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.


Introduction

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 SCS5 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 SCS5 – 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
