        "Description": "This set of housekeeping data from the IMAGE mission comes from the Central Interface Data Processor (CIDP) and the interface with the Spacecraft/System Control Unit (SCU).   The CIDP provides the following major functions for the Observatory:\n(1) Instrument data acquisition, processing, and compression.\n(2) Stored command processing.\n(3) Command receipt (from the SCU), processing, storage (if a delayed command),\nand transfer to the instruments.\n(4) Time/attitude synchronization with the spacecraftÕs Attitude Determination\nand Control system for generation of the nadir and sun pulse signals sent to\nthe instruments.\n(5) Deckplate thermal control.\n(6) Additional EEPROM storage for instrument software or tables.\n(7) Power switching and current limiting.\n\nThe SCU provides the following major functions for the Observatory: \n(1) Ground command receipt, processing, storage (for delayed command execution)\nand relay to the CIDP.\n(2) Telemetry data formatting and downlink\n(3) Spacecraft attitude determination and control.\n(4) Spacecraft thermal control.\n(5) Spacecraft power management.\n(6) Spacecraft housekeeping data acquisition, formatting, and storage.\n(7) Management of the Mass Memory Module.\n(8) Management of the engineering and high speed telemetry downlink.\n(9) Safe/hold management of the Observatory.\n\nProducts include:\n  \nIM_HK_ADS: Image Attitude Determination System Housekeeping\nIM_HK_AST: Image Autonomous Star Tracker Housekeeping \nIM_HK_COM: Image Communication Systems Housekeeping \nIM_HK_FSW: Image Flight Software Housekeeping \nIM_HK_PWR: Image Power Systems Housekeeping\nIM_HK_TML: Image Thermal Housekeeping \n              ",
