The system architecture is built around the following components:
- A space segment, the MicroCarb satellite, comprising:
- A Myriade spacecraft bus
- A passive spectrometer instrument
- A control ground segment based on elements shared with other missions:
- A command - control centre (CCC) common to Myriade and Proteus family missions
- Communications in S-band and X-band using the CNES multi-mission 2-GHz and 8-GHz ground station network and a data communication network
- Additional CNES multi-mission support facilities: main control room, operational orbit facility, space debris management facility, etc.
- A digital satellite simulator used to conduct tests and qualify the system,
- A ground segment dedicated to the payload (PLGS), comprising:
- A data acquisition, archiving and distribution centre (PLDS)
- A mission planning and payload operational centre, responsible for instrument monitoring and control (PLOC)
- A scientific data processing and management centre (PLDP)
- Expertise centres (TEC) in charge of monitoring product quality
- A launch service comprising:
- Carriage of the MicroCarb satellite aboard a launcher
- Launch support facilities and services
Data processing also requires some exogenous data such as meteorological data provided by the European Centre for Medium-Range Weather Forecasts (ECMWF).
Products will be exploited and made available to the international scientific community through the AERIS data centre.
Calibration operations performed during the commissioning phase, then routinely, use the data provided by the TCCON network of atmospheric ground stations.
