Overview

The Sensonor STIM318 MEMS IMU is small, lightweight, tactical grade IMU that contains 3 high accuracy MEMS-based gyros, 3 high stability accelerometers and 3 high stability inclinometers. Each axis is factory calibrated for bias, sensitivity and compensated for temperature effects to provide high-accuracy measurements.

Measurement data is transmitted as data packages complete with a 32 bit CRC (Cyclic Redundancy Check) to provide a high level of error checking, flagging any errors detected by the system. The unit can also be configured to only transmit data when triggered by a separate digital input signal.

The IMU can be put in Service Mode that allows users to change configuration parameters. Commands and responses in Service Mode are in ASCII format to provide for using terminal-type software during product integration. Service Mode also enables single measurements and diagnostics to be performed and a higher level of error detection obtained.

The STIM318 also features Bias Trim Offset Mode in which users are able to trim the bias of each of the nine axes individually.
