China is planning the construction of a new "global occultation meteorological detection constellation" for gathering high-precision meteorological data based on the interpretation of signals beamed down from satellites, according to CASIC's 2nd Institute. The system will measure the frequency, phase and amplitude of signals transmitted by navigation satellites, recording how they change after passing through the ionosphere and atmosphere. The resulting data will allow meteorologists to calculate the temperature, humidity and pressure of the atmosphere, as well as the ionospheric electron density.
