Silicon Sensing’s Technology Supports Autonomous Mayflower Voyage - 20/01/2020

Two Silicon Sensing Systems ultra-precise AMU30 inertial measurement units (IMUs) will provide critical navigation data to the autopilot capability for the Mayflower Autonomous Ship (MAS) throughout her milestone transatlantic voyage this autumn. Setting sail this September, the 15-meter long, 5-ton MAS400 will repeat the Mayflower’s original epic voyage made 400 years ago.

Led by marine research organization ProMare and powered by IBM, she will sail from Plymouth, England to Plymouth Massachusetts, USA. Instead of a captain and crew, she will use computer vision, machine learning, cutting-edge technologies and sensors to navigate and detect hazards.  

Silicon Sensing’s AMU30 devices will form two vital units within the MAS navigation suite, constantly delivering precise 3-axis data on angular rate and acceleration plus roll, pitch and heading angles, altitude and pressure, and temperature to the ship’s autopilot.

Scientific Laboratory

Travelling at a maximum speed of 12 knots, MAS is expected to take just 12 days to reach the coast of Massachusetts – a fraction of the 66 days of the voyage four centuries ago. Throughout the voyage, the ship will also function as a scientific laboratory. On-board sensors will transmit data for critical research programmes in areas such as maritime cybersecurity, marine mammal monitoring, ocean microplastic analysis and sea-level mapping.   

AMU30 is Silicon Sensing’s first product to combine high-performance micro-electro-mechanical systems (MEMS) IMU with a full attitude and heading reference system (AHRS). The device comprises a proven ten-degree-of-freedom IMU with a three-axis magnetometer, pressure sensor and a sophisticated AHRS algorithm. This new device has been developed to replace far heavier, larger and more costly fibre-optic gyro-based devices, delivering impressive all-MEMS inertial performance, including exceptional bias stability and low noise characteristics, with a proven, embedded Kalman filter-based AHRS algorithm.

About the Mayflower Autonomous Ship Project

Driving the MAS project are ProMare (a charitable research foundation), IBM and Plymouth University. Also coming on board is the UK's University of Birmingham, which will be responsible for the use of virtual, augmented and mixed reality technologies in the MAS mission. Birmingham's Human Interface Technologies Team is leading the development of a Mixed Reality Telepresence Science Station, which will allow schoolchildren and members of the public around the world to experience the transatlantic mission (

About the Celebration and History of Mayflower

The original Mayflower voyage carried 102 passengers and a crew of 30 to a new life in the pursuit of religious freedom and opportunity. They set sail from Plymouth, England for America in September 1620 and became known as the Pilgrims. They spent 66 days at sea with no guarantee of reaching America yet defied the odds and successfully established a permanent settlement at Plymouth Massachusetts.

About the University of Birmingham's Human Interface Technologies Team

The Human Interface Technologies (HIT) Team, based in the Extreme Robotics Laboratory at the University of Birmingham, has been pioneering the development and uptake of virtual, augmented and mixed reality and telerobotic technologies in the UK since 2003, building on over 32 years of experience in those domains. The team's award-winning research is helping to avoid the 'technology push' failures evident in the 1980s, 1990s and early 2000s by developing and evaluating demonstrators in defence, healthcare, heritage and advanced robotics that emphasize the importance of exploiting human factors knowledge during the design of innovative human-system interfaces (

About the University of Plymouth

The University of Plymouth is ranked as one of the UK's top ten modern universities in the UK (Times Higher Education Young University Rankings 2019), and its origins go back over 150 years to the School of Navigation, which was formed in 1862. The University covers a broad range of disciplines through its research and teaching and is a global leader in marine and maritime research, including marine litter research, and was the first university to identify the widespread occurrence of microplastics  (
