Abstract: Precise velocity and acceleration is one of the key problems in airborne gravimetry. In this paper, a carrier phase-based velocity and acceleration determination method with precise orbit and clock products is introduced. In static case, the horizontal velocity and acceleration are better than 1.5 mm/s and 2.0 mm/s², respectively, and the vertical ones are about 2.0 mm/s and 2.5 mm/s. In kinematic case, this method is comparable with the multi-reference stations method in precision, and has a higher computational efficiency and success rates. Meanwhile, the sampling rate of precise clock products only influences the velocity, and the order is lower than 1 mm/s. It turns out that the method presented here is effective in airborne gravimetry.
