Formal uncertainties (σ) of gravity field coefficients derived from combined 2W and SST mode for mission durations of 6-month, 1-year, 1.5-year, and 2-year periods. Longer durations lead to modest reductions in uncertainties, with diminishing returns beyond the first year. Across all cases, uncertainty patterns remain consistent across degrees.
