Advanced Challenge 1

This challenge targets official GRACE data processing centers and groups that already have their own softwares to process GRACE like data products. The simulation is sensor based, which means we provide GRACE like sensor data, and the format of the simulated data are like GRACE data products. The goal of simulation is to test different gravity field recovery approaches in a closed loop simulation.

Simulation Strategy

The simulation scenario is similar to the basic challenge 1, with added accelerometer and star camera data. The gravity field model and its maximum degree used in the integration as well as the noise models used to corrupt the data remain hidden. The figure below illustrated the simulation scenario.

 

 

Note

We've found a bug in the data and will update the data as soon as possible.
