 is a cost-effective ITAR free solution for systems that only had FOGs as an alternative when reaching for the performance level of that STIM318 can offer.
ADVANTAGES
Full-Scale Range & Features
The STIM300 family of IMUs has a full-scale angular rate input range of ±400 °/s and the output is capped at ±480 °/s. Standard acceleration input range is ±10 g. Axis misalignment of as little as 1 mrad is achieved by electronic axis alignment. All of the IMUs in the STIM300 family product line require a single 5 V power supply and has a digital serial RS422 interface.
User-Selectable Output Formats
The STIM300 family of IMUs offers several user selectable output formats and sample rates for gyro and accelerometer data:
- Angular Rate
- Incremental Angle
- Average Angular Rate
- Integrated Angle
- Acceleration
- Integrated Velocity
- Incremental Velocity
- Average Acceleration
Unique Applications For the STIM318
The STIM318 IMU is well suited for stabilization, guidance and navigation applications in Industrial, Aerospace and Defence markets. The design is field proven in Military Land Navigators, Missile systems, Target acquisition systems, Airborne surveillance, DIRCM, Remote Weapon Systems, Launch vehicles and Satellites. In many applications, STIM318 can competitively replace IMUs based on Fiber Optic Gyros (FOGs) and improve system performance with respect to robustness, reliability, size, weight, power and cost.
