Core Skills for VSAT Professionals
Critical skills required for fixed-antenna VSAT field technicians and engineers, focusing on accurate antenna alignment and prevention of major sources of uplink interference.
Course Description
Improper installation technique is a major cause of interference, which degrades satellite transponder performance for all users. Developed in coordination with major satellite operators, GVF 510 teaches technicians the correct way to point an antenna, align cross pol, attach connectors, and decommission terminals – four leading causes of avoidable interference. As the first step towards GVF Satcom Professional Certification, GVF 510 teaches and evaluates the core skills that all VSAT field technicians must have – regardless of the type of equipment they install.
Includes advanced interactive 3-D simulations. Second edition: updated, includes new cross-pol and other simulators.
Prerequisites:
Basic knowledge of DC and RF theory. GVF 505 and 506 recommended.
Audience:
All installers, field technicians, and engineers who may be responsible for activating any type of VSAT terminal.
Delivery:
Animated & interactive HTML5, self-paced, on-line format. Requirements: internet access while studying the course material (high speed preferred ); current browser with JavaScript enabled; permission to access SatProf server and learning system websites; mouse.
Languages:
English only (limitation of HTML5 conversion).
Tests:
Each lesson contains a mandatory quiz and simulator-based skills assessments. All pages must be viewed and all quizzes and simulator tests must be passed in order to satisfactorily complete the course.
Certification:
Students who pass this course and the GVF Basic Hands On Skills Test will receive the GVF Basic Satcom Professional Certification. This course is also required as a pre-requisite for the GVF Advanced Satcom Professional certification and all GVF Satcom Professional Specialist certifications.
