## Summary

The procurement process, led by the Department for Science, Innovation & Technology, involved a contract titled "Development of the mathematical models for eLORAN groundwave and skywave propagation." This project falls under the navigation equipment category and is located in the United Kingdom, specifically at the department's headquarters in London. The process has reached the award stage, with a contract period set to start on 3rd March 2026 and conclude on 31st March 2026. The procurement method used was a direct award due to the specialised nature of the project. Cambridge University Technical Services Limited (CUTS) has been selected as the supplier to develop these advanced mathematical models, focusing on the complexities of groundwave and skywave interactions.

This tender presents significant business growth opportunities for companies with expertise in sophisticated mathematical modelling and electromagnetic RF propagation. Businesses well-suited to compete would typically possess specialised knowledge in navigation equipment and scenarios requiring intricate understanding of wave dynamics, such as in multi-layer environments. The contract value is £99,000, making it an attractive proposition for large-scale service providers who can leverage their expertise in meeting the unique requirements of the Department for Science, Innovation & Technology.

## Notice

Funded research project to develop advanced mathematical models for eLoran signal propagation, focusing on; the overlap zone (where ground and sky wave signals mix) and multi-layer environments (e.g., ice and seawater).

### Procurement Information

Extensive research was conducted for alternative sources. Mathematical modelling is ubiquitous in the marketplace, however the specific type required is quite specialised. Other sources considered have none of have the combined expertise in mathematic modelling of RF (Radio Frequency) propagation. Other groups considered have experience in wave dynamics and propagation, but do not have experience with electromagnetic modelling.
