STIM300 IMU
Non-GPS Aided Inertial Measurement Unit
View all Inertial Measurement Units.
STIM300 is a small, tactical grade, low weight, high performance non-GPS aided Inertial Measurement Unit. It contains 3 highly accurate MEMS gyros, 3 high stability accelerometers and 3 inclinometers. The IMU is factory calibrated and compensated over its entire operating temperature range.
STIM300 is a cost-effective ITAR free solution for systems that only had FOGs as an alternative when reaching for the performance level of that STIM300 can offer.
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 via a RS422 interface. The use of a 32-bit RISC ARM microcontroller provides flexibility in the configuration, like choice of output unit, sampling frequency, LP filter -3dB frequency and RS422 bit-rate and protocol parameters. For more advanced users, STIM277H may be put in Service Mode. In this mode all the configuration parameters can be temporarily 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.
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
Versatile Applications
The STIM300 IMU is well suited for stabilization, guidance and navigation applications in Industrial, Aerospace and Defense 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, STIM300 can competitively replace IMUs based on Fiber Optic Gyros (FOGs) and improve system performance with respect to robustness, reliability, size, weight, power and cost.
