Mission Objectives:
The Project for On-Board Autonomy (PROBA) is a series of technology demonstration missions of the European Space Agency. The first satellite in the series, PROBA-1, was successfully launched on 22 October 2001, initially for a two-year mission and now operational for five years. PROBA-2 is currently under development, with a planned launch in December 2007. PROBA-2 will continue ESA's validation of new spacecraft technologies while also carrying a scientific payload.
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
Mission Instrumentation:
PROBA-2 has the following spacecraft infrastructure technologies:
- New type of lithium-ion battery
- Advanced data and power management system, containing many new component technologies
- Combined carbon-fibre and aluminium structural panels
- New models of reaction wheels, star trackers and GPS receivers
- Upgraded telecommand system with a decoder largely implemented in software
PROBA-2 has the following scientific instruments:
- Solar observation instruments:
- Lyman-Alpha radiometer (LYRA)
- Sun Watcher using AP-sensors and image Processing (SWAP) experiment
- Plasma measurement instruments:
- Dual Segmented Langmuir Probes (DSLP)
- Thermal plasma measurement unit (TPMU)
- GPS receiver
- Laser retroreflector array
