Xsens Unveils Advanced Heave Technology for Marine Applications
Xsens is excited to announce a significant upgrade for its Xsens Sirius and Xsens Avior inertial measurement units (IMUs), which now feature advanced Heave capability. This update allows for centimeter-level vertical displacement measurement, thereby delivering superior real-time stabilization and wave compensation for various marine applications.
Revolutionizing Marine Motion Data
With the latest firmware upgrade, marine engineers can now access comprehensive motion data, including roll, pitch, yaw, and Heave, from a single compact sensor. This upgrade eliminates the need for bulky systems or external processing, ensuring high precision for offshore platforms, vessels, docking systems, marine robots, buoys, and surveying tools.
Real-time Response for Active Applications
The newly implemented Heave output operates at a staggering rate of up to 100Hz. This enables the rapid response required for effective active stabilization and wave compensation systems. Notably, all processing is handled on-device, simplifying integration and significantly reducing latency.
Unmatched Accuracy in Wave Conditions
Xsens Motion Reference Units (MRUs) equipped with the Heave capability deliver real-time accuracy within 5 cm for wave periods extending up to 29 seconds. This precision is crucial for a myriad of marine applications. Moreover, for longer wave periods reaching up to 40 seconds, the accuracy remains commendably at around 6 cm, significantly outperforming that of comparable industrial-grade MRUs.
Insights from the Experts
Ayush Sharma, Algorithms Engineer at Movella, emphasized the advantages of this enhanced functionality, stating, "Engineers now get vertical displacement data directly onboard, alongside roll, pitch, and yaw. This provides marine customers with the motion reference needed for stabilization and compensation systems without the overhead of tactical MRUs."
Seamless Integration through Firmware Update
The Heave algorithm is available immediately as a firmware update for existing Xsens Sirius and Xsens Avior units. Users will find that the update requires no hardware changes, making it accessible for current users with no additional costs. New units will come pre-installed with this feature, ready to deploy right out of the box. Heave output can be activated through a simple setting adjustment in the MT Manager software or the Xsens Software Development Kit (SDK).
Designed for Ease of Use and Flexibility
Xsens Avior functions as a compact OEM module, perfect for various embedded system designs, while Xsens Sirius serves as a standalone MRU that is contained in a rugged IP68 housing, making it suitable for harsh environmental conditions and compliant with MIL-STD-202 standards.
Both sensor models support a connection to RS-422, CAN, and UART interfaces and come with development kits for effective prototyping. They feature free SDKs compatible with programming languages including C/C++, Python, ROS1, ROS2, and MATLAB. Furthermore, all units satisfy CE, FCC, and RoHS regulatory requirements and are ITAR-free.
Global Availability and Customer Support
The Xsens Avior and Xsens Sirius MRUs are accessible worldwide through Movella and its authorized partners. Interested customers can find detailed specifications, datasheets, and ordering information on the Movella site or contact a Movella sales representative for assistance.
