PROSPECT

Focus and concentration on studying ionospheric models. Implementation service of ionospheric delay correction for satellite navigation and wide-area, local-area augmentation system. A basis paltform for exploring the change rules and physical mechanism of the ionosphere.

To understand the structure and change rules of the ionosphere; To reduce the space environment risk of satellite lauch; To improve the performance of satellite navigation system and radar; To increase the reliability of radio communications; To strengthen early warning and forecasting of earthquake and tsunami.
