Innovative Services Beyond Tomorrow

Satellite assets are essential elements for numerous everyday life services, such as geoinformatics, mapping, resource utilization, positioning, weather forecasting and communications. Huld has participated in projects ranging from ice coverage analysis to forest fire detection, and from improved positioning to algae monitoring. In fact, current everyday life is fulfilled with data that is derived from satellites – navigation, rain forecasts and internet applications.  

As these applications are so vast and touching almost everyone, it is utmost important to have satellites working flawlessly. Huld’s in-house expertise lies precisely on these demanding space applications, concerning real-time software in the satellite’s payload and platform. The design process of the complex data processing systems, instrument data simulators and test facilities are in the core of our space industry competencies. That we have been doing since 1989 in more than 150 ESA projects, working previously under the name Space Systems Finland (SSF), and since 2020 by the name Huld. 


On-Board Software Development

Huld has provided software solutions to numerous satellites ranging from Envisat to the International Space Station. We provide mission-critical control systems to satellite platforms, and scientific processing in atmospheric sounding and imaging missions. Key element is safety-critical, tested and validated software, able to function years in harsh space environment. 

Huld has provided platform software to GOCE, Herschel, Planck and Gaia satellites. In addition, our software is bound to planet Mercury and Mars. Latest references in application software segment are on board MetOp-SG (ROIC, 3MI, SCA), ExoMars RSI, Euclid FGS, MTG FCI ICU ASW, Sentinel-4 ICU, Galileo ASW and MetOp CFSW. 


Data Processing and Instrument Quality Tools

We have worked in the field of satellite data ground processing since 1989, from the ENVISAT mission development. Since that, the categorization of different satellite data products has led us to specialize in certain phases and tools of the data products. 

Huld has developed a L1b prototype data processing software for European Copernicus mission in Sentinel-4 and Sentinel-5 missions. In addition, we have worked in L2 operational processor in MTG imager and sounder. The Instrument Quality Tool, IQT, allows the assessment of the geometrical and radiometric performances of the instruments on-board both MTG Imager and Sounder satellites, thus acting as a quality and performance tool. The Ground Processor Prototype (GPP) provides aid in the development of the operational instrument processor for the EUMETSAT ground segment. The GPP will also be used to demonstrate the performance of the instrument and the level 1b algorithms during on-ground and in-orbit tests. 


Independent Software Verification and Validation (ISVV)

Our long experience in development of high-reliability software has laid a foundation to act as external consultant assisting prime companies to ensure the quality of a software product developed by software subcontractor. Presently, one of the key expertise areas of Huld is ISVV. We have conducted Independent Software Verification and Validation for multiple space on-board software: The European Data Relay System (EDRS), the Meteosat Third Generation (MTG) including MTG’s Strat Tracker instrument, the ESA Mercury mission BepiColombo platform software, the Small geo-stationary (SGEO) satellite, Integral mission, and five major units of the European satellite navigation system Galileo flight segment. 


New Space

Huld’s NewSpace capabilities build on the 30 years’ ESA space experience, combined with the industrial needs for SW development schedule, Continuous Integration  / Continuous  Development (CI/CD) and Systems Engineering. Huld has participated now in several CubeSat, SmallSat and Space-based-Service projects either in SW/Systems Assessment, Technology Study or as an outsourced engineer for SW and HW. This is also the offering for your business; our Customer has the technology driver and service idea, and we have the technology and capacity to help you! 


Space Based MIL Systems

Huld Defence builds upon our decades long systems engineering experience derived from implementing mission critical space solutions. This combined with our data analytics and machine learning expertise allows us to develop, deliver and maintain capabilities for land, air and sea defence systems. 

Our capabilities focus in: 

  • Software and systems engineering for various military applications 
  • Data fusion and algorithm development for test systems and measurement instruments 
  • Data analytics for reconnaissance sensors 
  • Machine learning assisted situational awareness and targeting, including non-GNSS navigation capabilities 

Huld has been working with the defence projects since 2007, and has a Facility Security Clearance (FSC).
