Taiwan’s T.MicroSat-3 and T.MicroSat-4 set for SpaceX Bandwagon-5 launch
Taiwan startup Tron Future Tech is preparing to launch T.MicroSat-3 and T.MicroSat-4, the third and fourth satellites in its “Zhongque” low Earth orbit communications constellation, on SpaceX’s upcoming Bandwagon-5 rideshare mission. German launch integrator Exolaunch, which also supported the first two satellites, will again handle mission integration. Once the two spacecraft reach orbit, the four-satellite constellation will be complete. The project is part of the Taiwan Space Agency’s second-phase startup satellite program, launched in 2023, which assigned three domestic companies to build separate four-CubeSat constellations spanning satellite development, launch, ground control, and application services. Tron Future Tech’s system focuses on broadband communications using four 8U CubeSats. The company said earlier this year that T.MicroSat-1 and T.MicroSat-2 had completed Ka-band downlink verification and entered end-to-end communications testing. With T.MicroSat-3 and T.MicroSat-4, the program will move into its next phase, adding inter-satellite link testing at a designed data rate of 1 Mbps and expanding validation from individual spacecraft to the full constellation. Tron Future Tech has said one target is to build a B5G/6G technology test platform for low Earth orbit constellations.
