MIDDLESEX, England, Oct. 5, 2009 – The National Physical Laboratory (NPL) has helped to establish that femtosecond comb lasers can provide accurate measurement of absolute distance in formation flying space missions. NPL, along with collaborators, produced technical reports for the European Space Agency. The conclusions demonstrated that the lasers were a suitable method for measurement in such missions. Formation flying missions involve multiple spacecrafts flying between tens and hundreds of meters apart, which autonomously control their position relative to each other. The benefit of such missions is they can gather...Read full article
