1. ROCSAT-2 Current Status of ISUAL Project Yeou-Shin Chang of NSPO Jyh-Long Chern of NCKU Henry Heetderks of UCB October 3, 2001

2. ROCSAT-2 Current Status  Design of the ISUAL âMechanical and optical design of SP is complete with released drawings on ftp server âMechanical design of AEP is nearly complete åFrames for Low Voltage Power Supply and Power Control Board are in fabrication in machine shop âAEP Power System design is complete åPCB layouts for both LVPS and Power Controller are complete åETU board etch is complete for both boards åParts loading of both boards is in process âAEP DPU breadboard is under test with SOH and Command circuitry checked out. Science data interface installed and under test with GSE.  IGSE Computers are set up with Hardware interfaces installed âDesign of SOH and Command interface is complete âActel development system is set up âDesign and construction of Science Data interface is complete åCircuit board under test åActel has been burned and is under test

3. ROCSAT-2 Current Status (con’t)  ISD Development Status âExisting DPU breadboard with add-on memory circuit will be used as the ISD âDevelopment of memory circuit will not affect DPU development âUCB on track to support a June, 2001 ISD delivery  Science Data Distribution Center âIncorporating the CCSDS standard in data format âStudying the telemetry commands for the ISUAL operation âReviewing CDF Skeleton Table for ISUAL data âEvaluating data query functions and schemes for the ISUAL data

4. ROCSAT-2 Issues and Concerns  Thermal Control Design-  Survival Heater Lines incorporated into instrument design  TM and TC ICD  Harness Routing
