definition: Proba-1 payloads Proba-1 carries onboard several Earth observation and space environment scientific instruments. In view of the project’s aim to demonstrate technology, several platform elements and systems have also been included as technology experiments. The Proba-1 development approach includes several innovative aspects. A design-to-cost approach was adopted according to European Cooperation for Space Standardisation category 3 project classification. This involved using COTS (commercial off-the-shelf) equipment and units; simulation-based development, verification and testing; automated software generation; extensive use of test and operations infrastructure commonalities; and a highly integrated ESA-industry design and development team. Extensive use is made of automated functions onboard the spacecraft. Full onboard flight dynamics computation, in conjunction with automated ground segment functions such as pass automation and high-level user interfaces, satisfy the spacecraft autonomy requirements. Automated functions onboard handle nominal spacecraft operations, plan and schedule activities, and manage payload resources. Onboard flight dynamics include orbital navigation as well as computation and control of instruments, camera pointing and scanning in order to meet user-defined targets (latitude, longitude and altitude).
