2 System F6 Summary The System F6 program is developing technologies for fractionated spacecraft architectures. The key potentially transitionable elements of our research will be the F6 Developer s Kit (FDK) and the F6 Technical Package (F6TP). Four ESPA-size spacecraft will fly a demo mission in to demonstrate the capability of a fractionation. 2

3 System F6 and Fractionated Architectures A Quick Synopsis Fractionation a subset of disaggregation, wherein the functionality provided by a single, large, monolithic satellite is delivered by that cluster of wirelessly networked modules and other networked nodes sharing a variety of software and hardware resources. System F6 A Defense Advanced Research Projects Agency (DARPA) program that is developing and will demonstrate the enabling technologies for fractionated spacecraft architectures. Purpose of Fractionation - significantly enhance the adaptability and survivability of space capabilities while shortening development timelines for complex space systems and reducing the barrier-to-entry for participation in the space industry. 3

4 An F6-Enabled Spacecraft Shared Resource F6TP Wireless Inter- Module Transceiver The F6 Technology Package (F6TP) running F6 Developer s Kit (FDK) specified software will enable a spacecraft to become part of a fractionated network. 4

5 Key Program Elements F6 Developer s Kit (FDK) everything needed for an independent third party to develop a module that can fully participate in a fractionated cluster. F6 Technology Package (F6TP) low cost, commercialized physical instantiation of the FDK that will enable a spacecraft bus to become a fractionated cluster module. F6 On-Orbit Demo Test Bed (F6 OOTB) spacecraft buses, shared payload devices, and associated components and services to demonstrate the System F6 concepts on-orbit in Value Centric Architecting and Design (VCAD) Tools A toolset that will enable automated design and tradespace exploration of a wide variety of conventional, disaggregated, and fractionated systems. 5

6 The F6 Developer s Kit (FDK) Modeled after a software developer s kit (SDK). The FDK is: set of open source interface standards, protocols, software, behaviors, and reference implementations Enables any party or person to develop and integrate element(s) of a F6 System, including, but not limited to apps, payloads, peripherals (e.g., radios), modules, and/or ground systems. The FDK is not proprietary to any single vendor. 6

7 The F6 Developer s Kit (FDK) Performers Cluster Flight Application (CFA): Emergent Space Technologies Cluster control algorithms. Bus agnostic. Information Architecture Platform (IAP): Vanderbilt University A MLS capable operating system Includes CORBA and DDS Middleware F6 Wireless Intermodule Communications (F6WICS) K-band +TDMA (SWRi) and S-band, V-band (Aeronix) Radios 7

8 F6 Technology Package (F6TP) A network-computing device that will physically connect to and provide switching and routing functions between: the spacecraft bus, one or more wireless inter-module transceivers, shared resource(s) and, mission payloads such as mission sensors (including hosted payloads). Runs the FDK standards-based information architecture software. Cryptographic acceleration hardware is a part of the F6TP design. BAA required SWaP: Size <3000 cm 2 Mass Power < 5kg < 15W/30W (Avg/Peak) 8

9 F6 Technology Package (F6TP) Performers Three industry performers are currently being placed on contract to design and produce at least one F6TP. A DARPA IDIQ will provide contractual ease in procurement if produced in volume. Multiple performers have been selected. 9

17 The FDK and F6TP used for Hosted Payloads The FDK and F6TP will be able to serve as a hosted payload interface standard and unit, respectively Common physical data interface standard connections (e.g., Spacewire, Ethernet). IP enabled that allows a migration path toward a common ground network standard. Common serial interface standards and software API s readily allow interface to most if not all commercial and NSS spacecraft buses. Software encryption/future MLS maximizing information assurance of secure payloads. App-centric software construct allows modular construction of hosted payload processing and mission management task. The latter is important as it allows arbitration of bus services to the hosted payload during operations. Fault management architecture includes layered anomaly detection, diagnostics, mitigation strategies, and redundancy-based fault recovery. Resource sharing capability built in to F6TP provides direct commanding of payload from Government payload control center, bypassing host C&DH. Figure: F6TP/FDK used for a hosted payload interface Wide options for F6TP/FDK command and data paths for hosted payload, will provide flexibility for designers and mission architects: Path 1: Encrypted (tunneled) to bus TT&C Path 2: Encrypted to primary host communication payload(s) via modem (host supplied) Path 3: Encrypted to optionable hosted payload radio (e.g., Inmarsat-based BGAN) 17
