The power system 606 provides electrical power for the operation of the components onboard the satellite 502. The power system 606 may include components to generate electrical energy. For example, the power system 606 may comprise one or more photovoltaic arrays 630 comprising a plurality of photovoltaic cells, thermoelectric devices, fuel cells, and so forth. One or more PV array actuators 632 may be used to change the orientation of the photovoltaic array(s) 630 relative to the satellite 502. For example, the PV array actuator 632 may comprise a motor. The power system 606 may include components to store electrical energy. For example, the power system 606 may comprise one or more batteries 634, fuel cells, and so forth.

The maneuvering system 608 maintains the satellite 502 in one or more of a specified orientation or orbit 504. For example, the maneuvering system 608 may stabilize satellite 502 with respect to one or more axes. In another example, the maneuvering system 808 may move the satellite 502 to a specified orbit 504. The maneuvering system 608 may include one or more of reaction wheel(s) 640, thrusters 642, magnetic torque rods 644, solar sails, drag devices, and so forth. The thrusters 642 may include, but are not limited to, cold gas thrusters, hypergolic thrusters, solid-fuel thrusters, ion thrusters, arcj et thrusters, electrothermal thrusters, and so forth. During operation, the thrusters may expend propellant. For example, an electrothermal thruster may use water as a propellant, using electrical power obtained from the power system 606 to expel the water and produce thrust. During operation, the maneuvering system 608 may use data obtained from one or more of the sensors 610.
