November 2011 Meeting Summary

Both Mr. Stansell’s and Dr. Galyean’s spoke to the Southern California Section about An Update on LightSquared Technical and Politico-Legal Status on Tuesday, November 22th 2011 at NavCom Technology. There were 31 in attendance. A brief bio and abstract of the talk follows.

Abstract of Mr. Stansell’s and Dr. Galyean’s talk: (LightSquared Presentation Slides)
Last March, Tom gave the So. Cal Section of the ION a comprehensive overview with considerable technical detail on the probable effects on GPS of the proposed FCC waiver for LightSquared’s use of L band spectra. Since that time, LightSquared, the GPS industry, DOD, DHS, FAA, and NASA, to name a few of the agencies involved, have conducted tests and separately filed reports with the FCC and/or NTIA, which is the spectrum manager for federal agencies

Some of those reports have been released while others have not. However, much is known about the general outcomes and testimony to Congress by various interested parties, like General Shelton, Commander of the USAF Space Command, representatives of NTIA, FCC, user and industry groups and LightSquared have made headlines and have been seen on CSPAN.

The intense public relations activities and media attention that have surrounded this issue have often diverted attention from the publicly relevant issues such as the trade-offs between the need for lower cost broadband internet and wireless service and the integrity of GNSS systems.

Tom has been prominent in leading panel discussions on this subject with all four sides represented (GPS users, GPS industry, the regulators and LightSquared) and Paul has led the NavCom and John Deere intensive and extensive modeling, analysis and testing work and is a member of working groups on the subject. Like Tom, Paul also has considerable collateral knowledge of the dynamics of the regulatory processes and advises John Deere accordingly.

The information and insights these two leaders can give us will help us to understand the issues beyond the technical factors but including such as well; these technical issues have become clearer with the testing programs and more complex at the same time. For instance, LightSquared has formally proposed to the FCC that they modify their original frequency plans and power distributions for some period of time to allow the user environments and equipment to evolve into compatibility with the LightSquared signals. Another instance of the increased complexity is that one prominent GNSS supplier claims that LSQ is a boon to GNSS and that they have affordable filters which will immediately mitigate the effects of (at least) the currently proposed spectrum usage by LightSquared.

We expect a much more balanced and meaningful understanding of the then-current state of play for our members after this dual presentation.

Capsule Biography of Tom Stansell:
Tom Stansell heads Stansell Consulting. He spent 8 years with the Johns Hopkins Applied Physics Laboratory, 25 years with Magnavox (Staff VP), and 5 years with Leica Geosystems (VP). In those roles he pioneered Transit and GPS navigation and survey products. He has served on the WAAS Independent Review Board (2000); led technical development of the GPS L2C signal (2001); and coordinated the GPS L1C project (2004 – 2006).

He is a member of International Compatibility and Interoperability Working Groups and supports ICG activities for the U.S. State Department.

Awards and Honors:
ION Awards: Weems Award (1996), Fellow (1999), Kershner (PLANS-2000), GPS JPO Navstar Award (2002), and Johannes Kepler (2003).

Tom was technical chair (’84, ’86, and ’88) and general chair (’94, ’96, and ’98) of PLANS conferences, technical chair of ION GPS-91, and general chair of ION GPS-92. He is a past ION Western Regional VP.

Capsule Biography of Paul Galyean:
Paul is Director of Advanced Engineering at NavCom Technology, a subsidiary of Deere and Company. Prior to his service at NavCom and John Deere, he worked at Leica and Magnavox in integrated navigation systems. His satellite navigation experience reaches back into the Transit (NNSS) era and he has developed systems and receivers for aircraft, marine and land PNT applications. At NavCom, he managed the development of a certified aviation receiver and the development of the technology used in current Deere and NavCom products. He has managed the StarFire network, which provides Deere users with sub-decimeter-level navigation. He was recently the lead for the High Precision team in the FCC-mandated testing of LightSquared interference with GPS. He holds a PhD in Mathematics from UCLA.
