| 摘 要： | 针对不断提高的炮兵装备射程，定量分析采用空间大地坐标系和高斯平面直角坐标系计算炮目距离和方向时的差别，同时分析采用1954北京坐标系统和2000中国大地坐标系统对距离计算精度的影响。分析结果表明：由于投影变形，在高斯平面直角坐标系下计算炮目距离时误差可达1‰，计算炮目方向的误差在距离远时也较大，应视情况予以修正；采用1954北京坐标系统和2000中国大地坐标系统计算炮目距离时，二者计算结果之差小于实际距离的0.05‰，其影响可忽略。

| Abstract: | The differences among the gun-target distances and directions calculated using the space geodetic coordinate system and the Gauss plane rectangular coordinate system are quantitatively analyzed, and the influences of BJS54 and CGCS2000 on distance calculation accuracy are also analyzed. The results show that, due to projection distortion, the gun-target distance error calculated using the Gauss plane rectangular coordinate system is up to 1‰, and the gun-target direction error is larger at a farther gun-target distance. When BJS54 and CGCS2000 are used to calculate the gun-target distance, the difference between the calculated results is less than the actual distance of 0.05‰, which can be ignored. |
