STIM377H IMU Non-GPS Aided Inertial Measurement Unit
Description
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.
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
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.
