    • Systems and methods for determining a positional state of an airborne array antenna using distributed accelerometers are described. One such method includes receiving and formatting acceleration data from each of a plurality of accelerometers mounted at different locations along the array antenna, receiving position and orientation data from an inertial navigation service (INS) mounted on the array antenna, generating an INS estimated position for each accelerometer based on the position and orientation data from the INS, generating an accelerometer estimated position for each accelerometer based on the acceleration data, determining a position and orientation of each accelerometer based on the respective INS estimated position and the respective accelerometer estimated position, determining an estimated position of a center and an orientation of the array antenna based on the determined position and orientation of each accelerometer, and adjusting a direction of the array antenna based on the estimated position of the array antenna.
    • 描述了使用分布式加速度计确定机载阵列天线的位置状态的系统和方法。 一种这样的方法包括从安装在阵列天线的不同位置处的多个加速度计的每一个接收和格式化加速度数据,从安装在阵列天线上的惯性导航服务(INS)接收位置和方向数据,产生INS估计位置 基于来自INS的位置和取向数据的每个加速度计,基于加速度数据生成每个加速度计的加速度计估计位置,基于相应的INS估计位置和相应的加速度计估计位置确定每个加速度计的位置和取向,确定 基于所确定的每个加速度计的位置和方位的阵列天线的中心和取向的估计位置,以及基于阵列天线的估计位置来调整阵列天线的方向。
