Full Name Fast Auroral Imager Status Operational
Instrument Agencies CSA Maturity
Instrument Type Space environment Geometry
Instrument Technology Space environment monitor Sampling Other
Data Access Open Access Data Format
Measurements and Applications Measures the large-scale auroral emissions in the 630-1100 nm wavelength range. The FAI imager system produces 16-bit digital images of the near infrared band at one image per second (CASSIOPE is a 3-axis stabilized platform),and the 630-nm wavelength at two images per minute, giving adequate temporal resolution to investigate the above scientific objectives.
