Description
ALTIUS is an original, groundbreaking mission which answers pressing questions and needs within the atmospheric remote sounding community. The project was proposed by the Belgian Institute for Space Aeronomy (BISA) and it is presently implemented as an element of the ESA Earth Watch program. The data processing algorithms will be developed in a collaboration between BISA, the University of Saskatchewan and the industry. Ozone and aerosol stratospheric profiles are the main operational objectives of the mission.
The truly innovative technology being developed through ALTIUS resides in the use of a high-performance microsatellite of the PROBA class that can operate in a multi-mode approach. Starting from a well-stabilized and controlled platform attitude, a single sensor can be optimized for a combination of limb scattering measurements and solar, stellar, and planetary occultations. The combination of an imager with an accurate attitude control allows for determining the tangent altitude by relating the instrument field of view to the satellite attitude.
We will present the baseline algorithm that will be implemented to retrieve the near-real-time operational ozone product.
