Electron Content-Beacon

NSSDCA ID: 1964-084A-02

Mission Name: San Marco 1
Principal Investigator:Prof. V. Carrara

Description

The ionospheric beacon experiment consisted of a high-frequency radio transmitter that operated on command, with 670 mw of power and at a frequency of 20.005 mHz. A 0.01-mHz keyed frequency shift was provided for positive signal recognition. The transmitting antenna was a retractable 5-m (tip to tip) dipole that was oriented along the spacecraft spin axis. The antenna was retracted during operation of the drag experiment in order to provide a better drag cross section. The experiment was operated from about December 31, 1964, to January 13, 1965, and obtained 2068 min of beacon transmissions.
