ASC704: Administering and configuring NGC tracking systems

Course details

  • Operation, maintenance, and performance tuning of the CPI NGC controller for fixed, motorized antenna applications.


This course is intended for earth station administrators who are responsible for the overall operation, maintenance and performance of NGC-controlled antenna systems. A typical fixed, motorized 4.9m antenna system is explained in detail, and variations and options are described.


Earth station administrators who are responsible for the overall operation, maintenance and performance of NGC-controlled antenna systems. Techs and engineers who will be contininuing with higher level NGC training courses.


Recommended: GVF 530+531+532. Required: ASC 701 + 702..


Animated & interactive HTML/Flash, self-paced, on-line format. Requires Internet access while studying the course material. High speed access is preferred but is NOT required. Student's computer must have a current browser and the current version of the Adobe Flash player (free) installed.
