Abstract: The PanelSat 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.

Abstract: A solar sail spacecraft is designed to steer and move in space by using solar radiation pressure as a driving force, therefore allowing fuelless propulsion, station keeping and attitude control. A solar power satellite utilizes thrusters only to stay in an rather stationary orbit. Its purpose is, to collect energy and transfer it to a given location, usually to Earth. The intention of the present invention is to create a hybrid of a solar sail spacecraft and a power satellite for space based power generation and transmission, which is mobile and provides both, fuelless solar sailing and electric thrusters as means of propulsion. The mobile Solar Sail Power Station serves as solar energy collector and can be connected by docking with other power stations and with a transmitter unit for energy transmission, whereby the transmitter features its own fuelless pointing and attitude control devices.

Abstract: Fuel less ACS for solar sails, using furl- and unfurl able ballast-sail-foil-segments for simultaneously displacement of center of mass and center of solar radiation pressure into opposite directions to each other. Solar-Sail-Launch-System for direct launch of the System-Sail including already docked in daughter units and payload in the sailcraft's central docking station. Unlike todays launch able solar sail designs the System-Sail features ample solar cell arrays and additional SEP-thruster-units for steering and propulsion, while the solar sail rather serves for longtime fuel less attitude controls and station keeping. The SEP-Sailcraft may also serve as a carrier-ship for daughter-units in asteroid exploration missions and is able to deliver prospector landers back to LEO with furled in foils.
