The Sensonor STIM300 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 individually for bias, sensitivity and compensated for temperature effects to provide highly accurate measurements.
On being powered up, the STIM300 performs an internal system check and synchronizes the sensor channels. The complete power-up sequence is acknowledged by providing special datagrams containing configuration data, serial number and part number.
Measurement data is transmitted as packages in a fixed format (datagram) at intervals determined by the sample rate together with a synchronization signal (TOV). Datagrams are binary coded to enable efficient transfer of data. Datagrams also contains an identifier, status bytes and a 32 bit CRC to provide fault detection in the transmissions. A status byte flags any errors detected by the system. The STIM300 can also be configured to only transmit data when triggered by a separate digital input signal (ExtTrig).
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.
