As such, it is envisaged that visual or near-visual signalling will continue to be an important part of the resilient positioning and navigation solution at sea. R&RNAV has two projects that require the engagement of services of an external, authoritative, maritime navigation expert for additional support in providing a summary of the state-of-the-art in the visual signalling and machine vision technologies. Additional information: The contracting authority considers that this contract may be suitable for economic operators that are small or medium enterprises (SMEs). However, any selection of tenderers will be based solely on the criteria set out for the procurement. ## CPV classification Navigation services Source Contracts Finder (UK) [View official notice](https://www.contractsfinder.service.gov.uk/notice/e3babcbf-27ba-42d9-a9e4-5a19c9e16f08) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
