摘要
基于直升机卫星通信系统的特点,分析了卫星通信系统中姿态角提取、坐标变化及抗遮挡等关键技术,采用链路分析估算方法,提出了针对关键技术点的测试方案设计,通过工程案例验证,实现了对系统的测试与评估。
Based on the characteristic of helicopter satellite communication system, the attitude of satellite communication system, the coordinate change angle extraction and anti-shielding technology are analyzed. Employing the link estimating method,the design of test plan is put forward according to the key technique points. Finally, the test and evaluation of the system comes true through the engineering case.
