New Standard for Industrial-grade MEMS Motion Trackers

Xsens, headquartered in The Netherlands, has launched its new MTi product portfolio for industrial applications such as antenna/camera stabilisation and unmanned system control. With the introduction of this fourth-generation high-performance product line, MEMS-based motion trackers (IMU, VRU, AHRS and GPS/INS) now match the accuracy and robustness requirements of many applications that until now have depended on fibre-optic gyroscope-based (FOG-based) solutions. The new MTi builds on the benefits in size, price, power consumption and flexible interfacing options Xsens’s customers have relied on for the past 12 years. With 7 distinctive models in the product portfolio offering 3D orientation, 3D position, 3D... (read more)

Qualifying Heave Performance at Sea

Comparison of ORE MEMS-based MRU Heave Measurement with RTK-GPS
When accelerometer-based heave units were developed, there were limited options for verifying their performance at sea with a recognised standard. With real-time kinematic (RTK) global positioning system (GPS) devices, surveyors today can achieve accuracies of 2cm in altitude measurement. With the advent of small, low-cost, low-power, micro-electrical mechanical systems being employed for motion-sensing, a compact and cheaper alternative is available to measure heave. We have verified the heave of our motion reference units at sea with RTK-GPS.

Applanix Product Integration

Applanix has incorporated MEMS (Micro-Electro-Mechanical Systems) technology into its line of Position and Orientation System products. The state-of-the-art, low-noise, micro-machined quartz components are compact, durable and designed for use in a high-vibration environment. The custom-designed sensors are at the forefront of MEMS technology, manufactured by BEI Systron Donner Inertial Division (SDID) of Concord, California, US, a division of BEI Technologies, Inc. SDID solid-state sensors are micro-machined using photolithographic processes, producing components comparable to small ring laser and fibre-optic gyros. Applanix chose the SDID system over competing technologies because of the high-precision requirements of their POS products and SDID expertise in... (read more)

From the national Societies: Hydrographic Society Benelux

Integrated Navigation WorkshopOn Friday 15th December 2006 the Netherlands Institute of Navigation (NIN), Geo-Info Nederland (GIN) and the Hydrographic Society Benelux branch (HSB) held a workshop on integrated navigation, with emphasis on MEMS (micro-electromechanical systems) technology, hosted by the National Aerospace Laboratory (NLR) in Amsterdam. About 75 people attended the workshop.In the first presentation Prof. Durk van Willigen of Reelektronika gave an overview of integrated navigation, discussing methods of integration and aspects such as accuracy, integrity, availability and reliability. He illustrated his talk with his own experiences in the field of car navigation, typically based on low-cost sensors.Next, Sam Storm... (read more)

Impact Subsea Launches ISM3D AHRS

Impact Subsea has announced the launch of a groundbreaking underwater Attitude & Heading Reference System - the ISM3D. It utilises high-grade MEMS-based accelerometers, angular rate gyroscopes and magnetometers that feed into a fusion engine driven by a dual-core micro-processor. The unit provides heading to ±0.5° of local magnetic north with pitch and roll to ±0.05° accuracy. For optimal performance, a hard and soft iron calibration can be performed on the unit once installed on the ROV, AUV or other underwater platform. This ensures that a consistently accurate heading is provided at all times. In areas where a large amount of steel... (read more)

Silicon Sensing Supports 'Mayflower' Autonomous Ship Project

To mark the 400th anniversary of the 'Mayflower' setting sail to America with 102 intrepid early settlers on board, a team has a plan to design and build a fully autonomous ship to make the same Atlantic crossing, completely unmanned, in 2020. The team is led by US-owned but UK-based (Plymouth) firm MSubs and includes Plymouth University and ProMare (a charitable research foundation). Silicon Sensing is to provide a package of support to help turn the MAS400 concept into reality. During the voyage, the Mayflower Autonomous Ship – MAS400 – will conduct a series of scientific experiments before arriving at... (read more)
