GENERAL DESCRIPTION

The KT-EX6-1 is a Micro-Electro-Mechanical System (MEMS) based Inertial Measurement Unit (IMU) designed to meet the needs of a range of applications across various markets including agriculture, AUVs, industrial equipment, robotics, survey/mapping, stabilized platforms, transportation, UAVs, and UGVs. With an industry standard communication interface, the KT-EX6-1 is easily integrated into the variety of architectures that these applications present. The extremelysmall size, light weight, and low power make the KT-EX6-1 ideal for most applications.
The KT-EX6-1 includes MEMS gyroscopes , accelerometers and inclinometers. In addition, the KT- EX6-1employs an internal environmental isolation system to attenuate unwanted inputs commonly encountered in real world applications. The internal isolation and other proprietary design features ensure the KT-EX6-1is rugged enough to meet the needs of the most demanding users.

1 The repeatability specifications represent analytical projections based on the following drift contributions and conditions: temperature hysteresis (−45°C to +85°C), electronics drift (high temperature operating life test: +110°C, 500 hours), drift from temperature cycling, rate random walk and broadband noise.
2 Bias repeatability describes a long-term behavior over a variety of conditions. Short-term repeatability relates to the in-run bias stability and noise density specifications.
