Terma Ground Segment Suite

Terma is a leading supplier of ground system solutions to support satellite missions. Terma has worked with all system components and associated processes for managing, monitoring, and controlling satellites.


The Terma Ground Segment Suite (TGSS) is a comprehensive set of tools that form a complete satellite control system, from satellite testing 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 it reflects 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 operations and testing activities without compromising on quality.

Satellite Control Systems

At the heart of a ground segment is a satellite control system – this is provided by our CCS5 product. In order to prepare for the operations, our PREP product is used, while STAT processes the data (TM, TC. etc) that is the result of the operations. Interfaces to ground stations are part of CCS5 – for SLE based interfaces, the UNIS product is needed.

Test and Simulation

The core on ESGE is the central checkout systems - this is available in single user (TCS) or multi-user (CCS5) versions. PREP and STAT are used to prepare for testing activities and analyse the results of those tests. TEMU is a processor emulator for a number of flight processors and is at the heart of a Software Validation Facility or an Operational Simulator

The video is a demonstration of CCS5 configured to support a constellation/fleet of 30 satellites, with the visualization provided by the TRACK product.

The simulation of each satellite is quite simple – it is possible to force error conditions, and then run contingency procedures to correct the problem. The satellites are also simulated with inter-satellite links.

This shows both:

  • how the user interacts with the constellation and the satellites in that constellation,
  • how, when an error occurs, it is visualized in a manner easily recognizable to the users so they can immediately start with investigation and corrective actions.





This scenario can also be demonstrated to potential customers.
