Solutions – Key Points

www.gvf.org

2002 – Responding to satellite operator members, GVF created a global programme to serve as

the international standard for VSAT installer certification training. Programme endorsed by the

international industry

2006 – Programme expanded with extensive online interactive content

2009 – Programme restructured at satellite operators’ request to expand its reach, and to more

sharply focus on mitigating uplink interference

Accordingly “GVF Basic Certification” awarded to students who can demonstrate core skills in

interference mitigation:

Accurate antenna pointing (to minimise Adjacent Satellite Interference)

Accurate cross-pol alignment (to minimise cross-pol interference)

Proper connector attachment (to prevent interference due to

rebroadcast/retransmission)

GVF Training Programme Background 1

www.gvf.org

The key aspect of Basic Certification is the entry-level online course GVF510 for which

the student is required to pass the simulator-based interactive pointing and cross-pol

exercises

On completion of GVF 510 and the Hands-on-Skills-Test (HOST) a technician will

understand the importance of interference mitigation and have the skills to do so

The HOST hands-on assessment is focused entirely on practical skills and allows an

experienced, GVF-approved technician/trainer to act as HOST examiner in the field

Students with the Basic Certification are assigned a unique GVF Certification

Identification Number, they are registered in the GVF Database, and their contact details

are accessible by satellite operators who may wish to confirm a field technician’s

certification status at the time of a new VSAT activation

GVF believes it is a practical goal to train EVERY VSAT TECHNICIAN to at least basic

Certification status, and to achieve this the satellite operator community has begun

implementation of a phased programme

GVF Training Programme Background 2

www.gvf.org

GVF offers Advanced Certification for students requiring thorough knowledge of

fundamental theory and practical technique

Online courses GVF520 Satcom Fundamentals

GVF 521 Practical Technique for VSAT Installers

Students who complete GVF 510, GVF520, GVF521, and HOST receive GVF Advanced

Certification and are eligible to be listed in the GVF Public Online Installer Database

Many students also take advantage of follow-up specialist Certification courses, which

currently include product-specific training for Gilat, Hughes, iDirect,

Schlumberger/HarrisCapRock, Seatel, and others.

The GVF Certification Programme is delivered in coordination with other organisations that

provide complementary training.

GVF Training Programme Background 3

www.gvf.org

GVF is coordinating with the satellite-operator community on implementation of a

phased plan to gradually prepare the marketplace for the day when Certification

becomes a requirement of the satellite operators… key features:

- Online training in multiple language options

- HOST taken with immediate testing availability, and in local language

- Operators’ staff become “Examiners” (authorized for HOSTs)

- Events to promote awareness of the importance of training

- When installers call a satellite operator to activate a remote earth station they’re

asked for their Certification ID number. If they do not have one, the satellite operator

encourages the installer to become Certified

- GVF follows-up with all technicians identified by the Operator as requiring training

- After an agreed-upon date Operators will require installers to hold a certification validated

by the Satellite Operators’ Interference Initiative group

- GVF supports verification of Certification by providing real-time access to a GVF-certified

database

- GVF offers tuition fee incentives to encourage widespread enrollment

www.gvf.org

The GVF Auto-Deploy Operator Certification Programme will

comprise three categories:

Satellite News Gathering (SNG)

Government Auto-Deploy (e.g. military)

Commercial Auto-Deploy (e.g. oil & gas)

Auto-Deploy Overview

www.gvf.org

GVF has begun to coordinate with the satellite-operator community on

implementation of a phased plan to gradually prepare the marketplace for the day

when Certification becomes a requirement of the satellite operators… key features:

- Online training in multiple language options

- HOST taken with immediate testing availability, and in local language

- Operators’ staff become “Examiners” (authorized for HOSTs)

- Events to promote awareness of the importance of training

- When auto-deploy operators call a satellite operator to activate a remote earth station

they’re asked for their Certification ID number. If they do not have one, the satellite

operator encourages the auto-deploy operator to become Certified

- GVF follows-up with all technicians identified by the Operator as requiring training

