Abstract :
The application of wireless power transmission to satellite systems offers several advantages for payloads requiring a pristine space environment. By removing the sources of acceleration associated with onboard power systems such as solar tracking photovoltaic arrays, eliminating station keeping and reducing thermal shock from eclipse, a more benign microgravity environment can be achieved. Active control systems, such as magnetic suspension, which have been developed to reduce the vibration acceleration to sensitive payloads may not be adequate in all applications. The use of wireless power transmission permits the energy receiving satellite to float freely in space while the energy generating satellite supplies power and maintains its relative position. The elements of a wireless power transmission system are detailed and contrasted with conventional onboard satellite power systems. Three technologies are considered for the transmission system: high efficiency lamps, lasers and microwave systems
