Plain-language guides for engineers specifying an inertial sensor, plus the documentation and drivers you need to evaluate and integrate one.
Everything you need to work with our IMUs: mechanical drawings and footprints, performance specifications, pinout and communication interface. Documentation is available for each variant, along with a shared section covering what applies across the whole family.
Software resources to bring our products into your platform: a C library for direct integration, along with drivers for ROS2 and ArduPilot, with PX4 support on the way. Each comes with usage examples and the reference material needed to get data flowing quickly.
Find setup guides, wiring details and technical specifications for the accessories that support our products.
An IMU measures how a vehicle is moving: its rotation and acceleration, using nothing outside the vehicle. What is inside one, what 6, 9 and 11-DoF mean, and what actually separates a good IMU from a poor one.
A photonic IMU, also called an optical IMU, measures rotation with light on a chip instead of vibrating silicon. The result is fiber-optic-class stability in a package closer to MEMS size and cost.
An AHRS computes which way a vehicle is pointing. It sits between a raw IMU and a full navigation system, and for a lot of platforms it is all you actually need.
An IMU measures motion. An INS computes where you are from those measurements. The right choice depends on one question: do you already have a navigation stack, or do you need position out of the box?
Three technologies dominate rotation sensing: vibrating-silicon MEMS, fiber-optic gyros, and the newer chip-based photonic gyros. OSCP builds and sells both MEMS and photonic IMUs, so this is the honest version of the comparison, including where each one loses.
