摘要
介绍了FG5x在FG5绝对重力仪基础上的改进,以及FG5x-246与FG5绝对重力仪比对测量实验的情况,并分析了测量结果。研究结果显示,FG5x-246与FG5绝对重力仪的观测结果没有明显差异,二者一致性较好;FG5x-246抗干扰能力较强,观测重复性较好,离散度优于±1×10-8 ms-2,其测量性能较FG5有所提升。
This paper introduced the improvements of FG5 x absolute gravimeter and the contrast test of FG5x-246 absolute gravimeter with FG5 at first. And then, the paper analyzed the measuring results of the two kinds of absolute gravimeters. The results indicate that there is little difference between FG5x-246 and FG5, the difference of accuracy is within ±2×10- 8ms-2. FG5x-246's scatter is less than ±1×10-8ms-2, with stronger anti-interference ability. FG5x-246's measurement ability is better than FG5.
