Our story

At S[&T] we contribute to a safer life on earth by translating space data into valuable and actionable insights. We oversee data from instruments to application, and apply our expertise within our software frameworks, information products and consultancy.

Our society relies on space and scientific instruments for climate change monitoring, navigation, defence and national security, and other crucial services we all use in our daily lives. These instruments produce an enormous quantity of complex data, and our goal is to unlock its value.

We have more than 20 years of experience working on instrument calibration, the creation of data quality monitoring tools, the development of real-time data processing frameworks, and the development of application-specific algorithms. With this, we help organisations, governments and industries to strengthen their information position and thereby improve their decision making. We focus on the following domains: Space & Science, Defence & Security, Environment & Sustainability, and High-Tech Consulting.

Sensing problems. Developing solutions.
Our Sensing and Control Systems provide new insights and access to what is happening in harsh environments. Scientific Data Processing ensures that you get the most out of the world's most under-utilized precious resource: data. We can then turn that data into smart decisions with our Intelligent Software Applications. Or if you need on-site support, we have…
