Estimation of the Parameters of Nuclear Explosion based on GNSS Observation

Acoustic-gravity wave induced by underground nuclear explosion will affect the ionosphere by generating travelling ionospheric disturbance (TID). Such effect can be studied by GNSS observation and the parameters of nuclear explosion can be calculated as well. Based on GPS data from several IGS stations, methods used for estimation of TID velocity and source location have been studied and the result confirms the feasibility of estimating the source location by GPS observations.
