The e-POP payload consists of eight scientific instruments. Together, they are enabling scientists to explore near-Earth space in greater detail.
Instrument | Description | PI | Scientific Output |
---|---|---|---|
CER | Coherent EM Radio Tomography | Bernhardt | Electron content |
FAI | Fast Auroral Imager | Howarth | Infrared and visible images |
GAP | GPS Attitude and Profiling Experiment | Langley | Spacecraft position and attitude |
IRM | Imaging and Rapid-Scanning Ion Mass Spectrometer | Yau | Low energy ion detection |
MGF | Fluxgate Magnetometer | Miles | 3-D magnetic field and currents |
NMS | Neutral Mass Spectrometer | Hayakawa | 0.1-2km/s neutral particles |
RRI | Radio Receiver Instrument | James | Radio wave propagation |
SEI | Suprathermal Electron Imager | Knudsen | Low energy electron detection |

The e-POP instruments on CASSIOPE
The e-POP instruments are supported by Cascade, the companion commercial payload on CASSIOPE, which permits the on-board storage of up to 75 GB of e-POP data. This data can be downlinked to the ground at a rate of over 300 Mbits/s, allowing the e-POP payload to capture up to 15 GB per day of valuable scientific data.
