STIM277H MEMS GYROSCOPE
HERMETIC PACKAGE 3 AXES MEMS GYROSCOPE
View all MEMS Gyroscope options.
STIM277H is a small, tactical grade, affordable, robust and reliable, ultra high performance (Bias Stability 0.3°/h, ARW 0.15°/√h) 3 axis MEMS gyroscope built into 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.
An integrated 32-bit microcontroller enables flexible user configuration. Electronic axis alignment is standard.
ADVANTAGES
Shock & Vibration Resistant
The STIM 3-Axes MEMS Gyroscope Modules perform exceptionally well across many applications due to their very low vibration and shock sensitivity. They are designed to withstand 1500g of shock forces. Due to this extreme shock resistant capability, the gyroscopes are qualified according to high-performance aircraft vibration standards.
Long-Term Reliability & Robustness
STIM277H modules have been qualified to an equivalent of 20 years operating life. They also have an MTBF at 70k operating hours at 52 °C (according to MIL-HDBK 217), which is outperforming current FOG systems. Tuning of excitation and detection frequencies, as well as perfectly balanced vibrational masses, result in very low vibration and shock sensitivity in any direction.
High-Dynamics Applications
STIM277H is a good fit for satellite attitude & orbit control systems (AOCS) and launchers. Other applications are Industrial, Aerospace and Defense markets, for various platform stabilizations, pointing and navigation systems (e.g. antennas, cameras and gimbals), attitude heading reference systems (AHRSs), inertial navigation systems (INSs) for UAVs, AUVs, AGVs, UGVs and ROVs, smart munitions, 3D mapping systems, range finders, trains, robotics and more. For many applications STIM277H directly replaces FOGs and improves system solutions with respect to robustness, reliability, size, weight, power and cost.
