The gravity field maps of the satellite gravimetry missions GRACE (Gravity Recovery and Climate Experiment) Follow-On are derived by means precise orbit determination. key observation is biased inter-satellite range, which measured primarily a K-Band Ranging system (KBR) in Follow-On. satellites additionally equipped with Laser Interferometer (LRI), provides measurements lower noise compared to...

Estimating the gravity anomaly causative bodies boundary can facilitate the gravity field interpretation. In this paper, 2D discrete wavelet transform (DWT) is employed as a method to delineate the boundary of the gravity anomaly sources. Hence, the GRACE’ satellite gravity data is decomposed using DWT. DWT decomposites a single approximation coefficients into four distinct components: the appr...

ABSTRACT While giant planet occurrence rates increase with stellar mass, of close-in super-Earths decrease. This is in contradiction to the expectation that total mass planets a system scale protoplanetary disc and hence mass. Since snow line plays an important role formation process, we examine differences temperature structure gas discs around stars different Protoplanetary likely contain dea...

Long-term observation of Earth’s temporal gravity field with enhanced and spatial resolution is a major objective for future satellite missions. Improving the performance accelerometers present in such missions one main paths to explore. In this context, we propose study an original concept hybrid accelerometer associating state-of-the-art electrostatic (EA) promising quantum sensor based on co...
