Inertial & Gyro Units -Memsic

MEMSIC offers a wide variety of Inertial sensors, Inertial Measurement Units (IMU), Attitude Heading Reference Systems (AHRS), Vertical gyroscopes (VG) and Fiber optic vertical gyros. These systems are unaided, high performance, solid-state attitude and heading reference systems intended for General Aviation and Unmanned Vehicles applications. The strap-down inertial system provides attitude and heading measurement with static and dynamic accuracy comparable to traditional spinning mass and directional gyros.


NAV Family

MEMSIC's NAV420 and NAV440 product families utilise MEMS-based inertial sensors and GPS technology to provide a high accuracy system for maneuvering platforms. These platforms include airborne systems (unmanned aerial vehicles, aircraft), land vehicles (tanks, HUMVEES), and marine vessels. The MEMSIC NAV420 and NAV440 are fully-integrated GPS-aided attitude & heading reference systems and GPS navigation solutions. The NAV440 provides full inertial data (angles, rates, accels) and GPS position, along with inertially derived velocity that provides significant improvement in stability and latency compared with stand-alone GPS velocity measurements.

AHRS Family

MEMSIC’s AHRS series of solid-state inertial measurement systems combines the functions of a Vertical Gyro and a Directional Gyro to provide measurement of Roll, Pitch, and Heading angles. The AHRS440 is an Attitude & Heading Reference System (AHRS) that utilizes MEMS-based inertial sensors to provide an unmatched value in terms of both price and performance. The AHRS500 is the most widely used MEMS-based Attitude and Heading Reference System for avionics upgrades. The AHRS510GA is a field proven high-reliability MEMS Attitude & Heading Reference System that supports all of the standard ARINC 429 message labels for an AHRS. The AHC525 is an Attitude & Heading Card designed specifically for OEM avionics system applications where an embedded AHRS solution is required.
