  • The following experiments were carried out.
    • Number density measurement of Electron by Impedance probe (NEI)
      Data (Capacitance, Ne-Ascent / Descent ) / Spectrogram / Ne-Profile
      In order to understand radio wave propagation in the nightside mid-latitude ionosphere, electron number density in a range from 103 to 2x106 /cc is measured along the rocket trajectory by impedance probe.
    • Tracking Data         Data
      Latitude, longitude, and height of the sounding rocket as a function of X, time from the launch. The data file is provided in the text format.
    Data of NEI are archived at DARTS as of Apr. 2021.
