The method and precision of trajectory identification of a range correction fuze based on projectile of compound extended range by base bleed and rocket were studied.

This paper analyzes the internal and external study status of one dimension trajectory correction fuzes, takes apart the advantages and disadvantages of three kinds of model dampers adapted to them; and collates the main parameters of these dampers.

The range correction ability of impulse force and body attitude while impulse forces not acting on the center of gravity was studied.

The effect of range correction system of long-range rocket adopting SINS is analyzed through numerical simulation.

A range correction for the attitude stabilized rocket is necessary.

Based on the calculational method, this paper also discusses calculational method for maximum corrected range.

By analyzing the characteristic of one-dimensional trajectory correction fuze based on GPS and the data characteristic of GPS receiver,the paper puts forward the real time trajectory modified method,and states the emulation experiments.

This paper analyses the whole task of recognization software according of trajectory correction fuze(TCF),and designs the sub -programs of these program modules.

Predicting trajectory point of fall based on GPS measures part of trajectory is one key technology of trajectory correction fuze adopted GPS.
