This article contains orbital elements but does not include an epoch, or date when those elements, which typically vary over time, were correct. Please help by adding the epoch for the current data, or changing the orbital elements to ones with a known epoch. Unsourced materials may be challenged and removed.
PROBA (Project for On-Board Autonomy) was a Belgian satellite launched atop an Indian Polar Satellite Launch Vehicle by ISRO in 2001. The satellite was funded through 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 was launched on November 2, 2009, together with the SMOS mission. 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.
Payloads are separated by bullets ( · ), launches by pipes ( | ). Manned flights are indicated in bold text. Uncatalogued launch failures are listed in italics. Payloads deployed from other spacecraft are denoted in brackets.
