Preferred term

MMIA  

Definition

  • ASIM uses optical observiations in carefully selected bands in order to filter out data with TLEs from the lightning data. Since downlink is limited, thse algorithms are implemented in the on-board software. The ASIM MMIA instrument is capable of observing 12 frames per second continuously in the 777.4 nm and 337 nm bands, both only 5 nm wide. Combined with 100 kHz photometer data from the same two bands in addition to a 180-230 nm band, data is filtered en realtime to optimize the available downlink capability allocated to ASIM on ISS.
