“…Satcom-on-the-Move (SOTM) refers to the installation of satellite signal antennas on moving carriers, which can control the direction of the antenna to align with the communication satellite in real-time during the movement of the SOTM carrier, thus achieving a stable transmission link between the satellite and SOTM [1][2][3][4]. With the development of technology, satellite communication is becoming increasingly widespread [5][6][7][8].…”

When the carrier of the Satcom-on-the-Move (SOTM) antenna is in a high maneuvering state of motion, the accuracy of the array antenna beam pointing towards the satellite may decrease, which may cause a decline in communication effectiveness for SOTM or even cause the antenna to deviate from the target satellite and lead to communication interruption. This paper proposes a multi-beam searching and capturing method for SOTM array antennas, which divides the array antenna into multiple parts to form multiple independent and controllable sub-beams. When the SOTM carrier is in a high maneuvering state of motion, multiple sub-beams are obtained by dividing the array antenna, thus obtaining multiple points in the radiation pattern. We designed an optimal pointing analyzer, which calculates the SOTM array antenna beam direction based on whether the SOTM antenna is pointing towards the satellite and utilizes different approaches for processing. Experimental verification was conducted for the proposed scheme. The experimental results show that if the antenna beam does not lose the satellite, the proposed scheme can obtain better communication quality compared to conventional schemes. If the SOTM antenna beam loses the satellite and causes communication interruption, the proposed scheme in this paper can capture the satellite faster than conventional schemes. The experimental results demonstrate the effectiveness of the proposed scheme.

“…Consequently, the SCAS system cannot be applied to moving carriers such as aircraft, cars, ships, etc., due to the position and attitude of the carrier constantly changing during the movement. In order to overcome the disadvantage of the SCAS system, a system that realizes satellite communication while the carrier is in motion has appeared in the field of satellite communication, which is usually called the "Satcom-On-The-Move (SOTM)" system [9,10]. algorithm is designed for tracking satellites with the SOTM antenna when the carrier is in a high maneuvering state.…”

Using Satcom-On-The-Move (SOTM) antenna on moving carriers to track communication satellites is a rapidly developing technology. The normal running of the SOTM system requires its antenna beam to track the target communication satellite accurately at all times. However, due to the errors of the measurement system, tracking deviation will inevitably occur, especially when the moving carrier is in ahigh maneuvering state, which may cause communication failures. In this paper, we propose a synthetic deviation correction algorithm; when the carrier is in the high maneuvering state, the measurement error is converted into the deviation of the azimuth as well as the pitch of the antenna that needs to be corrected to correct the pointing of the SOTM antenna. Finally, the proposed algorithm is verified by experiments. The experimental results show that the proposed algorithm has a good isolation effect on the high maneuverability of the carrier, which means that the pointing to the communication satellite is more accurate and achieves better communication quality under the high maneuvering state. The effectiveness of the algorithm is illustrated.

“…The radiating elements were designed in view of their integration in a dual-band beam steering array implemented through the chips introduced in [13]- [15]. As discussed in [21], the proper implementation of this type of architecture requires adopting a complex multilayer stack-up comprising different types of vertical transitions.…”
