Aim at the problem that there is no GJB and other relevant standards for the trial and assessment of 1D trajectory correction projectiles in China, the trial and assessment methods of 1D trajectory correction projectiles are analyzed in combination with the development experience of two domestic models 1D ballistic correction projectiles and with reference to the conventional ammunition trial and assessment methods. The results show that the analysis provides a reference for the trial and assessment of 1D and 2D trajectory correction projectiles in the future, and is helpful to the compilation and improvement of the trial regulations of trajectory correction projectiles.
