Abstract
To realize unattended test for launch vehicle, we design and implement the electrical power system rocket-ground wireless interface prototype by means of a short distance high speed wireless communication and high power wireless power supply integration technology that is adapted to test and launch mode. This work gives the overall design and application scheme. The wireless laser power supply and wireless communication integration system consists of high power laser, transmit optical antenna, receive photoelectric conversion array and wireless laser communication equipment (transmit and receive). The transmission and conversion efficiencies of wireless power supply and communication are promoted by optimization design of transmit and receive device, the performance of 2kw power supple at 25m with 500Mbps bidirectional wireless communication capability can be achieved.