- After an agreed-upon date Operators will require auto-deploy operators to hold a

certification validated by the Satellite Operators’ Interference Initiative group

- GVF supports verification of Certification by providing real-time access to a GVF-certified

database

- GVF offers tuition fee incentives to encourage widespread enrollment

Auto-Deploy 1

Auto-Deploy 2

NOC Staff Training

As with VSAT Installation Training, GVF recommends that satellite operators provide auto-deploy training to NOC technicians and engineers:

Firstly, the GVF curriculum provides efficient training in satcom fundamentals that benefit NOC technicians’ job competences

Secondly, NOC technicians are the primary point of contact with auto-deploy operators in the field, and both will have a common training background

www.gvf.org

Auto-Deploy 3

NOC Contact with AD Terminal Operators

When an auto-deploy operator contacts a satellite operator to commission an AD terminal on that satellite operator’s platform, the satellite operator requests a GVF Certification ID number, which can be verified on the GVF database of Certified Auto-Deploy Operators

If an ID number is not available, the satellite operator can explain that they support the GVF-industry programme on Certification, and then invite the AD operator to visit the GVF training information resource at:

www.gvf.org

www.gvf.org

Auto-Deploy 4

Satellite Operator Contact with AD Operators’ Employers

Representatives of satellite operators’ management can advise auto-deploy operators’ employers of the Certification programme

The respective satellite operators shall approach the auto-deploy operators’ employers to explain that the GVF-industry programme is designed to increase QoS and decrease operational costs by improving the skills associated with auto-deploy operations.

The initiative is a major benefit to all parties

In some cases, the auto-deploy operators’ employers may be interested to have their own staff qualified as a GVF Examiner

• Now: Global Product Quality Assurance Framework

www.gvf.org

Product Quality Assurance Framework 1

Strategic Plan for a Global Satellite Industry Arrangementto Facilitate Earth Station Design & Production

1. Situational Analysis

Globally, many satellite operators are escalating deployment of Ka-band, Ku-band, C-band, X-band, L-band, and other systems, even as global demand increases for auto-deploy, “comms on the move”, maritime, sub-0.75m, and other transmitting earth stations that require a high degree of technical rigour in design, production, and performance

A significant number of satellite operators currently do not apply a product quality assurance programme

Compounding the problem, reduced terminal and installation fees, deregulation, increasing evidence of poor-quality manufacturers, increasing production volumes of small aperture/wide beam-width antennas, and other factors, are leading to a “perfect storm” of interference, not only for traditional C-band and Ku-band, but also for newly introduced Ka-band

www.gvf.org

Product Quality Assurance Framework 2

Strategic Plan for a Global Satellite Industry Arrangementto Facilitate Earth Station Design & Production

2. Background Phases

Phase 1 – Rigorous satellite operator in-house product quality assurance (PQA) programmes; satellite operators without their own programmes used other’s as a reference point to provide for the quality of earth station products used with their satellite platforms

Phase 2 – Many satellite operators withdrew from in-house PQA, reportedly to reduce operational costs; vacuum partially filled by GVF, industry-endorsed, out-sourced product testing; GVF still provides this, but use of the programme has been limited due to lack of industry resolve to return to PQA

Phase 3 – Industry now experiencing major financial losses through signal interference, some of which caused by insufficient product quality; satellite operators now support a global industry PQA framework; GVF Mutual Recognition Arrangement Working Group (MRA WG) working with industry

www.gvf.org

Product Quality Assurance Framework 3

Strategic Plan for a Global Satellite Industry Arrangementto Facilitate Earth Station Design & Production

3. GVF MRA & PQA

Through the collective view of GVF (shortly after its foundation in 1997) the satellite industry identified as a problem the redundant testing requirements required of equipment manufacturers who sought type approvals from multiple satellite operators

The solution was created in 1999 by global industry consensus through the GVF MRA WG, with the Mutual Recognition Arrangement reducing costs and improving industry efficiency
