Abstract: The PanelSat Launch System consists of PanelSat(s) and it's/their Launcher. It serves to launch one, better several satellites into space, whereby besides unfurling of the thin film solar cell panels off their rolls no further deployment is needed. PanelSats are small agile spacecraft thought especially for observation and communication services in LEO, which are using their thin film solar cell panels for both, harvesting electric energy as well as for fuel less station keeping, steering, pointing and propulsion. In contrast to conventional satellites with their 3-axis control design, PanelSats are not locked to only 3 axles and can tilt and point into several directions (depending on the number of panels). Besides Roller Reefing for fuel less attitude control PanelSats feature “Soso Steering” (switch on, switch off) which adds even better fuel less agility compared to prior art satellites.
