About the company & team
Satellite operations are becoming increasingly complex. With more satellites, more diverse missions, and growing demands for automation and operational efficiency, mission operators require ground segment solutions that are flexible, scalable, and easy to adapt. Traditional ground segment solutions are often highly customised for individual missions, limiting scalability and increasing operational complexity.
At S&T we are developing software solutions for clients who operate their own satellite constellations. We are developing a satellite Mission Control System, which can operate multiple satellites from different providers in one single system. With this development we are changing the approach of traditional ground segment solutions by developing a modular, software-first ground segment platform that combines reusable building blocks for mission planning, tasking, satellite operations, monitoring, and data workflows. Our ambition is to create a scalable operational environment that enables efficient management of current and future satellite missions, reduces complexity, and accelerates mission deployment across civil, commercial, and defence applications.
The team is part of the Intelligence, Surveillance & Reconnaissance (ISR) program, a team of 12 (and growing) enthusiastic and social developers, data scientists and FPGA-engineers. The team develops solutions for Earth Observation data processing, both on-ground or on-board satellites. ISR is part of the Defence & Security unit, where we are working on innovative solutions that leverage space technologies for Defence and Security.
