Completed CG Apparatus

User Guide Compliance Requirement Payload Requirement Status Mass allotment: 6 lbs .4 Over Volume allotment: Top 4.5” Passes The payload’s center of gravity (CG): In 1”X1”X1” envelope of centroid (or in area designated for sharing teams? Developing Method to Test Activation met under requirement: (either 1.SYS.1 or 1.SYS.2) 1.SYS.2 Tested - Passed Structure mounts: Top and bottom bulkheads. No mounts to sides of cans. Passed Sharing: Fully developed? No Response from NW Nazarene

Integration Plan and Procedure Integration Update Payload all but Fully Integrated All but a few components integrated Must have self starting microcontroller May want to amplify CCD and photodiode signals Very close to complete and final integration

Integration Plan and Procedure Procedure Written? Procedure Written in PowerPoint with pictures for each step Example on next slide

Wire CCD Array to Micro Controller. White – Ground Green – VOUT Black – Power Red – ROG Blue - CLK

Integration Plan and Procedure Concerns Broke new shorter fiber optic cable Fix: Use last year’s longer fiber optic cable Note: Fixed No response from Northwestern Nazarene College about integration

Activation Testing Updates Testing Results G-Switch Circuit – Tested: Passed Microcontroller – Just about Must load TERN onto a 32-bit computer to load startup program onto microcontroller Testing Updates Spectrum taken with payload on next slide Full Mission Test Tuesday or Wednesday

Mission Requirements Met Testing Results Mission Requirements Met An optical port is mandatory An adequate, stable and reliable power supply A robust, responsive G-Switch A sensitive, rugged spectrometer operating in the 200 – 1000 nm wavelength range A photodiode sensitive to the same wavelengths as the spectrometer

Mission Requirements Met (cont.) Testing Results Mission Requirements Met (cont.) A microprocessor with two programmable clocks, high speed analog to digital converters, and memory to store the acquired spectra Software program to operate the payload

Mission Requirements Met (cont.) Testing Results Mission Requirements Met (cont.) Mounting hardware for the payload that will withstand the g-forces imposed during testing and flight and will not interfere with the NW Nazarene payload

Mission Requirements not met Testing Results Mission Requirements not met Signal conditioning board to insure the electrical inputs and outputs between the sensors and the microprocessor match in terms of voltage ranges, currents and impedances

Are you ready? We could fly today What is ready? Level of Readiness Are you ready? We could fly today What is ready? Software to fly Hardware What is not ready? Conditioning Circuit

Action items between now and June 15th? Level of Readiness Action items between now and June 15th? Finish conditioning circuit Full Missions Simulation completed this week Make the existing software better Test Possibility of Neutral Density Filter Filter that blocks out wavelengths equally

Are there any remaining questions about check-in? Check-In Inspections Are there any remaining questions about check-in? Have you tried it yet? Check Procedure run? No

Do you have any questions about how this week will go? Final Questions Do you have any questions about how this week will go? Any environmental test day questions? No Any integration day questions? No Any launch day questions? No Food questions? No Have you received your final payment check?
