Sensonor, a leading developer of miniature tactical-grade gyroscopes and IMUs (inertial measurement units), has partnered with Unmanned Systems Technology (“UST”) to demonstrate their expertise in this field. The ‘Silver’ profile highlights how their high-performance MEMS inertial sensors can be used to provide navigation, positioning and control for UAVs (unmanned aerial vehicles), UGVs (unmanned ground vehicles), UUVs (unmanned underwater vehicles) and other robotic platforms.
The STIM202 is a 3-axis tactical-grade MEMS gyro module with internal shock absorbers that work as a low pass filter, allowing the unit to operate unaffected in environments with shocks containing high energy across a large frequency spectra. The module can replace FOGs (fiber optic gyros) in many applications, providing a lower SWaP (size, weight and power) footprint and a highly reliable and robust solution.
The module features an integrated 32-bit RISC ARM microcontroller, allowing users to configure a wide range of parameters such as output formats, sampling rate, LP filter cut-off frequency, RS422 transmission bit rate and more. Each of the module’s three axes has been electronically aligned and factory-calibrated for bias and sensitivity, and temperature compensated over the full operating range.
The STIM210 is a tactical-grade MEMS gyro module that can be provided with one, two or three axes of measurement. The unit features high resistance to shock and improved bias error over temperature gradients and improved non-linearity.
The module’s integrated 32-bit RISC ARM microcontroller provides selectable output formats including angular rate, increment angle, average angular rate and integrated angle, as well as a configurable sample rate of up to 2000 samples per second.
The STIM277H is a tactical-grade 3-axis MEMS gyro module that has been hermetically sealed and designed to meet the exceptional long-term reliability and stability needs of space and defense applications. Housed in an aluminium enclosure with SurTec650 surface treatment and a glass-to-metal sealed electrical Micro-D connector, the unit has been HTOL (high-temperature operating life) tested for a 20+ year lifespan.
Based on and backwards-compatible with the STIM210, the STIM277H has been factory-calibrated across all axes for bias and sensitivity, and compensated for temperature effects. All components have been tested for fine and gross leak according to MIL-STD-883J.
The STIM300 is a miniature tactical-grade IMU incorporating three high-accuracy gyros, three high-stability accelerometers and three inclinometers. Highly resistant to shock and vibration, the module is a cost-effective ITAR-free alternative to FOG IMUs.
Incorporating a RISC ARM microcontroller, the device can be easily configured, providing a range of options as well as user-selectable output formats for data such as angular rate, incremental angle, integrated angle, acceleration and incremental velocity. The STIM300 IMU has been factory-calibrated and compensated for temperature effects over the full operational range.
The STIM318 is a lightweight, compact tactical-grade IMU designed to provide enhanced performance for challenging guidance and navigation applications. The unit incorporates three high-accuracy gyros, three high-stability accelerometers and three inclinometers.
The device features a Bias Trim Offset function that allows users to individually zero out any bias offset on any of the nine axes. The bias offsets can be stored in flash memory, allowing configurations to remain in effect even after powering off the IMU.
The STIM377H is a high-accuracy tactical-grade IMU designed to withstand the extreme environments of challenging space and defense applications, providing enhanced long-term reliability and stability. The unit is enclosed in an aluminium package with SurTec650 surface treatment and a glass-to-metal sealed electrical Micro-D connector, and has been fully factory-calibrated and temperature-compensated.
Incorporating a 32-bit RISC ARM microcontroller, the module features a Service Mode that allows full configuration of all device parameters, as well as single measurements and advanced diagnostics. The STIM377H is an excellent ITAR-free alternative solution to more costly FOG-based IMUs.
