Introduction:

ER-MG2-50/100, a high performance MEMS gyro sensor with 0.01-0.02°/hr bias instability and 0.0025-0.005°/√hr Angular Random Walk, is specially designed for north seeking, pointing, initial alignment in logging tools/gyro tools, mining/drilling equipment, weapon/UAV launch systems, satellite antenna,target tracking system and so on. Thanks to the high performance, ER-MG2-50/100 can also used in high precision attitude measuring, stabilization control, positioning, navigating in navigation grade MEMS IMU/ INS, Land surveying/land mobile mapping system, railway train system, etc. So ER-MG2-50/100 is a best, cost effective, robust, reliable, small size, light weight, low power alternative of medium-low navigation grade FOG DTG with north seeking, precision attitude measuring , inertial positioning and navigation function.

The ER-MG2-50/100 High Performance North Seeking Gyroscope is a single-axis MEMS angular rate sensor (gyroscope) capable of measuring angular velocity up to a maximum of ±100°/s with digital output compliant to SPI slave mode 3 protocol. Angular rate data is presented as a 24-bit word.

The ER-MG2-50/100 is intended for north seeking applications. As an advanced, differential sensor design rejects the influence of linear acceleration, enabling the ER-MG2-50/100 to operate in exceedingly harsh environments where shock and vibration are present.

The ER-MG2-50/100 is available in a hermetically sealed ceramic LCC surface mount package, and is capable of operating at 5V supply and a wide temperature range (−45°C to +85°C).
