Read how we have helped our customers in designing and developing complex industrial applications

Mipro

SSF acts as a key partner to Mipro. One of the areas SSF works in is validation testing for Mipro in a project of highest safety criticality level (SIL4). By integrating a team from SSF into Mipro’s verification and validation organization, SSF has helped customer to achieve goals in the highly demanding timeframe. The work consist of validation of the railway interlocking software product, which is responsible of the safety and reliability of the railway traffic. With the experience from safety critical projects, SSF has also been able to support Mipro with the verification tasks.

“The collaboration with SSF has always been easy, and the team that SSF provides is experienced and professional.”, says Jari Pylvänäinen, Director, Safety related systems. “As a fast growing expert company, Mipro needs partners that always excel in the tasks and support us in our own success.“

EKE-Electronics

SSF has had the opportunity to support EKE-Electronics in the development of safety critical railway systems in several implementation projects. The cooperation was initiated with specification of an in-house process for developing software intensive products according to railway safety standards and regulations. The goal was to tailor the generic process of the standards to a set of practical techniques and measures that fit to the purpose and is familiar to the developers at EKE-Electronics. Since its development, the process has evolved to form the backbone of critical (SIL) software development at the customer, that can be re-used from project to project.

“The collaboration with SSF has enabled us to successfully expand our offering to safety critical systems on board railway rolling stock. The SSF Professionals have always accomplished their tasks in a reliable an timely manner”, says Jyrki Keurulainen, CTO of Eke-Electronics.

Bepicolombo

BepiColombo is a European Space Agency mission to Mercury. The spacecraft will operate in Mercury’s orbit for at least one Earth year, and study and understand the composition, geophysics, atmosphere, magnetosphere, and history of Mercury.

SSF has developed on-board software (OBSW) for the combined data processing unit (DPU) of the Solar Intensity X-ray and particle Spectrometer (SIXS) and Mercury Imaging X-ray Spectrometer (MIXS) instruments. SSF was also responsible for systems engineering of the data processing unit. SSF continues to maintain the software during the ongoing mission. OBSW design process followed ESA’s strict standards and guidelines including coding standards and documentation. A worst case schedulability and full failure detection, isolation, and recovery were proven during the design. To verify the full functional compliance with the requirements, OBSW functionalities were tested with 100 % coverage.

STUK

The electrical and automation systems department at STUK – the Radiation and Nuclear Safety Authority in Finland, is in charge of overseeing the safety of the instrumentation and control (I&C) systems in Finnish nuclear power plants. STUK oversees regulatory requirements on architecture of such systems, their qualification for use and their design process, necessitating the need for third party independent experts qualified for assessing the critical I&C systems.

SSF has supported STUK as independent experts on I&C safety: SSF has assisted STUK in audits of suppliers of I&C systems, checking compliance to the applicable standards, analysing the adequacy of software design and testing documentation, and evaluating the appropriateness of quality management and quality process documentation. Although the appropriate competence for the assessment is important, equally important has been SSF’s successful and efficient project execution.

NASA

SSF has developed the ground station software for the OMI instrument located on-board the EOS-Aura satellite. The SW consists of a control SW and several data processing programs. The control SW is operated through a graphical user interface and it controls the data processing at the ground station. The data processing is distributed to several computer nodes in order to reach performance that is sufficient for near real time product generation. Currently, the SW system is operational and produces near real time products including ozone column and Ultraviolet-B maps. In addition to NASA’s OMI Control Software, SSF was the Product Generation Environment (PGE) contractor for OMI Processing Centres. SSF has developed the Ozone, NO2, Cloud, Aerosol and O3Profile PGEs that generates the Level 2 vertical column product from OMI level 1b products.

Revenio Group

SSF had the pleasure of helping Revenio Group in developing their new asthma diagnosis product, Ventica. Ventica uses a novel non-invasive approach for identifying airway obstructions in even very young patients. It works by collecting respiration data from the patient while they are sleeping.

The measurements performed by Ventica are based on skin contact electrodes, which means that the signal integrity may be easily disrupted. Common causes are for instance the patient turning in bed, coughing or talking. It is also possible that an electrode becomes disconnected during the measurement. All these disruptions needed to be detected by the algorithm and removed from the analysis data. During development, SSF also implemented a fast raw data parser in MATLAB for importing the raw data from the measurement hardware.

Orion Diagnostica

SSF has acted as a software partner for Orion Diagnostica since 2012. Among others, SSF has supported in the maintenance and development of a software tools used in QuikRead go® and Orion GenRead® instruments.

“SSF has demonstrated excellence, flexibility and technical competence. With SSF, the collaboration is easy and the outputs are meeting the quality and schedule requirements. SSF has proven their value as trustworthy software developer. At Orion Diagnostica we value commitment and high quality. Therefore we are very pleased with our collaboration with SSF”, says Ossi Korhonen, R&D Manager in Instrument Development & LCM, at Orion Diagnostica.

