Unlike the familiar triangulation points which have now largely been abandoned, the fundamental benchmarks are still in use by the Ordnance Survey as passive GPS stations (as mentioned by the modern plaques placed on these monuments by the OS). Indeed, a man from the O.S. was seen only a day or so previously with a GPSr on a tripod measuring this location.
