## Summary

The UK Space Agency has concluded a procurement process for the "OCE STK Orbital Analysis Software," a crucial component for its orbital analysis and mission modelling tasks. This procurement, categorised under the goods in industry-specific software packages, follows a direct procurement method due to the specialised nature of the software, which involves proprietary Ansys technology. The procurement process has reached the award stage, with ST Engineering Antycip Ltd selected as the supplier, as they are the sole authorised reseller of Ansys products in Europe. Located in Didcot, the UK Space Agency's involvement as the buying organisation denotes the central government's public authority category. This contract spans from 15th December 2025 to 14th December 2026, highlighting a significant timeline for interested businesses.

This tender presents a unique opportunity for businesses specialising in high-tech industry-specific software, particularly those with capabilities in supporting proprietary technology like Ansys STK orbital analysis software. Companies engaged in the space sector or those authorised to resell specialised technologies in Europe would find this an exemplary case illustrating the importance of niche markets and technology rights. Opportunities may arise for businesses capable of forming strategic partnerships or securing reseller authorisations, leveraging these agreements to explore further contracts within the space and scientific innovation industries.

## Notice

This direct award provides for Ansys Systems Tool Kit (STK) orbital analysis software, which is proprietary technology developed and owned by Ansys. This software is critical for the Office of the Chief Engineer's orbital analysis and mission modelling activities, underpinning technical assurance for UK Space Agency programmes. All intellectual property rights, including source code and specialised modelling capabilities, are exclusively held by Ansys. ST Engineering Antycip SAS is an authorised reseller for Ansys products in Europe and is the only lawful route for UK Space Agency to procure these licences in the UK. This has been confirmed directly with Ansys Regional Sales Team - no alternative supplier can provide, maintain, or support STK licences without infringing IP rights.
