The e-POP payload consists of eight scientific instruments that aid in reaching the project's scientific goals:
|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 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.
The animation below shows the orbit trajectory of one day of e-POP operation (14 orbits). The payload is able to sample a large set of local times, and all latitudes below 81°.
