6 FAQs about [Research on spatial prediction of gravity solar container field]

How can gravity field models preserve original signals while minimizing random errors?

In order to achieve gravity field models that preserve the original signals while minimizing random errors, we combine various TVGFMs using different weighting schemes. To assess whether the combination results meet our expectations, it is essential to conduct validations to evaluate the performance of the individual and combined models.

Why does the DNN gravity field model have poor prediction results?

Due to the limited spatial distribution of the training dataset, the trained DNN gravity field model has poor prediction results of the gravity field outside the probe's flight orbit, such as the area near the landing trajectory of the probe's descent stage.

Why is time-variable Earth's gravity field important?

Accurate time-variable Earth’s gravity field information is important for precise orbit determination (POD) of low Earth orbiters (LEO). In particular the POD of altimeter satellites benefits from accurate modelling of the time-variable gravity field.

How important is a time-variable gravity field model?

Moreover, the precise GRACE/GRACE-FO time-variable gravity field model (TVGFM) is invaluable for enhancing the orbit determination of low-orbit satellites, underscoring the importance of refining existing TVGFMs 17.

Which gravity field model should be used to determine pod of LEO satellites?

Consequently, POD of LEO satellites requires a gravity field model with a higher spherical harmonic resolution than POD of satellites orbiting the Earth at higher altitudes. Global gravity field models are commonly determined from the analysis of satellite orbits.

What is cost-G – time-variable gravity field?

In particular the POD of altimeter satellites benefits from accurate modelling of the time-variable gravity field. The Combination Service for Time-variable Gravity Fields (COST-G) provides monthly gravity fields based on a combination of GRACE/GRACE-FO derived monthly gravity field solutions from different analysis centers.
