The Terma Ground Segment Suite (TGSS) is a comprehensive set of tools that form a complete satellite control system, from satellite testing/checkout to operations. This allows the same tool set to be used throughout the whole spacecraft lifecycle. TGSS is built on more than 30 years of satellite operations and testing experience, and reflect many years of lessons learned. The tools are built with industry and de-facto standards, and are compatible with other systems. Through easy-to-use automation, intuitive user interfaces and customer-centric features, TGSS provides a modern performant platform to ensure customers are able to reduce the cost of their operations and testing activities without compromising on quality.

See all products that compose the TGSS suite. From test to operations, Terma covers the full spectrum of ground segment activities. Click on any of the products for more information. Find also a presentation of the Suite here.
