TDK Corporation launches a new high performance and fault-tolerant InvenSense inertial measurement unit (IMU) family targeted at industrial applications. The new products, IIM-46234 and IIM-46230, include multiple 6-axis sensors, each of which can measure three dimensions of linear acceleration and three dimensions of rotational rate.
With its ability to take precise measurements in harsh environments characterized by the presence of vibration and wide temperature variations, the IIM-4623X product family is applicable to a variety of navigation and stabilization applications including precision agriculture, construction machinery, aerial vehicles, and industrial robots. An example application would be a construction vehicle that can combine IIM-4623X measurements with data from a global navigation system, such as GPS, to determine precise position, attitude, and motion in real-time. Such real-time information is crucial for increased automation, efficiency and safety of mobile industrial machinery. The new family also integrates TDK’s unique SensorFT feature for fault tolerance.
IIM-46234 and IIM-46230 products deliver:
- Precise measurements enabled by highly accurate and ultra-low noise sensors
- Factory calibration ensuring that the measurements are reliable over a wide temperature range
- A microsecond accurate timestamp with all the sensor measurements enabling accurate time transfer with rest of the system
TDK customers can combine the high-performance industrial IMU family with the InvenSense Coursa Drive software to deliver a market-ready inertial navigation system (INS) with minimal development cost and resources. In real-time, Coursa Drive provides high-rate, 100 Hz delta positions and orientation to the AV system, complementing the lower-rate position references from GNSS and perception systems. For improved system fault-tolerance, Coursa Drive can provide decimeter position precision for short periods when the GNSS or perception systems are uncertain or unavailable.
