The SPICAV instrument is derived from the SPICAM instrument onboard Mars-Express.
Both instruments provide two channels:

  • A channel for the ultraviolet range ---- SPICAV-UV (SUV)
  • A channel for the infrared range ---- SPICAV-IR

In order to observe the Sun absorbed by the Venus atmosphere in the infrared between 1.8µm - 4µm, SPICAV uses a third channel:

  • SOIR, Solar Occultation in the Infrared

SOIR is a completely Belgian instrument. It has been built at the Belgian Institute for Space Aeronomy in close cooperation with two Belgian industrial partners: OIP and PEDEO.
