STF-1 is a company that specializes in simulation technologies for small satellites. The company's primary focus is on demonstrating the utility of the NASA Operational Simulator for Small Satellites (NOS3) technologies across the small satellite development cycle. NOS3 is a suite of tools developed by NASA IV&V that provides a software development environment, multi-target build system, operator interface/ground station, dynamics and environment simulations, and software-based hardware models. The company also offers simulation-based test environments, including a SmallSat simulation-based test environment, which integrates ITC simulation technologies. Additionally, STF-1 provides services such as science experiments, including space weather, performance and durability of III-V Nitride-based materials, and navigation. With its expertise in simulation technologies, STF-1 helps small satellite developers overcome size, weight, and power (SWaP) constraints.
