Analysis of attitude noise for ITSG GRACE-FO processing
The GRACE/GRACE-FO mission has monitored monthly variations of Earth's gravity field for more than two decades. One source of error is attitude errors, that propagate to inter-satellite range observations through the antenna centre offset correction. This error is proportional to the nominal angle deviation. For GRACE-FO, the third additional camera on-Gabriel Valles Valverde +1 more

Towards understanding the measurements of the GRACE FO electrostatic accelerometers
Some of the most prominent anomalies and open questions concerning the measurements of the ultrasensitive accelerometers on both GRACE FO spacecraft are related to the activation of attitude thrusters. As a consequence, measurements around thruster activations are replaced by modeled data for the GFO1 accelerometer, while the complete measurements are ...Jakob Flury, Igor Koch, Mathias Frye

Variations in Earth’s rotation, encompassing polar motion (PM) and the length-of-day (LOD) changes, result from a variety of factors influencing mass distribution and movement. These factors include the redistribution of air and water masses within the climate system and the solid Earth, and exchanges of angular momentum between the core and ...
