Abstract:
Due to the influence of upper-air wind, the actual ballistic trajectory and range of the artificial precipitation of anti-hail rocket are not inconsistent with the theoretical ballistic values. A tracking system of artificial precipitation enhancement and anti-hail rocket for seeding operation was developed in order to scientifically and precisely enhance the operation and accurately evaluate the effect of the seeding. The system consists of rocket positioning and data transmission. It uses satellite positioning module and the data transmission station mode to transmit the rocket flight trajectory to the ground in real time. Two artificial precipitation enhancement and anti-hail rockets were launched to carry out an artificial precipitation enhancement and anti-hail rocket ballistic tracking experiment. The results showed that all data were received completely except for the initial stage of 4-5 seconds without data when the satellite positioning was out of lock. The actual trajectory of the rocket after wind deviation correction is closer to the theoretical one, and the effect is significant, which is conducive to the 〖JP2〗precise operation of the rocket for precipitation enhancement and hail suppression.
