NGIMU


High-performance IMU with USB, Wi-Fi, serial, SD card logging

Next Generation IMU

The Next Generation IMU (NGIMU) is a compact IMU and data acquisition platform that combines on-board sensors and data processing algorithms with a broad range of communication interfaces to create a versatile platform well suited to both real-time and data-logging applications.

On-board sensors include a triple-axis gyroscope, accelerometer, and magnetometer, as well a barometric pressure sensor and humidity sensor.  An on-board AHRS sensor fusion algorithm combines inertial and magnetic measurements to provide a drift-free measurement of orientation relative to the Earth.  Each device is individually calibrated using robotic equipment to achieve the specified accuracy.  Additional, external sensors, such as force or bend sensors, can be connected to the 8-channel analogue input interface.  Serial data sources, such as GPS modules, can be connected to the auxiliary serial interface.

Real-time communication is achieved via USB, Wi-Fi, or serial/RS-232. Data may also be logged to an on-board micro SD card. The NGIMU uses the popular OSC communication protocol and so is immediately compatible with many software applications and straight forward to integrate with custom applications with libraries available for most programming languages. The use of this protocol and the range of communication interfaces make the NGIMU compatible with just about any platform, from an Arduino to an i-phone.
