“…The signal strength, when moving in one axis, has a parabolic shape. This dependence of the signal strength on the angle of rotation results from the characteristics of the parabolic antenna for tracking the satellite signal [5]. The specific parameters of this signal strength characteristic can change, depending on weather conditions, antenna polarization or defocus, but the general shape and its symmetry stays the same.…”

The article presents an improved satellite tracking approach using the extended Kalman filter within the control systems of the moving antenna. The main focus is on the issue of maintaining the maximum signal strength during vehicle movement, gyroscope and GPS sensors error and the deterioration of reception due to changing conditions (weather, obstacles). Typically used techniques are based on ad-hoc scanning of the maximum value of the RF signal. The approach presented in this article might be used as a much more consistent and elegant alternative to these algorithms. To prove the function of the presented algorithm, simulations of several different scenarios are performed. Based on these simulations, the robustness and speed of the newly designed algorithm are evaluated.

“…This system has been implemented for NASA's Deep Space Network antenna that has also been applied for signal‐to‐noise ratio at Ka‐band frequencies. In [11], the antenna performance has been improved using the sub‐reflector focus excursion technique. A method to transform the antenna error from 3D coordinates to 2D antenna coordinates for improving monopulse control accuracy is proposed in [12].…”

Shipborne satellite earth stations will cause feed vibrations when the conical scanning frequency is too high under low dynamic conditions, which will cause large fluctuations in the received signal strength of the earth station in a relatively stationary environment. And too low conical scanning frequency will cause the earth station Lost the target satellite in a high dynamic environment. The tracking system adopts adaptive speed regulation strategy and initial phase estimation algorithm, and adjusts the frequency of cone scanning in real time according to the motion attitude of earth station measured by IMU, so that the earth station can adapt to different dynamic environment. In practical engineering, a Ku band tracking system of ship borne satellite earth station is designed and implemented based on FPGA. The actual test results show that the signal fluctuation of the improved cone scanning algorithm is about 2dbm lower than that of the cone scanning algorithm with a fixed frequency of 50Hz.
