Latest inertial and accelerometer technology discussed at DGON ISS

14 September 2023

At the DGON ISS Symposium in Braunschweig, Germany on the 19th and 20th September 2023, Silicon Sensing will be in attendance to discuss recent developments in inertial sensors and systems including the performance of its latest tactical grade IMU and progress towards navigation-grade micro electro-mechanical systems (MEMS)-based inertial systems.  

Dr Mark Marshall, Chief Engineer at Silicon Sensing will also support a team from parent company Collins Aerospace who will present a paper on new accelerometer technology which is set to be brought to market through Silicon Sensing.

Dr Marshall explained: “The real benefit of MEMS technology lies in its size, weight and power consumption all of which is lower than alternative inertial technologies. In addition, the lack of moving parts means MEMS offers increased robustness and reliability.  However, the challenge has been to drive performance higher.”

Silicon Sensing’s latest IMU – the DMU41 – is already disrupting the market with performance that challenges the traditional performance envelope of the fibre optic gyro. This tactical-grade, 9 degrees of freedom unit is the highest performing silicon MEMS IMU on the market today. And trials of the company’s next generation technology are already demonstrating that step change in performance that will deliver navigation-grade MEMS products.”

As a joint venture, Silicon Sensing is also able to benefit from the expertise of its parent companies, Collins Aerospace and Sumitomo Precision Products. At DGON ISS the work of the Collins Aerospace engineering team in achieving significant gains in accelerometer technology will be presented. These developments will complement and strengthen Silicon Sensing’s inertial systems offering to the market.  

Marshall continues: “Our goal is to bring precise, sustained positioning and navigation to the most compact platforms; to those with the least available power; and to those that operate for prolonged periods and in the most severe environments. Current products have extended what has been possible, our next generation inertial systems and accelerometers will open doors tomorrow that we may not know exist today.”

Editor’s Notes:


The Inertial Sensors and Systems Symposium (ISS) – Gyro Technology, presents the latest state of inertial sensors and navigation systems as well as gyro technology. This includes applications of the technology, the development of new systems, components and test procedures as well as investigations on cost and marketing aspects.  As modern systems for navigation, localisation and guidance are increasingly making use of aiding data provided by additional non-inertial sensors, these topics will be focused on by the conference with growing interest.  Papers covering hybrid systems which fuse data from inertial sensors with that from GNSS, visual, infrared, radar or other sensors will also be presented.
