MEMS IMU (Inertial Measurement Units)
A MEMS inertial measurement unit (IMU) combines micromachined gyroscopes and accelerometers — typically three of each — in a single calibrated module that outputs angular rate and linear acceleration. MEMS IMUs trade the ultimate precision of optical sensors for compact size, low power, and solid-state ruggedness.
Catalog MEMS IMUs span tactical to industrial performance tiers, with published gyroscope bias stability, angular random walk, dynamic range, and bandwidth, plus matching accelerometer specifications. Several models add inclinometer or barometric channels. Digital interfaces (SPI, UART/RS-422) and factory calibration are documented per model. Selection is driven by required bias stability, environmental conditions, interface, and size/power constraints.
Catalog MEMS inertial measurement units. Full gyroscope, accelerometer, interface, and environmental specifications are published per model — compare models on their individual specification pages, where every parameter carries its stated measurement conditions.
Key Selection Parameters
Gyroscope Bias Stability
The dominant error term for unaided attitude and heading. Match the 1σ in-run value to the mission duration and aiding scheme.
Angular Random Walk
Noise integrated into attitude over time. Matters most for short-term, high-bandwidth stabilization.
Dynamic Range
Gyroscope and accelerometer full-scale range must cover the platform's worst-case rotation and acceleration with margin.
Interface & Data Rate
SPI vs UART, output rate, and latency must fit the host navigation computer's timing budget.
Environmental Envelope
Operating temperature, shock, and vibration ratings against the platform profile — including any full-temperature bias modeling.

Selection Workflow
- 01
Set the bias budget
Derive the allowable gyroscope bias stability from mission duration, aiding availability, and attitude accuracy targets.
- 02
Cover the dynamics
Confirm gyroscope and accelerometer ranges exceed worst-case platform motion with margin.
- 03
Check the environment
Match temperature range, shock, and vibration ratings to the installation; review full-temperature bias behavior.
- 04
Inquire with the shortlist
Send the candidate models and operating conditions — configuration, interface options, and availability are confirmed per project.
Typical Applications
- Attitude and heading reference in unmanned platforms
- Stabilization of antennas, gimbals, and electro-optical payloads
- GNSS-aided inertial navigation
- Platform motion sensing and control
Testing Considerations
- lab_profileCompare bias stability and random walk only under stated measurement conditions (averaging time, temperature, Allan deviation method).
- lab_profileVerify full-temperature bias behavior against the real thermal profile, not only room-temperature figures.
- lab_profileRun a representative vibration profile if the unit will operate near its bandwidth limits.
