Ground track density considerations on the resolvability of gravity field harmonics in a repeat orbit
Original language description
The problem of spatial sampling has been studied repeatedly (Wagner et al., 2006; Klokocnik et al., 2008; Weigelt et al., 2009) and simple rules have been derived to limit the maximum order for unconstrained solutions (inversions) for the gravity field parameters or their variations from observations of a single satellite. Here we work with the latest rule from Weigelt et al. (2013) which distinguishes the maximum attainable order according to the parity of the two parameters defining the repeat orbit or orbital resonance, beta the number of nodal satellite's revolutions in alpha nodal days (alpha, beta co-prime integers, the ratio beta/alpha irreducible).
