GOME-2 control and data handling system
GOME-2 block diagram and electrical interfaces
The Control and Data Handling System is built by the Control and Data Handling Unit (CDHU) and the GOME Power Distribution Unit (GPDU). All electrical and operational interfaces to GOME-2 are routed through the Control and Data Handling Unit (CDHU).
Within this unit, a primary processor is responsible for all Instrument Control Unit (ICU) functions such as the:
- reception and expansion of macro commands
- maintenance of history file
- monitoring of instrument parameters
- preparation of housekeeping telemetry formats
The ICU controls the operation of the Scan Unit via a bi-directional serial interface and provides each of the four FPA thermoelectric coolers with an individual thermal-control loop. A secondary processor controlling the Science Data Management board takes care of:
- science data collection
- processing
- packetisation of data (where the layout of data in these packets has been predefined)
