The Project for On-Board Autonomy (Proba) is a technology demonstration mission of the European Space Agency, funded within the frame of ESA's General Support Technology Programme. It is managed by ESA??s Control and Data Systems Division within the Department of Electrical Engineering, part of the Directorate for Technical and Operational Support at ESA/ESTEC.
 
Work on the project began in mid-1998 and Proba was successfully launched on 22 October, 2001, initially for a one-year mission.  
Proba objectives
 
The objectives of Proba are:

-in-orbit demonstration and evaluation of new hardware and software
spacecraft technologies

- in-orbit demonstration and evaluation of onboard operational
autonomy

- in-orbit trial and demonstration of Earth observation and space
environment instruments
