Ground track density considerations on the resolvability of gravity field harmonics in a repeat
Original language description
One of the limiting factors in the determination of global gravity field parameters is the spatial sampling, namely during phases when the satellite is in an orbit with few revolutions for each repeat cycle. This often happens when it is freely passing (drifting) through the atmosphere and encountering a fair number of such deficient repeat orbits. This research was triggered in 2004 by the significant but only temporary, 2-3 months long, decrease of the accuracy of monthly solutions for the gravity field variations derived from GRACE. The reason for the dip was the 61/4 resonance in the GRACE orbits in autumn 2004. At this resonance, the ground track density dramatically decreased and large (mainly longitude) gaps appeared in the data-coverage of theglobe. The problem of spatial sampling has been studied repeatedly and simple rules have been derived to limit the maximum order for unconstrained solutions (inversions) for the gravity field parameters or their variations from observatio
