Raspberry PI Based OFFLINE MEDIA SERVER
In this research paper, an economically low computing environment using Raspberry Pi zero W model based systems is very Well organized to use computing system in the developing environment. All this work will be done on Linux OS platform and it will help to develop the server using the Raspberry pi. A partition will be made on the SD card which is connected to the Raspberry pi that helps to store the media and work with them Offline. This accommodate up to 50 users to work offline.
A conceptual design study titled Deep-space Optical Terminals was recently completed for an optical communication ::: technology demonstration from Mars in the 2018 time frame. We report on engineering trades for the entire system, ::: and for individual subsystems including the flight terminal, the ground receiver and the ground transmitter. A point ::: design is described to meet the requirement for greater than 0.25 Gb/s downlink from the nearest distance to Mars of ::: 0.42 AU with a maximum mass and power allocation of 40 kg and 110 W. Furthermore, the concept design addresses ::: link closure at the farthest Mars range of 2.7 AU. Maximum uplink data-rate of 0.3 Mb/s and ranging with 30 cm ::: precision are also addressed.
