SNOOPI<\/a><\/p>\n\n\n\n

Signals of Opportunity P-band Investigation\uff08SNOOPI\uff09is a 6U CubeSat mission that will demonstrate and validate the in-space use of P-band signals of opportunity to measure root zone soil moisture and snow water equivalent. <\/p>\n<\/div>\n\n\n\n

Wind Speed Retrieval<\/a><\/p>\n\n\n\n

Using the GNSS-R signal we are able to track the ocean surface wind field and provide data on the tropical cyclone at a higher temporal resolution and provide a better understanding of the development of hurricanes and provide a better forecast. <\/p>\n<\/div>\n\n\n\n

Soil Moisture (Tower)<\/a><\/p>\n\n\n\n

Signal of opportunity soil moisture sensing is a remote sensing technique that uses signals from existing communication systems, such as MUOS (Mobile User Objective System), to measure soil moisture content.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Soil Moisture (Air Borne)<\/a><\/p>\n\n\n\n

By placing the receiver onboard a airborne vehicle (piloted plane or drone). We can achieve wide area of sensing with high mobility.<\/p>\n<\/div>\n\n\n\n
