Yes, wouldn't take much to have the thing work in reverse. Accuracy also would depend on how accurate the tilt sensors are, etc. The Navy and Air Force have had such devices for quite a while. It also wouldn't be much of a stretch to add lunars. There accuracy would take a dive, I expect. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to NavList@fer3.com To , send email to NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
