When Success is the only Option

For more than 45 years, we have built mission critical equipment for every conceivable type of satellite.

Satellite Equipment Built and Tested to Last

Through vigorous and diligent testing, we ensure that all satellite systems leaving our production facilities will withstand the harsh environment for which they are destined.

For more than three decades, we have been a trusted supplier of mission critical equipment for commercial, national and international space missions. We supply equipment and software for, e.g., Earth observation missions, Geo-stationary telecommunication missions and the International Space Station. Through the years, we have been actively collaborating with our clients, which have given us our far-reaching ability to exceed the industry standards of today.


We have delivered flight equipment for all ESA interplanetary and planetary missions, e.g., Rosetta, Solar Orbiter and Bepi Colombo.

High efficiency, low weight. Our power units have earned their credibility in crucial missions such as empowering a Mars rover for ESA.

Documented flight heritage. Find the perfect balance between new and proven technology, with high Technology Readiness Levels.

Cutting edge, yet mission proven, solutions

At Terma, we take pride in the missions we have accomplished. We know that the equipment we provide is critical to the entire mission of the satellite – no matter whether it is about to uncover the secrets of Mars or ensure a stronger TV-signal in Oklahoma.

Our aim is to provide the perfect balance between cutting edge and mission proven technology. We provide unique, customized equipment for each task – but always built on the most proven technology.

In the world of space ventures, we have already established ourselves as a trusted partner and supplier. As examples, our equipment is currently powering the BepiColombo satellite towards Mercury, we will provide a power unit for the next Mars Rover (the Sample Fetch Rover for ESA) and we have led the team that developed an instrument now installed on the International Space Station, registering lightning bolts in the outer atmosphere.

Independent Contractor for Space Segment

We are a privately owned company and fully independent from other players in the space business. This gives us the autonomy to be fully focused on our customer needs – this means you are assured to get the best possible equipment and service solution on the market.

Best-in-class Quality Assurance

We perform all testing in-house and thus dramatically decreases your risk of technical issues during the many years of service you expect from your satellite.

At Terma, we are aware that if any component fails, you jeopardize the entire project. For this reason, we have instilled an array of diligent quality assurance processes, and ensure we have state-of-the-art testing facilities in place in-house at any time.

Timely delivery of Space Equipment

If implementation is delayed on one end, often times a bottleneck occurs, creating several other delays. At Terma, we are acutely aware of the responsibility that we carry for your space project to result in success.

Supplying hardware and software successfully for projects such as Venus Express and Mars Express, we have earned our status as a trusted partner in both producing and integrating space equipment.

Solutions and products for Space Segment

We design and manufacture a wide variety of trusted equipment, each with impressive flight heritage. Our flight software helps you control your spacecraft in a reliable manner and our checkout systems ensure you can test your spacecraft thoroughly and efficiently before launch.

Flight Processor Emulators

Exercise your flight software in a simulated environment

Our processor emulator, TEMU, is used to run unmodified flight software in a simulated environment – including faster than real time. This is important for flight software validation facilities and operational simulators. TEMU has instruction-level emulation accuracy and supports a number of processors. The flight software for PLATO is developed using the Terma TEMU Emulator.
