Session 10: A Look Back: Lessons Learned
Abstract
The CubeSat Radiometer Radio Frequency Interference Technology Validation (CubeRRT) mission has developed a 6U CubeSat to demonstrate radio frequency interference (RFI) detection and mitigation technologies for future Earth remote sensing missions. Anthropogenic sources of RFI can degenerate important geophysical retrievals from spaceborne passive microwave radiometers. Real-time on-board RFI processing is therefore an important technology needed for future radiometry missions. CubeRRT will perform microwave radiometry observations in 1 GHz channels tunable from 6-40 GHz and will demonstrate on-board real-time RFI processing. The CubeRRT payload consists of a wideband antenna subsystem developed at Ohio State, a tunable analog radiometer subsystem developed at Goddard Space Flight Center, and a digital backend processor for real-time RFI mitigation developed at the Jet Propulsion Laboratory. The spacecraft bus was developed and integrated at Blue Canyon Technologies. The enabling CubeRRT technology is a digital Field-Programmable Gate Array-based spectrometer with 1 GHz bandwidth that implements advanced RFI filtering algorithms based on real-time kurtosis and cross-frequency techniques. CubeRRT was manifested on the OA-9 International Space Station resupply mission and launched on May 21, 2018. This talk will describe the assembly and test of the flight system as well as the status of on-orbit operations.
