PM1ATTNR: Aqua Spacecraft Attitude Data for Geolocation

NASA's Aqua satellite provides near real-time spacecraft attitude data, a MODIS ancillary product. This data is preprocessed by the ECS SDP Toolkit and is used for determining the geolocation of Earth remote sensing observations. Files are generated daily in a native binary format with a specific naming convention indicating acquisition time and version.

Use Cases

• Correcting geolocation of MODIS imagery based on spacecraft orientation parameters.
• Calibrating and validating satellite observation positioning in near real-time processing chains.
• Analyzing platform stability and orbital characteristics for the Aqua satellite mission.

Strengths

• Data is produced by NASA, a leading space agency, ensuring authoritative sourcing.
• Available in near real-time (NRT), supporting time-sensitive applications.
• Preprocessed to an internal standard supported by the ECS SDP Toolkit, indicating a level of quality control.

Limitations

• Critical metadata is missing: column names, row counts, and file sizes are unknown across all sources.
• The license is ambiguously listed as 'other-license-specified' without details.
• Data freshness is unclear; the 'last updated' date of 2026-04-09 appears to be a future placeholder or system artifact.
