The solar cells produce electrical power (current) from incident sunlight. However, individual solar cells generate very little power. So, in order to generate more power, a group of cells that are present in an array form can be used. Solar…
Ocean shipping continues to be the primary transportation method of billions of dollars in goods. As such a massive industry, safety is incredibly important. Underwater inspection of shipping vessels is important for many reasons. It saves money and time by…
Virtually every modern naval weapons system, in fulfilling its mission, is highly dependent upon the performance characteristics of its electrochemical power supply. For example, batteries are used to power detection, guidance, control, ignition, propulsion, arming, fuzing, transmitting and jamming devices.…
Satellite present in an orbit should be operated continuously during its life span. All the satellites require internal power in order to operate various electronic systems and communications payloads that are present in it. The Electrical Power System (EPS) is…
In the history of spaceflight, almost all spacecraft have been manufactured and assembled on the ground, then integrated into a launch vehicle for delivery into orbit. This approach imposes significant limitations on the size, volume, and design of payloads that…
