The South Atlantic Anomaly (SAA) is a region of weakened geomagnetic field and in the previous studies, it shows a secular variation with time which is associated with the changing of the magnetic moment. This region also consists of large amounts of energetic charged particles and is danger to space vehicle and astronauts. Thus, it is essential to know the location and movement of the SAA. In this study, three particle monitors onboard Insight-HXMT are used to track the movement and location of the SAA from 2017 June 19 to 2019 June 19. Several particle flux maps are built to show the location of the SAA peak with time. In a grid of map, the particle count is determined by the maximum count rate and the averaged count rate, respectively. We find the results of both methods are consistent very well with each other in deriving the drift rate. The result shows the SAA peak moves westwards with an average drift rate of $0.43\pm {0.01}^o$/yr in longitude and moves northwards with an average drift rate of $0.17\pm {0.01}^o$/yr in latitude, and the drift rate is slightly larger than the result from IGRF 12 (${0.3}^o$/yr) in longitude, but in latitude, the result of IGRF 12 have no obvious change with time.

南大西洋异常（SAA）是地磁场减弱的区域，在先前的研究中，它显示出随时间的长期变化，这与磁矩的变化有关。该区域还包含大量高能带电粒子，对航天器和宇航员具有危险。因此，必须了解SAA的位置和移动。在这项研究中，Insight-HXMT上的三个粒子监测器用于跟踪SAA从2017年6月19日至2019年6月19日的移动和位置。建立了几个粒子通量图，以显示SAA峰随时间的位置。在地图网格中，颗粒数分别由最大计数率和平均计数率确定。我们发现两种方法的结果在推导漂移率方面彼此非常吻合。$0.43\pm {0.01}^{Ø}$/ yr经度，然后向北移动，平均漂移率为 $0.17\pm {0.01}^{Ø}$纬度/ yr，并且漂移率比IGRF 12（${0.3}^{Ø}$/ yr）（经度），但在纬度上，IGRF 12的结果没有随时间变化。
