“Genesis of GVF Training in SE Asia” Christopher Sivertz

Starting in 1995, Dave (‘Whirlwind’) Hartshorn and I (working out of Singapore for SSE & Prodelin, respectively) witnessed, first-hand, the “explosion” of TDMA-Voice VSAT networks here in South East Asia. 1.8m antennas (C-Band, Linear-Polarised) were being frantically installed in (then) very remote locations. The installers lacked training in the pitfalls associated with Cross-Pol, Pointing, Over-drive, and IFL cabling/connector issues.

The Network Operators recognised these pitfalls and asked for our help in the form of training that is practical for installers in Indonesia, Thailand, etc. Enter Ralph Brooker in 1999 to provide hope. The suite of SatProf/GVF on-line courses continues to expand whilst eliminating many of the language, cultural, and distance challenges of training that face network operators in South East Asia.

As a Satcom Systems Engineer, not a day goes by without me thanking Ralph, Dave, and all the others who have made the SatProf/GVF Training so valuable to our customers in this region of the world.
