The objective of this method is to develop a control strategy under blocked and shadowed conditions for the SOTM system that points the antenna line of sight to the satellite using a closed-loop tracking based on the received signal power. This estimation ensures a fast reacquisition of the target satellite after signal blockage and that the transmitted data be cached in time to avoid the real-time collected data lost during blockage. The basic principles of the method can also be applied to the SOTM system at other bands, such as Ka band.
