TABLE 3

Average RMS of the Relative Orbital Errors Between GRACE C and D for December 1–7, 2019 σ_OURE,rv denotes the RMS of the relative OURE not considering the relative clock errors (see Equation (9)), and σ_SISRE,rv denotes the relative SISRE considering the relative clock errors (see Equation (10)).
