Tri-Band Beacon

The Tri-Band Beacon is a three-frequency radio beacon developed to provide transmission at VHF/UHF and L-band (150/400/1067 MHz). The primary objective of the Tri-Band beacon is to study the electron density in the ionosphere and to produce two-dimensional maps or one-dimensional profiles. The secondary objective is to measure the influence of ionospheric irregularities on VHF, UHF and L-band transmissions from space to ground.
