PROBA(Project for On-Board Autonomy), renamedPROBA-1,is a Belgiansatellitetechnology demonstration mission launched atop an IndianPolar Satellite Launch VehiclebyISROon 22 October 2001.[1][2]The satellite was funded through theESA'sMicroSatand General Study Program with the objective of addressing issues regarding on-board operational autonomy of a generic satellite platform.[3][4]This small (60×60×80 cm; 95 kg) boxlike system, withsolar panelcollectors on its surface, hosts two Earth Observation instruments dubbed CHRIS and HRC. CHRIS is ahyperspectralsystem (200 narrow bands) that images at 17 m resolution, while HRC is a monochromatic camera that imagesvisible lightat 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 surpassedERS-2as ESA's longest operatedEarth observationmission of all time.[6]ESA aims to deorbit the satellite through theClearSpace-1mission in 2026.[7]
Series of satellites[edit]
PROBAis 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 theSMOSsatellite.
The third satellite to be launched wasPROBA-V(PROBA-Vegetation), on 7 May 2013.
Further planned satellites in the PROBA series include the formation flying demonstration missionPROBA-3and limb sounderALTIUS.
