GVF521: Practical Technique for VSAT Professionals

Course details

  • Knowledge, techniques, and practical tips that every field technician and installer needs to know in order to perform a high-quality, reliable VSAT installation job.


As the follow-on course to GVF510 (Core Skills) and GVF520 (Satcom Fundamentals theory), GVF521 covers the range of knowledge, techniques, and practical tips that every field technician and installer needs to know in order to perform a high-quality, reliable VSAT installation job. Covers the range of practical tips, techniques, and knowledge taiolored for fixed-VSAT field technicians and installers, such as using a compass, calculating levels in dB, voltage drops, cable lengths, using a spectrum analyzer, grounding, basic IP networking, safety issues, and troubleshooting.


Courses GVF510 and GVF520 .


The course is appropriate for all installers and field technicians who may be responsible for activating any type of VSAT terminal.
