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.[2][3] The satellite was funded through the ESA's MicroSat program.[4] 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. CHRIS is a hyperspectral system (200 narrow bands) that images at 17 m resolution, while HRC is a monochromatic camera that images visible light at 5 m resolution.[5]
With an initial lifetime of one to two years, the satellite celebrated its 20th year of operations in 2021.[5] On 9 March 2018, it surpassed ERS-2 as ESA's longest operated Earth observation mission of all time.[6]
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.
