The invention relates to a ballistic shock wave-based time difference of arrival positioning device, in particular to a ballistic shock wave-based projectile drop point positioning device, system and method, which are used for solving the problems of the existing projectile drop point positioning device that the displacement compensation method of a measuring device is complicated, the precision of an adopted time synchronization mode is not high, and the positioning accuracy is low. In order to overcome the defects of relatively complicated structure, relatively complicated structure of a measuring point array, relatively difficult transportation, arrangement, maintenance and guarantee and unsuitability for rapid deployment, the projectile falling point positioning device based on the ballistic shock wave comprises a signal processing module, a sensor module, a differential Beidou/GPS module, a low-power-consumption communication module, a power management module and a direction and tilt angle sensor module.
