PROBA (Project for On-Board Autonomy) is a satellite launched by ISRO in 2001 as part of the ESA's MicroSat program. This small (40×60×80 cm; 95 kg) boxlike system, with solar panel collectors on its surface, has remarkable image-making qualities. It hosts two Earth Observation instruments dubbed CHRIS and HRC. It is a hyperspectral system (200 narrow bands) that image at 30 m, plus three in the visible that have 15 m resolution.

The second satellite in the Proba-series, Proba-2 has been launched on November 2, 2009, together with the SMOS mission. Proba 2 is a 0.6 × 0.6 × 0.8 meter, box-shaped structure weighing 130 kg with two deployable solar panels. It has a total of four instruments; two complementary solar observation instruments dubbed SWAP and LYRA, and two plasma measurement instruments dubbed TPMU and DSLP.

Further planned satellites in the Proba series are the formation flight Proba-3 and Proba-V (Proba Vegetation). They are on-going developments without defined launch dates.
