Microsferics Time of Difference of Arrival Display The TDoA (Time of Difference of Arrival) system is a network based lightning triangulation method employing multiple volunteer detection sites across Europe and North America. It provides high accuracy detection which augments the participating stations existing Boltek lightning detection systems. Headcorn Weather is part of this project and supplies data to the TDoA network. The technology utilises the highly stable and immensly accurate GPS timestamp to tag each potential lightning strike which is then mathematically analysed and passed along to a central server where it is subject to further analysis and matching with other detection signatures from alternate stations. When 4 or more stations confirm the same strike it is recorded along with its type (+/- CG or IC) and made available for display, in the above case on a composite vector map with frequent updates. Theoretical accuracy is dependant on the number of stations detecting the strike and the geometry of those stations in relation to the strike itself, however in theory this is between a few Kilometres down to just a few hundred metres which is quite impressive. Further details can be found in the Microsferics How It Works Guide. Our display software is in beta with frequent updates.
