GVF503E: Sea Tel Marine VSAT Installation and Maintenance

Course details

Summary
  • Factory-authorized training for installation, commissioning, operation, and troubleshooting of a Cobham Sea Tel ’09-series 3-axis marine stabilized antenna system. Animation and 3-D simulator-based interactivity are used extensively to explain concepts and provide realistic skills practice for the student.

Description

Learn key aspects of how to install, commission, operate, and troubleshoot a Sea Tel ’09-series 3-axis marine stabilized antenna system through this online, self-paced, 3-D animated, highly interactive, simulator-driven course. Topics covered include principles of vessel motion, stabilized antenna operations, and SeaTel terminal details including configuring and monitoring techniques.

All equipment is explained, including the Sea Tel gimbaled mount, antenna and RF components, control system components, and navigation system connections. Details on satellite acquisition and tracking, mount balance concepts, operating modes, performing site surveys, installation and assembly, commissioning, maintenance, and troubleshooting are covered in depth.
