e-POP Payload on CASSIOPE

The e-POP payload consists of eight scientific instruments that will aid in reaching the project's scientific goals:

Instrument	Description	PI	Scientific Output
CER	Coherent EM Radio Tomography	Bernhardt	Electron content
FAI	Fast Auroral Imager	Cogger	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	Wallis	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 will be 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.

The animation below shows the simulated orbit trajectory of one day of e-POP operation (14 orbits). The payload will be able to sample a large set of local times, and all latitudes below 80°.
