Abstract
Satellites are objects that revolve around other objects in certain period of revolution and rotation. There are two types of satellites, natural and artificial satellites. There are several types of artificial satellites based on their use such as weather satellites, military satellites, science education satellites, and communications satellites. Artificial satellites can follow a position according to the movement of the earth, which is called the geostationary orbital position. When a satellite is in a geostationary orbit position, its speed will be relatively low, allowing the position satellite to be moved. The surveillance area has been regulated in ITU-R Rec. S. 484. about the control area tolerance limit of less ±0,5° for operational fixed satellite. In this case, the mobile satellite requires a lot of power and shortens the life of the satellite. Predicting the orbital displacement time interval involves two orbital methods, namely Cowell method and Encke method. Both of these methods can be used to determine the length of time that occurs when the satellite is moved. This study aims to compare which method can determine time intervals more accurately. The advantage of this research is that there are two methods that can be used to determine the time interval of the satellite orbitals. Quantitative comparative research method for field survey through comparison of applied research in main control satellites. The results of the comparison of the two methods will be used for orbital purposes, combined with positional and mathematical factors to determine the duration of orbital shift.
卫星是在一定的公转和旋转周期内围绕其他物体旋转的物体。有两种类型的卫星,自然卫星和人造卫星。人造卫星根据其用途有几种类型,如气象卫星、军事卫星、科学教育卫星和通信卫星。人造卫星可以根据地球的运动来定位,这种定位称为地球静止轨道定位。当卫星处于地球静止轨道位置时,其速度将相对较低,从而允许位置卫星移动。监测范围已在ITU-R Rec. S. 484中规定。关于运行固定卫星的控制区域公差限制小于±0.5°。在这种情况下,移动卫星需要大量的电力,并缩短了卫星的寿命。轨道位移时间间隔的预测涉及两种轨道方法,即Cowell法和Encke法。这两种方法都可以用来确定卫星移动时发生的时间长度。本研究旨在比较哪种方法可以更准确地确定时间间隔。本研究的优势在于,有两种方法可用于确定卫星轨道的时间间隔。通过在主控卫星上的比较应用研究,定量比较研究野外调查方法。两种方法的比较结果将用于轨道目的,并结合位置和数学因素来确定轨道移位的持续时间。
