BackForwardInstrument:  S/WAVES 

Instrument details
Acronym S/WAVES
Full name STEREO/WAVES
Purpose To obtain unique and critical observations on the generation of Coronal Mass Ejections (CME), their evolution and their interaction with Earth's magnetosphere
Short description There are five radio receivers covering the frequency ranges: 10-40 kHz; 40-160 kHz; 0.125-16 MHz; 32 MHz (fixed frequency); and 250,000 samples/s time series snapshots
Background Part of an instrument complex for solar processes investigation
Scanning Technique Interplanetary space observation from two variable positions along the Earth’s orbit around the Sun in order to implement stereoscopy
Resolution N/A (spatially integrated observation)
Coverage / Cycle Full interplanetary space
Mass Power Data Rate
