PROBA (Project for On-Board Autonomy), renamed PROBA-1, is a Belgian satellite launched atop an Indian Polar Satellite Launch Vehicle by ISRO on 22 October 2001. The satellite was funded through the ESA's MicroSat program[1]. This small (60×60×80 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.

With an initial lifetime of 1 to 2 years, the satellite celebrated its 16th year of operations in 2017. On 9 March 2018, it surpassed ERS-2 as ESA’s longest operated Earth observation mission of all time[2].

Series of satellites

PROBA is also the name of the series of satellites starting with PROBA-1. The name is also used to refer to the bus of the satellites.

The second satellite in the PROBA series, PROBA-2, was launched on 2 November 2009 together with the SMOS satellite.

The third satellite to be launched was PROBA-V (PROBA-Vegetation), on 7 May 2013.

Further planned satellites in the PROBA series include the formation flying demonstration mission PROBA-3 and limb sounder ALTIUS.
