In recognition of twenty five years of pioneering meteorological work using radionavigation systems to determine winds in the atmosphere throughout the world, John Beukers received a citation and award from the Institute of Electrical and Electronics Engineers (IEEE). The award was presented at the Annual Awards Ceremony of the Long Island Chapter of the IEEE held at the Carlin Hotel in Huntington, N.Y. on April 22,1990. A fitting keynote address was given by Dr. Carlton Bayless, President of the 330,000 worldwide member Institute, who spoke of the challenges facing the engineering profession to clean up the environment to ensure that the planet remain habitable by mankind past the next century.

John Beukers was born in England and received his degree in Electronics Engineering at London University. He emigrated to the United States in 1957 and in 1963 started his own company, Beukers Laboratories, Inc. which specialized in radionavigation development and associated products. The company was subsequently sold to a Philadelphia manufacturer in 1985. John Beukers is still actively involved with radionavigation and is Secretary of the Wild Goose Association, a non-profit organization th at watches over and seeks to promote the use of the popular Loran-C navigation system used by many boat and aircraft owners.

WGA welcomes these new members Press Notice: The Department of Transport who have joined the Association since the beginning of March: April 24,1990

Allison, Ray P. Bellantoni, John F. Besant, Christophe After widespread consultation, it has been decided, in principle, to adopt Loran C as Cochran, A. R. the standard marine radionavigation system in UKwaters during the 1990s, Cecil Cosgrove, Burt Parkinson, Secretary of state for Transport, announced today. Fletcher, Harold K. Honey, Frederick J. Subject to satisfactory international agreement within an acceptable timescale, this Horsager, Jerry would mean replacing the current Decca Navigator System with the internationalcivil Huddleston, Steve Loran C system currently proposed for North West Europe and the North Atlantic. Jensen, Captain D. Jones, Dennis M. Answering a Parliamentary Question from Sir David Price MP (Eastleigh), Mr. Knauer, Timothy G. Parkinson said: Krammes, Lt. S. Lee, Graham N. "Following a lengthy period of public consultation and careful consideration, I have Litchford, George concluded in principle that,on technical and cost grounds, the balance of advantage for Lo, Ray the UnitedKingdomwould be to join the internationalcivil Loran C system currently Maceluch, Dr. John J. proposed for North West Europe and the North Atlantic.

It would mean closing down in 1997 the Viehweg, LCDR C. present widely respected UKDecca Navigator System, the origins of which date back Wilmert, Terry to the Second World War. The Decca System has been successfully operated by Racal Decca Marine Navigation Limited and its predecessors for several decades, and ...and during April and May: the marine community owes a considerable debt to the service, which is highly regarded. Belicka, Jr., John Boykin, Willie "I have had the benefit of a wide range of responses to the Department's consultative CEPIEC UNIV LIB - 1 document of June 1989. Many in the marine community, here andabroad, agree that CEPIEC UNIV LIB - 2 we should not be wholly dependent for marine navigation on non-European military CEPIEC UNIV LIB - 3 satellite systems such as the American Global Positioning System (GPS) andthe CEPIEC UNIV LIB - 4 Soviet GLONASS system and that a terrestrial civil alternative is needed. I am Char, Ronald K. satisfied that the Loran C system would meet the UK'snavigational requirements to Cox, Joseph acceptable technical standards and additionally would provide more extensive cover, Damiani, Thomas R. and be less affected by seasonal and night-timeerrors. Diekmann, Vernon Elazar, David "I have given particular consideration to the representations from the fishing industry Gannon, John who are concernedabout the costs of converting to Loran C. I fully appreciate the Johannessen, Rolf industry's extensive use of the Decca system for fishing, as well as for navigation, and I Jourdan, David have considered the industry's points very carefully. However, if we introduce Loran McDonald, Keith D. C, the fishing industry will gain some important benefits. Loran C's avoidance of Meyerhoff, IT, Paul seasonal and night skywave effects makes it a more consistentsystem .Moreover, a Nowicki, Steve Loran C system would allow significant cost reductions, which will work through as Rctko, Edward lower light dues paid by fishermen. In the meantime I will look specifically at the Schnauffer, Jr., Patrick M. light dues paid by fishermen at present, in light of representation they have made. Skaar, Rodney M. The fishing industry will also be aware that I am currently consideringa report by the Thomas, CW04 Burt J. British Ports Federation which recommends that pleasure craft should be brought Uppling, Byron R. into the light dues system, so as to share the costs falling on the General Lighthouse Winslow, Roger Fund. Wood, James M. Continued on page 10 Spring 1990 The Goose Gazette 11 UK Radionavigation: Continued from page 10 "Moreover, I am determined to ensure that there is a reasonable transitional period between Loran C becoming fully available and the Decca system being switched off.

"The UK will also be making it clcar to the other potential partners in the international agreement that our window for a decision in favour of Loran is time WGA Memberships limited. In the event of a firm commitment to Loran C, I would wish to give the marine community about six years notice of the ending of Decca transmissions. Available: Undcr Racal Decca's current contract with the general lighthouse authorities, the system could not continue beyond February 1997. I am also conscious of the need for TIIE WILD GOOSE ASSOCIATION an adequate transition period of at least three years during which both the Decca and P. 0.Box 556 Loran C systems would be operating. These constraints mean that a delay beyond Bedford, Massachusetts 01730 early to mid-1991 in ratifying an acceptable international agreement would, as far as can currently be seen, effectively rule out the UK's adoption of loran C. Thus, if a (516) 862-7500 firm agreement acceptable to the UK has not been rcached by then it would be my intention to wilhdraw from the international discussions and to consider with the general lighthouse authorities whether to arrange for modernization of the UK Decca Navigator System so that it could continue to operate beyond 1997. 12 The Goose Gazette Spring, 1990
