ROSETTA-ORBITER GIADA: Commissioning Phase 2 Instrument Data

September-October 2004 data from the GIADA instrument's second commissioning phase aboard the Rosetta orbiter. The dataset contains housekeeping, calibration, and scientific data converted from ADC counts to engineering values, provided by NASA. Data from the Grain Detection System and Impact Sensor are due to noise, as no dust events were expected during this phase.

Use Cases

• Evaluating instrument health and behavior based on housekeeping and calibration data mentioned in the description.
• Analyzing frequency changes in the Micro-Balance System for potential contaminant deposition as described.
• Comparing noise characteristics in scientific data channels during a known quiet mission phase.
• Benchmarking instrument performance against data from other mission phases as suggested in the description.

Strengths

• Data quality for housekeeping and calibration is explicitly stated as 'good'.
• Data have been converted from raw ADC counts to engineering values.
• Specific in-flight test scenarios are documented with dates (e.g., 'Interference 1' on 20-22 September 2004).

Limitations

• Scientific data are described as 'due to noise' and 'not real scientific data'.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
