Abstract
The Office National d\´Ã‰tudes et de Recherches Aérospatiales has devised a method of time synchronization by what is described as "simple overflight," relying on a high-precision airborne timepiece, without the need to go close to the clocks under comparison. The method has repeatedly been tested, and the results show the accuracy of synchronization to be better than 50 ns. A comparative experiment between the observatories of Paris, France, Hailsham, England, Ottawa, Canada, and Washington, D. C. will be carried out in September 1970.
