Current Projects
Possible use of constellation of cubesats to monitor and issue warnings of tsunami in progress with GNSS reflectometry and analysis of ionospheric perturbations caused by upward travelling pressure waves generareted by tsunami.
Remote Sensing
As indicated in the title. Also looking for possible secondary use of cubesat constellation to monitor climate change through observation of the tropospheric water vapor content and the ionosphere using the same =data for detecting tsunami.
