GB/T 44381-2024 in English

This standard systematically regulates the quality control system of the entire life cycle of lunar and planetary exploration data for the first time, and innovatively integrates scientific payload data such as CCD stereo cameras and laser altimeters with the PDS4 standard. By establishing six major inspection elements, four-level defect classification and a five-level evaluation system, a quantifiable assessment of data quality is achieved.

Integrity verification requires that metadata contain 9 mandatory fields, among which the topographic camera data must verify the following:

• The logical correlation between the detection cycle number and the orbit number
• The coordinate system consistency of the geometric positioning grid file

For special payload data such as lunar radar, it is recommended to:

1. Establish an instrument-specific verification rule library
2. Develop an automated verification plug-in and integrate it into the PDS label generation process
3. Add a manual review link for data above level 2B
