Awsome ,Dave!!!! Should you have anything at all about kenneth Evenson, or other Background info, roll in , Dave. Yes , It is the basis of the precision for modern instruments, like gps, It makes it possible to do crossreference on measurements done on a Moonbounced signal, with an accuracy of millimeters, Awsome. Yes , light , it was possible to make an accurate reference, in splitted light bundles, splitted in a prisma, and then re-united. Awsome! Adrie
