Motion Sensor – AIM
Adaptive Inertial Matrix for Offshore and Marine Application
Adaptive Intertial Matrix (AIM) is a unique hardware and software development based around MEMS technology (Micro Electrical Mechanical Systems) digital Inertial Measurement Units (IMU).
IMU units typically incorporate accelerometers, rate gyro sensors, and magnetometers. They have developed over a number of years and in so doing established a reliable and accurate measurement capability at an affordable cost.
The AIM system also has available additional analogue signal interfacing plus RS232/RS485. RJ45 Ethernet is also available for data export and presentation.
Distinct from other motion measurement systems, AIM takes advantage of MEMS technology price/performance capability by incorporating multiple IMU in order to establish an overall measurement performance consistent with a target application.
For example, the long period motion of a large rig or FPSO requires a very different sensor configuration from that experienced by smaller work vessels.
Key advantages can be summarized
- Multiple IMU establish greater accuracy than can be achieved with a single sensor.
- Multiple IMU establish continuous measurement through a wider dynamic range than is possible with a single sensor.
- Multiple IMU with spatial separation between sensors establish additional capability for motion identification and resolution.
