Abstract 

Satellite attitude determination is critical for accurately measuring and controlling a satellite’s orientation in orbit using a variety of sensors and methods. Currently, low-low Satellite-to-Satellite Tracking (ll-SST) missions—such as GRACE(-FO)—and upcoming missions like Magic primarily rely on quaternion data from onboard star camera sensors. To enhance attitude determination, we propose a GSCF fusion method. Taking GRACE-FO as an example, our dataset includes both the GSCF-fused attitude data and the traditionally fused (Trad) attitude data stored in .txt files, as well as GNSS-orbit-derived attitude data in .npy files, covering the period from January 1, 2020, to December 31, 2020.

Instructions: 

The attitude products are derived by the GSCF approach and traditional fusion approach from February 1, 2020, to December 31, 2020, respectively. Additionally, it provides GNSS-orbit-only attitude data from February 1, 2020, to December 31, 2020.
