Ionospheric Beacon

NSSDCA ID: 1974-089C-01

Mission Name: INTASAT
Principal Investigator:Dr. Jose L. Sagredo


This beacon experiment consisted of a two-frequency (40.0100 and 40.01025 MHz) transmitter, that continuously radiated linearly polarized, stable and unmodulated signals at a minimum power level of 200 mw. The two-beacon monopole antenna, one beacon for each frequency, extended from the top and bottom of the spacecraft along the spacecraft axis. Over 40 experimenters in 21 different countries participated. The experimenters calculated total electron content along the propagation path from satellite to ground and observed ionospheric irregularities and scintillations.
