HIRDLS COMPONENTS
Nine subsystem are integrated together in HIRDLS:
IFC In-Flight Calibration Subsystem
Optical items and electronics to enable radiometric calibration
during flight operations
SSH Sun-Shield Subsystem
Moveable door excludes solar flux from the interior of the instrument
PSS Power Subsystem
Provides basic power conversion and switching
DSS Detector Subsystem
Multi-channel infrared radiometric detector
array and dewar assembly
IPS Instrument processing Subsystem
Signal and data processing to support mission science operations
and housekeeping functions
STH Structural Thermal Subsystem
Primary structural support and enviromental enclosure for
electronic units and telescope
CSS Cooler Subsystem
Provides active cryo-cooling for the instrument detector array
GSS Gyro Subsystem
Provides precision base motion disturbance data
TSS Telescope Subsystem
Instrument telescope and related electronic units
NOTE: subsystems in green are responsability of the US team, subsystems in blue are responsability of the UK team.
