AAUSAT5 is an educational mission for students, built by students. Its main objective is to provide university (bachelor and master) students with significant practical experience in the full lifecycle of a real, challenging, space project. Students are given the opportunity to combine theory and practice, acquire project management experience, and adopt procedures that are typical of real-life space missions. Through this experience, the students have the opportunity to form international networks within the space community, and to develop technical and interpersonal skills applicable to their future careers.
The educational mission is achieved through the accomplishment of the specific technical objectives set for AAUSAT5: toconduct, in-orbit, testing of an improved version of the Automated Identification System (AIS) receiver. The AIS is a system developed to track and identify ships and other vehicles carrying an AIS transponder, which are transiting away from coastal areas and in remote areas, that will help to enable safe use of new sea shipping lanes.
AAUSAT5 follows its predecessors, AAUSAT3 and AAUSAT4, with additional features to allow for its deployment from the ISS into low Earth orbit. The low altitude gives a smaller foot-print and higher signal strength when receiving AIS signals from ships, which will broaden the opportunity for testing AIS in areas with high density shipping, such as Europe. AAUSAT5 is expected to be operational for approximately 3 to 8 months.
