Participation of the Holmdel Station in the Telstar Project

l.i Objectives The Holmdel station was originally established in 1959-1960 to carry out communication tests with the passive earth satellite Echo I. A complete description of the station and results obtained during Project Echo are given in Ref. 1. In the summer of 1901 it was decided to take part in the Project Telstar program, and the necessary modifications to the station were begun at that time. The main objective for Holmdel was to receive an acceptable television picture from the Telstar satellite and relay it back to Andover by land routes for comparison with the original picture transmitted from Andover. The Andover station was also expected to receive a television signal, but it was felt that a demonstration of transmission between two separated points would be meaningful. It was not anticipated at the time that the European stations would be ready by the expected launch date. In addition, having two receiving stations would increase the probability of successful operation. Secondary objectives for Holmdel operation were: (a) Measure the 4-gc signal levels to check the satellite transmitted power. 1421
