MISSION CONTEXT
ICESat-2 carries the ATLAS photon-counting laser altimeter. ATL02 is the Level-1B converted telemetry product used here to examine heterogeneous orbital engineering telemetry and observation quality.
- LOCATION
- Earth orbit · near-polar global coverage · target: Earth
- RELATION TO SAMPLE
- Mission illustration. The audited ATL02 sample is engineering telemetry, not an image product.

INTERPRETATION BOUNDARY
How the dataset may be used scientifically
Current orbital telemetry and quality context; no curated spacecraft-fault intervals. Unusual intervals cannot be labelled faults without authoritative evidence.
NATRO treats accessibility, integrity, schema recovery, cohort construction and experimental evidence as separate scientific states. A recovered field is evidence of data structure; it is not evidence of a spacecraft fault or a model result.
ROLE IN NATRO
Reliability-aware spacecraft health inference under degraded multivariate telemetry
The study separates physical-system state from observation quality. Each dataset contributes a different form of evidence: controlled faults, labelled historical anomalies, current operational telemetry, extreme-environment multisensor observations, or independent ESA validation.
