Paper Abstract

Knowledge of the instantaneous state of the ionosphere can facilitate many components of C3I systems. Traditionally, ionospheric measurements have been performed using Langmuir probes, ion mass spectrometers, radars and ionosondes. The first two sample the ionosphere in situ, along the rocket or satellite trajectories. Besides being an active probing method, ground-based radio observa-tions are limited to a geographically fixed area surrounding the measurement site. In recent years it has been shown that ionospheric density distributions can be obtained by the remote sensing of selected Extreme Ultraviolet (EUV) emissions. The sensors for these measurements employ space-based passive detection techniques. The spectral region below 2000 A has successfully been used to both probe the upper atmosphere and image the aurora, even under fully sunlit conditions. The EUV measurements can also be used to infer the energy of precipitating electrons in aurorae. In this paper recent work in these areas will be reviewed. Requirements for future instrumentations will be discussed.
