About me
I have 25 years of experience in the satellite communications field planing, testing, installing, configuring, and maintaining equipment.

I have worked 5 years for O3b Network as the Lead Test Engineer. During this time I developed test plans, reported to management on the status of the projects in the lab, designed a new lab to support simultaneous testing of RF equipment, software development, and firmware testing. I also helped managed the work flow through the lab, managed resources, and developed procedures for the lab.

The 12 years that I worked at the Mount Jackson Earth Station under several owners. While working at Mount Jackson, we went from a single router to a Cascade/Lucent frame relay and ATM network to a small Cisco network.
I have a good understanding of RF, L-Band, Frame Relay, ATM (OC3-OC12), DVB, DVB-S2, DVB SI tables, Data Standards (DS3, T1, V.35, RS485/442/232, X.21), IPv4, IPv6, Ethernet, Firewalls, Windows, and Linux.
I have experience with test equipment including Scalar Network Analyzers, RF Link Simulators, Packet Generation and Analysis, Spectrum Analyzers, Power Meters, Signal Generators, Oscilloscopes, Data Analyzers, Protocol Analyzers, Test loop Translators, and more.