PLATO

PLATO is a European Space Agency space telescope that aims to discover and characterize potentially habitable exoplanets and their parent stars. The telescope will be positioned to the Sun-Earth Lagrange 2 point. This keeps the Sun and Earth approximately toward the same direction as viewed from the telescope, simplifying sun shielding and calibrations. From this position, PLATO will study between 300,000 to 1 million stars and their potential planets. PLATO is planned to be launched in 2026.

SSF is in charge of developing the Spacecraft Control Software (SCSW) of PLATO. SCSW will control the operations, orbit, attitude and temperature of the spacecraft. To ensure quality of the SCSW, SSF is also developing a Software Validation Facility (SVF) for the SCSW. The SVF functions as a “digital twin” of the spacecraft, allowing engineers to exhaustively test the SCSW before its integration to the spacecraft.

Airbus

SSF has acted as a systems and software engineering supplier for Airbus in Germany, UK and France. SSF has provided entire on-board software solutions as well as data processing solutions and engineering support for the most fascinating space missions Airbus has coordinated throughout the years: GOCE, ExoMars Rover, BepiColombo, Sentinel-4/5, Gaia. Today, SSF is also part of the Airbus supply chain by acting as a Tier 2 supplier via Ferchau and Philotech in Germany.

Thales Alenia Space

SSF acts as an on-board software supplier for Thales Alenia Space, and also has a role in a number of operational data processing systems development. Currently, SSF’s responsibility is to design and develop, together with its subcontractors, the satellite control software for the PLATO mission. Previously, SSF has had a major role as the flight software provider for missions such as Herschel and Planck. SSF has been also in the recent years building the instrument software for Flexible Combined Imager and Infra-Red Sounder satellites as part of Meteosat Third Generation series.

Vaisala

SSF participates in Vaisala’s R&D work concerning a variety of product lines and works together with Vaisala with the most innovative and challenging technologies.

“SSF has been a reliable and trustworthy partner in our systems, software and algorithm development work”, says Ari Alanko, Head of Software, Hardware and User Experience, Weather and Environment, Vaisala. “For Vaisala, who is investing 12% of its turnover to R&D and innovations, having reliable partners that never compromise the quality of the work, is the key to success.”

Finnish Defence Forces

SSF collaborates with the Finnish Defence Forces and surrounding industrial companies in Finland and abroad. Our capabilities in system engineering and safety-critical software development have proven to match to the needs of the defence technology industry.

At SSF, every employee has passed a security clearance and our dedicated IT and working facilities have been ensured to comply with the domain specific security requirements. SSF has been audited for the National Security Auditing Criteria (KATAKRI) by the Finnish Defence Forces.

ExoMars RSI

The 2020 ExoMars Mission is a broad cooperative programme between the European Space Agency (ESA) and the Russian Roscosmos State Enterprse (ROS). The ExoMars mission will deliver a European rover and a Russian surface platform to the surface of Mars. The ExoMars Rover will travel across the Martian surface during its planned 6-month life in search for signs of life. It will collect samples from within surface rocks and from underground to a depth of 2 meters using a drill, and analyse them with next-generation instruments. ExoMars mission will be the first mission to combine the capability to move across the surface and to study Mars at depth, which makes it unique. As software is hard to trust, and with high costs at stake, the Rover cannot be left without any backup. A need to have a mean to keep the mission alive even in case when the software nominally running on the Rover fails has opened the door to SSF as a known provider of highly critical software: The Recovery Software Image (known as RSI) is the ultimate back up software which provides basic functionality to the ground to investigate and maintain the Rover Software. The RSI cannot be “fixed” after launch, yet it has to provide such recover functionality for the Rover Software with greatest reliance. And now, after customer test campaign has been confirmed completed with no RSI problems reported, SSF is proud to declare the project successful. Even though there have been many challenges along the way, they are also great lessons learned for future missions to come and will be gratefully remembered when eventually Rover starts living its life – short for a human – but big and significant for humanity. SSF is happy to be part of this adventure.

Meteosat Third Generation

The Meteosat Third Generation (MTG) programme will replace the current generation of European weather satellites with new ones. It will consist of four imager satellites and two sounder satellites, each carrying two types of weather and atmosphere monitoring instruments. The satellites will provide meteorological data over Europe until the late 2030s. SSF is involved in developing ground processing software for the programme, including data output simulators for each instrument in each satellite type, as well as performance analysis tools for the data produced by the satellites. Key areas in the software development include algorithm development and graphical user interface tools for data analysis. Performance is a critical element of the project, as data from the satellites will be in the order of hundreds of terabytes each day. Within the program, SSF, OHB System Ag and Thales Alenia Space France cooperate in the development of the Instrument Control Unit software for the sounder and imager instruments. TAS-F implements the Execution Platform part of the software, and SSF implements the Application Software part, that implements the instrument-specific functions. Those functions include instrument mode management, equipment configuration, instrument work-plan management, auxiliary data generation, and operational thermal control.
