• STIM202 Gyro Module

mems gyro STIM202 description :

STIM is a cluster of 1, 2 or 3 high accurate MEMS-based gyros housed in a miniature package. Each axis is factory calibrated for bias and sensitivity, and compensated for temperature effects to provide high-accuracy measurements. For many applications the excellent performance of STIM202 will replace FOG’s and improve system solution with respect to robustness, reliability, size/ weight, power and cost. This is accomplished by combining the well proven Sensonor ButterflyGyroTM with full digital operation. Input range and output formats The STIM202 full-scale angluar rate input range is 400°/s. Selectable output formats are angular rate or increment angle. Reliability and robustness Perfect tuning of excitation and detection frequencies, as well as perfectly balanced vibrational masses, result in very low sensitivity to vibration and shock. For use in extreme environments, the STIM202 provides a vibration isolated internal assembly to avoid rectification errors. Interface The unit is powered by a single +5V supply and communicates via a Plug & Play high-level RS422 interface. Flexibility and self diagnostics The use of a 32-bit RISC ARM microcontroller provides flexibility in configuration, e.g. for choices of output unit, sampling frequency, LP filter cut-off frequency, RS422 bit rate and line termination ON/OFF. The gyro module provides a diagnostic function, that will flag any type of errors in the system. For more advanced users, the STIM202 may be set in Service Mode, where all configuration parameters may be intermediately or permanently changed by overwriting current settings in the flash memory.
Service Mode also provides ability to perform single measurements and to access more diagnostic information. Evaluation kits Evaluation kits are available, supporting initial testing and device configuration. The starter kits are small, flexible and communicate via USB.
Additional PCI cards are offered for more extensive testing or characterization. The RS422 connection of the PCI card is directly compatible with the STIM202 communication cable included in the starter kit. Applications The STIM202 is designed to replace FOGs in general, and enables new areas of use.
Typical applications for the product is attitude heading reference systems (AHRSs), flight recorders, platform stabilization (e.g. antennas, cameras, gimbals, etc.), remote weapon systems (RWSs), turrents, mid range missiles and rockets, high performance industrial applications, unmanned aerial vehicles (UAVs), autonomous underwater vehicles (AUVs), space applications, etc.

Avionic & Defense

Avionics GYRO MEMS

Two key emerging defense-related applications for gyros are munitions and unmanned (land and aerial) vehicles. When performance permits, precision MEMS gyro solutions will be the enabling and preferred choice due to superior capability in respect to robustness, reliability, size/weight, power and cost; compared to solutions based on RLG or FOG technologies.

Inertial navigation systems, often coupled with GPS, provide accurate, jam-resistant guidance for artillery shells, bombs, missiles and torpedoes.

Gyros and IMUs based on MEMS technology are small, light and affordable solutions for seeker, antenna and gun/turret stabilization.

MEMS Gyros


Inertial navigation systems are often mandatory for Remote Operated Vehicles (ROVs) and underwater robots. Compared to hydro acoustic position reference systems they offer longer operation distance, possess better autonomous ability (auto heading) and offer higher potential accuracy.

Unmanned Aerial Vehicles (UAVs) relay on the use of inertial navigation and guidance systems often in combination with GPS reference. Applications include surveying for hot spots in fire-prone areas and national and international (land and sea) border and fence patrol.

MEMS Gyros


The ability to position a marine structure or vessel can be compromised by everything from waves, wind and water depth/heave to working at night or in foggy conditions. A dynamic position control system with integrated gyro sensors will improve the accuracy and capability of such systems.

For similar reasons, satellite antennas, cameras and survey instruments used under maritime conditions, need platform and gimbals controls.

For underwater operations and ROV maneuvering, inertial navigation and guidance systems play an important role complimentary to acoustical methods. For autonomous submarines inertial based systems is mandatory.

Platform, machine and robotic controlGYRO MISSILE

Gyro sensors are used in all sorts of control systems to meet demanding dynamic operation for seeker stabilization and camera and antenna pointing. An example is a ship rolling and pitching in the sea. Antennas in such applications require gyro stabilization in order to accurately receive or transmit data. Another example is gimbals operation of camera mounts on ships, helicopters or terrain moving vehicles. Balance control is needed for semiautonomous operation of mobile robots and wheelchairs. For robot tools and utility machinery inertial sensors play an important role in the adaptive position control system.

During patrol, rescue and firefighting operations the safety and efficiency of the teams rely on accurate information regarding position and movements. The use of inertial tracking and guidance is one of the most robust, independent and ad hoc solutions that exist. Specific information on each member's (person or vehicle) location and specific movements can be sent from the inertial system by RF means to a base station laptop or information system. During such conditions GPS can only be used for reference purposes due to GPS coverage uncertainty, extreme dust or weather conditions, indoors operation, under water operations or down hole operations.
