STIM377H IMU

non-GPS AIDED INERTIAL MEASUREMENT UNIT

STIM377H is a small, tactical grade, low weight, high performance non-GPS aided Inertial Measurement Unit (IMU) in a hermetic package. The package is a hermetic aluminum enclosure with a glass-to-metal sealed electrical micro-d connector and a laser-welded lid to secure long-term hermetic operation. All parts are tested for fine and gross leak to conform to MIL-STD-883J, Class H.

STIM377H 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.

STIM377H is a cost-effective ITAR free solution for systems that only had FOGs as an alternative when reaching for the performance level of that STIM377H can offer.

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
Orbit Control Applications

STIM377H and the STIM380H are a good fit for satellite attitude & orbit control systems (AOCS)
and launchers. Other applications are 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, the STIM377H and the STIM380H can competitively replace IMUs based on
Fiber Optic Gyros (FOGs) and improve system performance with respect to
robustness, reliability, size, weight, power and cost.
