The automatic system satellite signal strength tracking model through the positioning of the receiving antenna is one way to reduce the problem of attenuation and signal strength instability which is quite influential in tracking the satellite orbit position. The method of applying the antenna movement technique by adjusting the azimuth and elevation angles is possible to detect the position of the satellite orbit trajectory accurately. Therefore, the expected goal is to know the existence of the satellite's orbital trajectory and ensure that the signal strength it transmits will always be stable in all conditions. The empirical quantitative method is used to support the achievement of these objectives where the technique is carried out through field observations and device design involving calculations and applied mathematical equations based on information on satellite position data as a tracking object as well as a source of signal strength. Based on the test results, it shows that all the positions of the tracked satellite orbital trajectories produce a minimum and maximum azimuth-elevation angle of 0.52% -4.02% and 0.25% -3.99% when the system detects NSS6. Furthermore, when the system detects Palapa D, the minimum values for the percentage of maximum deviation error are 0.6% and 4.67% with a tolerance of the alignment angle to the satellite of < 20. Overall, the designed system is able to track the position of the satellite's orbit path based on the level of signal strength stability on the parabolic receiver antenna which is designed with small percentage of angle error.
The model of tracking the automatic signal strength of the system through the receiver antenna is one way to minimize the attenuation of the receiving signal through automatic antenna movement techniques based on information data input the value of the azimuth and elevation angle between the satellite and receiving antenna. The purpose of this research is to ensure the existence of satellite orbit trajectories, and the signal strength emitted will always be stable in each orbit position. While the method used in this research is field observation and design system with position of satellites as target objects tracking of the signal strength to designed device which located as a receiving antenna and tracker device. Analysis and measurements results showed that all satellite targets tracked resulting in a minimum to maximum angle of azimuth and elevation have percentage errors 0.52% - 4,02% and 0.25% - 3,99% when detecting NSS6 while when detecting Palapa D the value minimum to maximum percentage errors were 0,6% and 4.67% with a tolerance of directing angle to satellite < 2° according ITU-R recommendations. The conclusion is that satellite objects can be tracked the position of the orbit by looking the level of strong consistence of the received signal quite well based on the results of small angle error detection.
