About FlexSat®

TMC Technologies’ FlexSat® platform delivers a fully integrated, modular FlatSat solution that brings realistic hardware-in-the-loop testing to your satellite mission. By combining flight-grade electronics, software, and mechanical interfaces into one non-proprietary package, FlexSat® lets you prototype, validate, and iterate faster, whether you’re in the lab, the classroom, or the clean room. FlexSat® also complements TMC’s role as lead developer of the NASA Open Source Simulator for SmallSats (NOS3). Together, hardware and software give you end-to-end mission-level fidelity.
