GVF562T: Operating the SpaceTrack Marine VSAT

Course details

Summary
  • Specific knowledge and skills for crew responsible for operating and monitoring a SpaceTrack 4000 marine VSAT terminal at sea.

Description

SpaceTrack marine VSAT terminals are stablized antennas now manufactured and supported by SpeedCast and previously by Harris CapRock and Schlumberger.

In this course, you will learn fundamental aspects of how to monitor, operate, and perform at-sea maintenance of SpaceTrack 4000 and 4000E series marine VSAT terminals. Topics covered include hardware components of the SpaceTrack VSAT terminal, principles of operation of the terminal, startup and shutdown procedures, operating controls using the front panel or built-in web pages, satellite modem operation, operator-level troubleshooting, and preventive maintenance. 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 SpaceTrack 4000 or 4000E VSAT terminal system while underway, as well as field engineers who will be continuing on to the GVF 503T series courses for installation and maintenance.

Certification:

Students who successfully complete this course are awarded the Marine Satcom Professional: SpaceTrack 4000 Specialist Certification.

Prerequisites:

GVF 561

Reference materials included:

Students may download and keep the SatProf SpaceTrack 4000 Operators Handbook.

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.
