ECOSTRESS Spacecraft Attitude and Position Data

Global data between 52 degrees N and S latitudes provides corrected and uncorrected attitude quaternions and spacecraft ephemeris for the ECOSTRESS instrument on the International Space Station. The Level 1B product supplies Earth-centered inertial position and velocity vectors at 1-second intervals, copied from ISS raw data. This Version 1 dataset from NASA's LPCLOUD was decommissioned in April 2025, with users directed to the newer ECO_L1B_ATT Version 2 product.

Use Cases

• Correcting geolocation of ECOSTRESS land surface temperature observations using the attitude quaternion and ephemeris data.
• Analyzing spacecraft orientation and orbital mechanics for the International Space Station using the provided quaternion and Earth-centered inertial position/velocity vectors.
• Supporting the geometric processing pipeline for higher-level ECOSTRESS data products by providing foundational pointing and position information.

Strengths

• Provides high-temporal-resolution data with vectors recorded at 1-second intervals.
• Contains both corrected and uncorrected data versions, allowing for analysis of processing adjustments.
• Data collection covers a global latitudinal range from 52°N to 52°S.

Limitations

• The dataset is decommissioned as of April 22, 2025, indicating it is legacy and users are directed to a newer version.
• Contains known data acquisition gaps due to instrument anomalies in 2018 and 2019, affecting temporal continuity.
• Cannot be searched by geographic location as it lacks spatial attributes, requiring search by orbit number.
