in depth F6 project DARPA's programme takes a modular approach

摘要

The F6 project run by the US Defense Advanced Research Projects Agency (DARPA) aims to form a virtual satellite by using clusters of what it calls 'fractionated space modules'. Each module is expected to have a unique capability, such as navigation, payload and data handling, and can either be physically connected in orbit, or linked together through a wireless network. According to DARPA, because the various functions of a spacecraft are developed and launched separately, the overall programme risk will be reduced, budgetary and planning flexibility will be increased and the initial speed of deployment can be improved. The organisation is hoping for a planned flight demonstration of the F6 programme sometime in 2013-14.
