Abstract

A first time transfer experiment using an infrared laser link and flyover was performed in November 1977 between the Paris and San Fernando (Spain) observatories. This experiment follows from a cooperative effort of several French and Spanish organizations (Besson, 1970; Benavente et al., 1977). Equipment to be used in the operation was developed independently by the participating organizations, and a brief description of the system is given, along with a presentation of the organization of the whole operation. From a study of the data obtained, one can appreciate the feasibility and capabilities of the method employed. The final result is the comparison of the UTC scales of the Paris and San Fernando observatories.
