RKF is the Technical Pillar for Wireless Communications for the DARPA Tactical Technology Office (TTO) F6 program.  The goal of the System F6 program is to demonstrate a radically new space system composed of a heterogeneous network of flying or loosely connected small satellite modules that will, working together, provide at least the same effective mission capability of a large monolithic satellite.  This fractionated space system offers the potential for reduced risk, greater flexibility (e.g. simplified on-orbit servicing, reconfigurability to meet changing mission needs), payload isolation, faster deployment of initial capability, and potential for improved survivability.  RKF is responsible for ensuring that communications between modules and between modules and the ground is sufficient to meet current and future mission needs.
