Gravitoinertial acceleration (GIA) tilt angle values listed are for translations along Earth-horizontal axes (polar angle φ = 90°); translations along other directions at the same frequency and peak translational acceleration along non-Earth-horizontal axes with 0 ≤ φ ≤ 90° are smaller that equal to tan−1[Asin(φ)/(g + Acos(φ)], where A is peak translational acceleration in m/s2 and g = 9.8 m/s2.
