The sat-nms MANTL24 antenna developed at SatService Company is a fully electrically motorized 2.4m L-band antenna. The antenna can be electrically positioned into elevation and azimuth via web browser, HTTP protocol via TCP/IP or serial interface with an ASCII protocol. However, if a beacon receiver cannot be connected directly to the antenna control unit, only program tracking mode can be supported manually. In this paper, we introduce an automatic tracking control and data evaluation program to monitor a GNSS signal quality seamlessly without a beacon receiver. Developed program is composed of serial communication frame, HTTP connection frame, user interface frame, and main frame and uses received target satellite elevation and azimuth data for real-time automatic satellite tracking.
