Objectives and Applications
PROBA is a technology experiment to demonstrate the on-board autonomy of a generic platform suitable for small scientific or application missions. A number of earth observation instruments are included. CHRIS - a hyperspectral imager provides data related to Earth Resources science and applications.

Proba-1 CHRIS Level 1A Full Archive
Jan-2001 | Intended as a one-year mission, Proba-1 was launched on the 22nd of October 2001
and since 2004 has been managed by ESA’s Ground Segment Department within
the Directorate of Earth Observation at ESA/ESRIN. While it remains an ESA mission,
Proba-1 is funded as a TPM and its data are distributed using the mechanism of the
TPM scheme. Proba-1 carries a Compact High-Resolution Imaging Spectrometer (CHRIS) – the only
currently operational European spectrometer with contiguous bands and multi-angle
acquisition capability ESA offers access to worldwide Proba-1 CHRIS data (both archived and new acquisitions) via the TPM scheme. - Read more |
