Opportunity overview
Based within Trinity House in Harwich, GRAD has been operating a light measurement facility for the purpose of testing marine aids-to-navigation lights for the General Lighthouse Authorities of the UK and Ireland (GLA) for many decades. The facility provides the GLA with the ability to independently determine the suitability of lights for aids-to-navigation purposes, as well as building a unique database of performance measurements of lights in optical systems installed at lighthouses.
The measurement systems and processes employed are relatively simple, but working together, they form a sophisticated semi-automatic light measurement process.
The data acquisition hardware at the heart of the measurement processes is the same for all facilities, but it is no longer supported by the manufacturer. This is a fundamental piece of equipment in the measurement process and a replacement is needed.
