The Model 881A Azimuth Drive is a rugged and powerful rotary actuator drive that can be coupled to an Imagenex Model 881A Profiling Sonar. The two axes of rotation in this combined unit provide the capability to obtain accurate, high resolution range information in any direction. In standard applications, profiles may be made in any direction by simply commanding the Azimuth Drive to rotate the attached profiling sonar anywhere in a circle. The profiling sonar can then perform a cross-sectional scan before being rotated to a new azimuth angle. The Azimuth Drive uses the same RS-485 serial communications line and command structure as the profiling head. A single, simple to use PC compatible computer program operates both, and full communications protocol specifications are provided for designing customized software.
该模型是一个崎岖881a方位驱动强大的旋转致动器的驱动，可以连接到一个Imagenex模型881a剖面声纳。在这两个转动轴组合提供的功能来获得准确的，在任何方向的高分辨率范围的信息。在标准的应用程序，配置文件可以通过简单地控制方位驱动转动连接的剖面声纳一圈在任何地方任何方向。剖面声纳可以进行横断面扫描之前被旋转到一个新的方位角。方位驱动使用相同的RS-485串行通信线路和指挥结构作为分析的头。一个单一的，易于使用的PC兼容的计算机程序操作，和完整的通信协议规范提供设计定制软件。
