About us

SatProf was founded by satellite ground system engineering industry veterans to meet the need for accessible training for satellite communications technical professionals. For a list of papers and patents we have authored, please see the Technical Resources page.

Ralph Brooker, President

Prior to co-founding SatProf, Mr. Brooker held technical and management positions at Andrew, Microsource, Amplica, and Comsat Laboratories. His experience includes microwave integrated circuit and subsystem design, hardware and software engineering management, new product introduction, CAE/CAM software, production and process engineering management, VSAT system engineering, link and network planning, large earth station international project management, technical market research, new product definition and startup, and simulation software for nonlinear amplifier distortion and antenna pointing error network effects. Mr. Brooker chaired the Global VSAT Forum’s Mutual Recognition Arrangement Working Group which defined the process for industry-recognized earth station type approvals. He has five issued patents and several publications, and received an M.S.E.E. from the University of Illinois in 1981. Read more …

Pete Zilliox, Vice President

Mr. Zilliox has 34 years satellite industry experience, including spacecraft flight hardware engineering, ground communications equipment (GCE) design and manufacturing, earth station system design, end-to-end system design, system field installation integration and test (II&T), and profit and loss business management.

He has been with Hughes Aircraft Company (now Boeing Space and Comm), Collins Radio (now Rockwell International/Alcatel), Dalsat, Zilliox & Associates, and Andrew Corporation.
