Wireless Power Transmission (WPT) technology using a satellite-to-satellite system represents a valuable and convenient technology for transferring power wirelessly among Space Solar Power Satellites (SSPS) to Satellite and potential upcoming interplanetary missions. This direct transmission offers a possible solution to deliver continuous, convenient, and unlimited energy supply to satellites help replace traditional power storage and reduce the weight and ultimately the costs of launching satellites. Satellite industries traditionally use photovoltaic cells and nuclear generators to satisfy the needed electricity needed by spacecraft. Current power generation and effective management systems occupy up to 10-25% of the satellite's mass. The concept of laser-based WPT from Energy Satellite (E-Sat) can overcome substantial problems. The current design of SSPS primarily focuses on designing a massive satellite to generate and transmit gigawatts of energy to an Earth-based ground receiving antenna. This consistent idea can be adopted for spacecraft by developing a constellation of E-Sat called Energy Orbit (E-Orbit) to supply sufficient power to spacecraft within range. It will increase the impressive performance and operational lifetime, especially for small and cube satellites using microwaves and laser-based power transmission. By developing a small scale SSPS,E-Sat for WPT application in space, followed by a practical demonstration of mother-daughter satellite and accurately evaluating the possibility for subsequent implementation. In addition, Creating 1600 E-Sats constellations to fulfill the power demand in low earth orbit. Nevertheless, another potential avenue where E-Orbit supports a possible application is its utility towards rovers and habitat. For instance, the rovers find it difficult to investigate in the far side, crater, and polar region of the Moon, where sunlight is unavailable for a few days. This challenge can be suitably overcome by employing an E-Sats, which can be used for WPT, independent of its location. Such techniques demonstrate possible applications towards power transmission for unmanned aerial vehicles for faster mapping purposes. As such, the dependence of those aerial vehicles towards fixed energy storage becomes alleviated. Simultaneously the future habitat on Mars and the Moon will receive continuous power by developing a perfect Mars and Moon E-Orbit system for interplanetary and solar-system investigation mission satellites to achieve continuous power. The theoretical modeling allows the analysis of power conversion or transmission for each unit in terms of laser impacts, transmission efficiency, and photovoltaic-cell thermal property. Maximum power transmission efficiency is calculated based on a linear approximation of power conversation between electricity-to-laser and laser-to-electricity validated by numerical simulation. This efficiency variation depends on the selection of Laser, transmitter, transmission distance, and photovoltaic cells, the same as increasing the maximum transmission efficiency of information in a wireless communication network. Consequently, this thesis gives insight into wireless power transmission in general and adequate guidelines of the satellite to satellite power transmission system design in practice. The development and demonstration of this technology can help fulfill Space Solar Power Satellites' idea to transfer gigawatts of renewable energy to Earth.
