New accuracy class: LiMIS revolutionises MEMS technology
New standards in MEMS technology: LiMIS features an impressive balance between size, cost efficiency and performance.
FIBRE-OPTICS, MEMS AND SENSOR DATA FUSION –
THE BASIS FOR RELIABLE POSITION IMAGES
INNOVATIONS ARISE FROM TECHNOLOGICAL DEVELOPMENTS
The challenge of MEMS lies in making them smaller, less expensive and at the same time more accurate while maintaining the robustness and reliability. We are currently improving the accuracy of our MEMS rotation rate sensors step by step in an area in which this was not previously possible. As a result, we are achieving offset errors of less than 1°/h. These sensors will initially be available as single-axis sensors and will later be integrated into the LITEF-MEMS-IMU (µIMU). This currently has a volume of roughly 340 cm³. The next generation of our MEMS-IMUs will have a volume of approx. 240 cm³, while at the same time having reduced power consumption. And the generation after next of our MEMS gyroscopes will be an order of magnitude more accurate!

PUSHING BACK THE LIMITS OF WHAT IS TECHNOLOGICALLY POSSIBLE
With our core technology MEMS, we are developing ITAR-free solutions that set new standards. Increasingly small and accurate, but sacrificing nothing in robustness and reliability – this is the principle that LITEF pursues. For example, we are currently increasing the accuracy of our MEMS rate sensors. This enables applications for which the use of MEMS previously seemed impossible.
DEVELOPMENT SIGNIFIES IMPROVEMENT
Through the enhancement of FOG and MEMS technologies, LITEF is able to provide inertial reference systems for aviation that are characterised by light weight, low volume and low power losses, combined with great precision of sensor data. These attitude heading reference and navigation systems provide excellent reliability as well as the option, using an optimum combination of GNSS receiver data and inertial sensors, to provide 'hybrid' position and attitude information with a high bandwidth and low noise for navigation and flight control.

PUSHING THE LIMITS OF THE TECHNOLOGICALLY FEASIBLE
Acceleration sensors, rate sensors, inertial measurement units or positional reference systems – ITAR-free solutions from LITEF are also based on the further development of our core technology FOG. The ongoing miniaturisation of the systems means that the coming generations of sensors will be even more robust and even smaller. With our system knowledge, we go further and further in exploring the limits of the technologically possible, and certainly offer our customers new or better solutions to their problems.
OUR ENGINEERS KEEP AN EYE ON THE BIGGER PICTURE
Something that functions reliably and safely in practice is a complex process in theory. Talk to us if you are interested in the design and development of highly reliable, safety-relevant inertial sensors and systems.
PROMOTING OPERATIONAL EXCELLENCE
Operational excellence means examining all processes right across the company to identify areas for potention improvement. In particular, digitalisation is a top priority. This is LITEF's focus to secure solid and sustainable competitive advantages.

EXCELLENT KNOW-HOW AND PRODUCTION DEPTH
Our employees are experts, engineers, technical specialists, supervisors and skilled operatives. They are all experts; not only in aviation but also in the areas of defence and industrial applications. Considering where and how our products are deployed makes a good work ethic even more important; our employees work diligently and precisely, and are prepared to learn something new with every project. Hence, LITEF offers a broad range of further training options.
ROBOTICS AND ARTIFICIAL INTELLIGENCE PRESENT US WITH NEW CHALLENGES
Autonomous systems that act individually, in a network or in a swarm, present our customers and ourselves with new challenges. How can we manage that effectively? How can autonomous high-speed systems be controlled reliably? This includes everything becoming smaller, - the uncreasing demand for miniaturisation. We will reduce our inertial sensors and systems in size but shall retain their robust performance levels. In this way, LITEF will certainly be able to continue supporting its customers successfully.
