The Department of Defense (DoD) is seeking proposals for the topic of "Digital Flatsat" in their SBIR 23.3 BAA solicitation. The Air Force branch is specifically interested in this topic. The objective is to develop a fully functioning Flatsat through a cloud-resident Digital Twin model that allows full mission emulation of SDA mission features and enables testing of new bus, payload, network, and mission commands before uploading them to vehicles in orbit. The emphasis is on minimizing hardware and prioritizing massless payload deployment. The resulting flatsats should fulfill the same mission requirements as traditional hardware/software flatsats but would exist as cloud-based software solutions.
The project will be conducted in three phases. In Phase I, feasibility will be demonstrated through a computer model and simulation tool that shows the basic interfaces for a digital FlatSat supporting future system development. In Phase II, applicants will be expected to provide a fully operable digital FlatSat that allows users to create and provide a simulation model interfacing with existing SDA FlatSat hardware and emulating it for replication online.
Phase III will focus on dual-use applications, where the Space Development Agency (SDA) aims to provide spiral development of smallsats for continuous improvement and the addition of new technology. A Digital FlatSat would support the development and integration of new systems through a digital twin model, eliminating the need for building and integrating hardware. This approach allows for more options to be evaluated and compared. A successful Phase III would evaluate design trades for future SDA tranches, reduce engineering design time, and increase the deployment of novel and innovative technology to stay ahead of near-peer competitors in space system design.
