LPMS and FusionHub for Maritime Applications

With the combination of our high precision, rugged LP Motion Sensor (LPMS) lineup and our FusionHub data processing platform, we offer the perfect solution for a variety of applications encountered in the maritime field. For marine applications we specifically focus on our LPMS-IG1 and LPMS-IG1P units.

Vessel Impact Monitoring

LPMS devices contain highly sensitive 3D accelerometers. These accelerometers deliver acceleration data with up to 1000 Hz. This allows the long term monitoring of wave impact on a vessel or a specific part of a vessel. FusionHub simultaneously records position information of the vehicle either from the GPS receiver built into LPMS-IG1P or a generic NMEA input, and the output from the LPMS’s accelerometer.

For larger vessels several LPMS units can be daisy chained via CAN or RS485 bus. FusionHub allows for flexible recording and displaying of the acquired data and real-time processing results. This data can automatically be uploaded to the cloud or saved to local storage for post processing.

LPMS and FusionHub help you keep your personnel, passengers and the vessel itself safe and well maintained. The image below shows an example configuration inside a patrol boat.

An important aspect of the CAN and RS485 models of LPMS-IG1 is the possibility to network several units together with other peripherals. See below how several LPMS units could be combined with RFID sensors (for automatic personnel detection). FusionHub runs on Windows, Linux or Mac, therefore making the options for an output monitor very flexible.

COG-referenced Magnetic Heading

Magnetic heading on the water is hard: steel hulls, electrical loads and turns corrupt the compass, and a manual swing is impractical. Our Marine Heading filter, a part of FusionHub, fuses gyroscope, accelerometer and magnetometer with GPS course-over-ground - and the vessel’s true-heading feed when available - into a stabilized heading, calibrating hard-iron offset and deviation automatically and gating out magnetic disturbance.

A dedicated page shows the live heading, the health of each input, and the calibration state. Output streams over NMEA to autopilots and chart plotters, over MQTT for shore telemetry, and to the built-in map - a marine-grade heading and position source without a separate INS.

Note that optionally we offer this INS functionality integrated with the LPMS-IG1 firmware. This makes LPMS-IG1 or LPMS-IG1P a fully functional inertial navigation system in a compact and robust housing, at a very competitive price point. Ideal for your fleet of autonomous vessels.

Bonus Application: LPVR Mixed Reality Solution for Maritime Motion Simulators

Traditional maritime vessel motion simulators require large and expensive projection dome constructions to display immersive content to the user. Using LPVR, a dome can be replaced by a mixed reality headset. This allows for supreme immersion, strongly reduced setup effort and significant cost savings.

Same as the previous applications, this maritime simulation platform uses LPMS-IG1 for motion measurements and FusionHub for integrating headset tracking and visual pipeline with the simulator hardware.

Traditional mixed reality headsets don’t work on moving platforms or in a simulator installed on a vehicle such as a ship. LPVR uses specialised technology to decouple head motion and platform motion to allow reliable headset tracking.

Simulation specialist Cruden is using LPVR to decouple the rocking motion of the speed boat motion platform from the head motion of the user. In this way both the cockpit of the speed boat as well as the world around the boat can be shown to the pilot in training at the highest level of immersion.
