GVF562E-IMA: Operating the Sea Tel IMA Series Marine VSAT

Course details

Summary
  • Specific knowledge and skills for crew responsible for operating and monitoring a Cobham SeaTel IMA- series marine VSAT terminal at sea, including the Series 12 and GX antennas.

Description

Necessary knowledge and skills for technicians responsible for operating and monitoring a SeaTel IMA-series VSAT terminal at sea, such as the Series 12 and GX antennas.. (i.e., is equipped with an MXP control unit). Note: Choose GVF 562 if you are operating an '09-series terminal (i.e. is equipped with a DAC 2202 or similar control unit control unit).

Animation and simulator-based interactivity are used throughout the course to explain critical skills and concepts.

Why should VSAT operators be trained?

Marine VSAT terminals offer global broadband coverage to ships at sea. But for maximum up-time, crew members must be able to perform critical ongoing operational tasks after the installation technician has departed.

Audience:

This course is ideal for all radio operators, IT technicians, or other crew members who are responsible for operating and monitoring a SeaTel IMA-series VSAT terminal system while underway, as well as field engineers who will be continuing on to the GVF 503E series courses for installation and maintenance.

Certification:

Students who successfully complete this course are awarded the Marine Satcom Operator: Sea Tel IMA Specialist Certification.

Prerequisites:

GVF 561

Reference materials included:

Students may download and keep the exclusive SatProf SeaTel ’09 series troubleshooting flowchart for operators.

Delivery:

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.
