TIW 系统公司开发了一种供遥测、跟踪和通信天线用的现代化、模块化、紧凑的天线控制器(ACU)。该控制器兼有天线控制单元、位置变换/显示机箱和极化控制单元的功能。通过插入印制电路卡,就可以加上跟踪接收机、自动相位控制单元、跟踪合成器和其他功能。根据需要,接收机可以是简单的宽带步进接收机,也可能是全功能的锁相环(PLL)自跟踪接收机。过去,这些功能要占据全部设备机柜的很大部分。本装置使用现代微处理机技术,对天线位置和速度进行数字控制。将外部计算机(PTIC)和 ACU 的一个串行口相连,能实现先进的跟踪状态和遥控功能。PTIC 还通过使用高分辨率彩色图形和易懂的菜单为用户提供方便的操作员接口。
TIW Systems has developed a modern, modular, compact antenna controller (ACU) for telemetry, tracking and communications antennas. The controller combines the functions of an antenna control unit, position change / display housing and polarization control unit. By inserting a printed circuit card, you can add tracking receiver, automatic phase control unit, tracking synthesizer and other features. Depending on requirements, the receiver can be a simple broadband stepper receiver or a full-featured phase-locked loop (PLL) self-tracking receiver. In the past, these functions took up a large portion of the entire equipment rack. The device uses modern microprocessor technology to digitally control the position and speed of the antenna. Connecting an external computer (PTIC) to a serial port on the ACU enables advanced tracking and remote control functions. PTIC also offers users a convenient operator interface by using high-resolution color graphics and easy-to-understand menus.
