Opportunities for HF Radio Science using the RRI on Swarm-E and the ongoing work at USASK

Swarm-E, previously known as CASSIOPE is a Canadian small satellite mission carrying the enhanced Polar Outflow Probe (e-POP) scientific suite. One of the eight instruments on e-POP is the Radio Receiver Instrument (RRI), which was designed to study the physics of radio wave propagation, and the generation of spontaneous radio emissions created by auroral processes. RRI is a digital receiver that is capable of measuring radio waves in the frequency range of 10 Hz to 18 MHz with the aid of its two orthogonal 6-m dipoles. By measuring the properties of transionospheric radio waves, researchers can better understand the behavior of the ionosphere and its impact on radio wave polarization characteristics. This talk will specifically focus on the coordinated experiments between RRI and ground transmitters in the HF band, and what we have learned from them as the RRI group at USASK.
