Abstract:

with the gradual maturity of both the mobile communication control and antenna technology and the gradual increase of users" demand for aviation Internet, a Ku/Ka dual-frequency and dual-antenna control system was designed based on the experience of aviation manufacturing and satellite communication technology. The system can quickly complete the function of the Ku and Ka antenna pointing to the satellite and satellite switching in different regions according to the airborne computer control instructions, thus can ensure the normal link communication, as well as providing the aviation users with multi-level communication service support with the best bandwidth service concept. The system adopts the size lightweight design method. With the combination of high precision servo control technology, the fast satellite switching technology and the high dynamic tracking technology, the fast dynamic response of the system and the accurate satellite pointing ability as well as the satellite tracking ability can be achieved. The system is designed in strict accordance with the military product development process. The prototype development and ground related tests have been completed, and the technical indicators are in line with the previous design.
