This activity will study the effective complexity, resource requirements and overall system-level efficiency of utilizing a High Intensity Laser Power Beaming System (HILPBS) for powering a rover operating in the proximity (<15km) of a lander. The HILPBS would consist of: · a high power laser (and possibly a small telescope) feeding the optical beam to a a high-rise gimbal on the lander. The laser would be powered by solar panels (~3 kW) or nuclear power source and batteries. · a receiver panel (~ 1600 cm2) made of gallium or VMJ photovoltaic cells mounted high on the rover.The HILPB would deliver sufficient watts of power to recharge the relatively small batteries on the rover every time the rover is stationary and has line-of-sight visibility of the lander. This study shall allow to derive sizing formulas for different power cases for the receiver as well as the transmitting side, in order to elaborate on the advantages/disadvantages of a HILPBS solution with respect to a more conventional PV/battery solution.
