CubeRRT (CubeSat Radiometer Radio Frequency Interface Technology) is a technology demonstration mission by the Ohio State University that will validate advanced technologies for Earth remote sensing in space by conducting radiometer radio frequency interference technology validation.

It is a space-borne technology readiness level seven demonstration of real-time mitigation of radio frequency interference.

The Ohio State University, will lead the development of CubeRRT, a project to observe, detect, and mitigate radio frequency interference (RFI) for microwave radiometers, an instrument that measures Earth’s properties, including atmospheric water vapor or soil moisture. RFI is a growing problem in radiometry due to increasing demand for use on the spectrum for communications. If successful, CubeRRT technologies will address gaps in existing RFI mitigation technologies to increase the amount of high quality radiometer data collected by future Earth observing missions.

CubeRRT is built on a 6U CubeSat bus built by Blue Canyon Technologies.

It was selected in 2016 by NASA's CubeSat Launch Initiative (CSLI) program by the CubeSat Launch Initiative (CSLI) to be launched as part of the ELaNa program. It was launched on the ELaNa-23 mission on board of Cygnus CRS-9 to the ISS, where it was deployed on 13 July 2018 via the JEM airlock.
