Daniel Taylor Danny Kendrick Christian McFadden Mission Objective Our goal is to design and build a simulator that can reproduce the sun as a source of radiation and rotate the cube satellite in order to determine the amount of power it receives from the solar cells with respect to its angle Rotate satellite about multiple axes at a speed of 1 5 rpm Produce a light source with the same spectrum and intensity as the sun A reflective surface to represent the albedo of the earth 30 No spurious light reflections Ideally fit into an anechoic chamber We ll be using a DC motor to power the rotation of the cube IG32P 24VDC 008 RPM Gear Motor Reductio n Ratio 1 721 Rated Torque kgf cm 12 Rated Speed rpm 8 Rated No Load No Load Current Speed Current mA rpm mA 900mA 8 450mA We will use stepper motors to control the angle at which the swing rotates UCD1 7 UCD2 8 Dimensions mm 28 x 24 Step angle 7 5 Holding torque cNm 1 6 2 7 Controller Visual Feedback Mercury Arc Bulb Halogen Bulb Halogen metal halide Environmental Simulator Computer Interface Radiation Sources Rotation Structure Controllers Solar Source Securing Device Frame Visual Output Albedo Earth Reflection Motor Materials Orientation Secure the Cubesat into clamp Orientate system to a certain degree Set DC motor to desired rpm Turn on light source Analyze results using computer interface
