Replacement of Light Measurement Data Acquisition Hardware for Marine Navigation Testing

Trinity House's GRAD facility in Harwich operates a light measurement laboratory that has served the General Lighthouse Authorities (GLA) of the UK and Ireland for decades. The facility conducts independent testing of marine aids-to-navigation lights to verify their suitability and maintains a comprehensive database of performance measurements for optical systems installed at lighthouses. The current data acquisition hardware that forms the core of this semi-automatic light measurement process is obsolete and no longer supported by the manufacturer. An alternative or replacement system is required to maintain testing capability and ensure continued support for the GLA's mission of marine safety. Suppliers should understand that this is mission-critical equipment requiring reliable, accurate performance for specialized light measurement applications in a marine navigation context.
