摘要
针对低轮廓车载卫星通信天线由于受载体的扰动,在无航向和跟踪器的指引下,将很难保证天线稳定的指向目标的情况,提出一种新型的低轮廓车载通信天线控制系统和跟踪策略,使用倾角仪,补偿车体在天线俯仰波束正交的两个方向的倾斜,使用速率陀螺,通过软件实现了车体扰动的隔离以及航向隔离,解决了车体运动中实时准确跟踪的关键问题,提高了车载卫星通信天线的性价比。并用工程实例验证该方法的正确性。在城市路面,卫星不被遮挡的情况下,车载卫星跟踪系统可稳定接收卫星数字电视节目。
For carrier shaking, the low outline carborne satellite communication antenna is very hard to point to the aim satellite without the course and tracker. The paper describes a new track method for the carborne satellite communication antenna with low outline, which resolves the question. The method using inclinometer to compensate the incline of the antenna beam decussation direction and using velocity gyro to insulate the carrier shaking and course with software, which reduce the cost of the carborne satellite communications antenna. The paper also proves the correctness of the method through engineering examples. Without shelter, the carrier satellite communication system can accept the digital TV program stably on the city road surface.
