Resources & Tools
Discover how we’re driving innovation for safer navigation
GRAD has developed several software tools, ranging from radionavigation system coverage models (LF, MF, VHF) through to software to help define the number of solar panels and batteries needed when re-engineering a lighthouse.
These tools were developed to help our GLA colleagues, who can access them via the portal. However, we do provide commercial services should any of these tools or services be of interest to 3rd parties – please contact us to know more.
Example tools offered by GRAD:
Visual Signalling
Lighthouse Performance Estimation Calculator (LiPEC)
This tool supports our engineering colleagues by offering guidance on the expected performance of lamp and lens combinations.
Astragal Obscuration Calculator
The astragal (bar across the lantern room windows in a lighthouse) can affect the amount of observed light. This tool models the impact given specific design characteristics for that location.
Calculator for AtoN Light Performance (CALP)
Tool to convert the navigational requirements needed for the AtoN, into the engineering requirements for our GLA colleagues to deliver the required service.
Radionavigation
Radionavigation coverage modelling software
We can model the expected coverage region and performance metrics for many different radionavigation systems including eLoran, DGNSS, AIS, VDES, radar etc.
GNSS & eLoran Monitoring
We monitor GNSS/eLoran performance from different parts of the GLA estate and can play back this data to investigate performance and any reported anomalies.
Solar energy
GLA Solar Energy Calculator (GSEC)
This tool supports engineers in identifying the required solar panels and batteries for a given power demand of a designed lighthouse/buoy.
Digital services
GLA eNavigation & digital Service Architecture Testbed
A prototype system to exchange GLA AtoN information in the latest S100/S200 product specifications.
Tri-GLA VDES authentication testbed
VDES testbed across the GLA estate, used to test and demonstrate future VDES AtoN services including securing AtoN information through authentication.
AI use of AtoN
Digital buoy data set
To support research in how our AtoN are observed by autonomous vessels, we have created a tool to generate training images of maritime buoyage.
Training
GRAD offer the following training courses to our GLA colleagues:
Essential Lights Awareness Training (ELAT)
Introduction to light terminology, lighthouses lanterns and lens systems.
Visual Signalling Designers Course (VSDC)
A more detailed look at designing and specifying lighthouse lanterns and lens systems, in support of lighthouse re-engineering projects.
