SNoOPI
SNoOPI [Purdue University]
The SNoOPI (SigNals of Opportunity P-band Investigation) is a 6U CubeSat scientific investigation mission to demonstrate the measurement of the complex reflection coefficient over various land surface conditions for use in future CubeSat constellations by Purdue University, West Lafayette.
The technology will measure snow and soil moisture, which are vital data for applications like food security and water resources management. SNoOPI will be the first on-orbit demonstration of the P-band signals of opportunity technique and will advance the prototype instrument to Technology Readiness Level 7.
It was selected in 2019 by NASA's CubeSat Launch Initiative (CSLI) to be launched as part of the ELaNa program. The satellite is to be launched onboard of Dragon CRS-27 towards the ISS, from where it will be deployed.
