The Coherent Electromagnetic Radio Tomography (CERTO) is a radio beacon which measures ionospheric parameters in coordination with ground receivers.
CERTO provides global ionospheric maps to aid prediction of radio wave scattering.
CERTO was developed by the Naval Research Lab and is one of the 4 experiment packages aboard the PicoSAT satellite.
