Required precision in tidal acceleration measurements for the nine selected bodies assuming a mission duration of 10 times the tidal periods specific for each body, except Mars whereby the mission duration is equal to one Martian year. The dashed red and black lines are, respectively, the compact and high-performance foreseen precision of the instruments, i.e. the instrument self-noise. The labels show the aimed tidal gravimeter factor accuracies for the instrument’s measurements. The values are equal to \(\kappa [\delta _{\max}-\delta _{\min}]\) with \(\kappa =0.1\)
