Mission Objective:Mission Objective:Daniel Taylor, Danny Kendrick, Christian McFaddenMission Objective:Mission Objective:Our Our goal is to design and build a simulator goal is to design and build a simulator that can reproduce the sun as a source of radiation, that can reproduce the sun as a source of radiation, and rotate the cube satellite in order to determine the and rotate the cube satellite in order to determine the amount of power it receives from the solar cells with amount of power it receives from the solar cells with respect to its angle.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 sunspectrum and intensity as the sun A reflective surface to represent the albedoof 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 cubeIG32P 24VDC 008 RPM Gear MotorReduction RatioRated TorqueRated SpeedRated CurrentNo Load SpeedNo Load Currentkgf-cm rpm mA rpm mA1:721 12 8 <900mA 8 <450mAWe will use stepper motors to control the angle at which the swing rotatesUCD1/7; UCD2/8Dimensions (mm): 28 x 24Step angle (°): 7.5Holding torque * (cNm): 1.6 – 2.7ControllerVisual Feedback+Halogen+metalhalide Halogen BulbMercury Arc BulbHalogen+metalhalide Halogen BulbEnvironmental SimulatorComputer InterfaceRadiation SourcesRotation StructureInterfaceControllersVisual OutputSourcesSolar SourceAlbedo/Earth ReflectionSecuring DeviceMotorFrameMaterialsOrientation Secure the Cubesat into clamp Orientate system to a certain degree Set DC motor to desired rpm Turn on light source Turn on light source Analyze results using computer
