EXPANDING GLOBAL NAVIGATION SERVICEScourts. Thus maritime users have a strong feeling thatGPS is <strong>for</strong> maritime navigation.79However, <strong>the</strong> largest growth in GPS use is in <strong>the</strong>automotive area. There are about 650 Millionautomobiles in <strong>the</strong> world. By <strong>the</strong> year 2025 <strong>the</strong>re willbe 1 billion cars, most <strong>of</strong> <strong>the</strong>m with a GPS receiver. Sothis mode <strong>of</strong> transportation justifies attention asinternational laws and regulations are established <strong>for</strong>GNSS.80Railroad authorities, such as <strong>the</strong> U.S. FederalRailroad Administration, are very actively promoting<strong>the</strong> use <strong>of</strong> GPS to monitor <strong>the</strong> location and speed <strong>of</strong>trains in order to improve <strong>the</strong> safety and efficiency <strong>of</strong><strong>the</strong> railroads. With wider availability <strong>of</strong> DGPSthroughout <strong>the</strong> <strong>United</strong> States, <strong>the</strong> beneficial effect <strong>of</strong>GPS on this mode <strong>of</strong> transportation exists and justifiesattention.Availability <strong>of</strong> accurate land surveys through GPSis altering <strong>the</strong> surveying business, saving cost <strong>of</strong>construction material and <strong>of</strong> labor, and producinggreater accuracy81. The surveying business depends onaccuracy, so that any aspect <strong>of</strong> GPS that will promotethat is <strong>of</strong> interest to <strong>the</strong> surveyors. Land surveyingaffects <strong>the</strong> law <strong>of</strong> conveyancing. GNSS -generated landsurveys generally are considered to be legally au<strong>the</strong>nticand are legally acceptable to courts and o<strong>the</strong>r tribunals.Agriculture, <strong>the</strong> fishing industry, recreationinterests, telecommunications, outer space navigation,all have an active stake in GPS laws and regulations.They do not want to be left out or overshadowed by anyone mode. They want to be part <strong>of</strong> <strong>the</strong> community that<strong>for</strong>mulates <strong>the</strong>se laws and regulations.79 See IMO Resolution A.815(19 on WorldwideRadionavigation System, adopted on 23 November 1995, andIMO Resolution A.860(20) on Maritime Policy <strong>for</strong> a FutureGlobal Navigation Satellite System (GNSS), adopted on 27November 199980 See Washington Post, supra n. 1081 Larsen, Use <strong>of</strong> Global Navigation Satellite System (GNSS)Evidence <strong>for</strong> Land Surveys: Legal Acceptability, 38 Coll. on <strong>the</strong>Law <strong>of</strong> <strong>Outer</strong> Space167In conclusion, while each mode may view GNSS as<strong>the</strong>ir issue, GNSS clearly is multifaceted. There isdanger <strong>of</strong> conflict between differing operating principles<strong>for</strong> GNSS. The larger GNSS constituency, ra<strong>the</strong>r thaneach modal constituency, could more effectively achieve<strong>the</strong> general principles. The same reasoning applies toliability. The maritime, rail, automotive users and <strong>the</strong>farmers, fishermen and surveyors would certainly beunhappy to learn that <strong>the</strong>y could not recover <strong>for</strong>negligent GNSS, but that airlines could.Opportunity exists <strong>for</strong> a multi-functionalinternational body such <strong>the</strong> UN Committee <strong>for</strong> PeacefulUses <strong>of</strong> <strong>Outer</strong> Space to adopt multi-functional GNSSlegal principles. The alternative may be that we may areleft with piecemeal, conflicting GNSS legal principles.To support COPUOS multi-functional legal principles,coordination <strong>of</strong> legal principles and technical standardsamong <strong>the</strong> regulatory organizations (ICAO, IMO, ando<strong>the</strong>rs) is desirable.Commentary PaperJiefang HuangLegal <strong>Office</strong>r, ICAOI wish to <strong>of</strong>fer my congratulations to Pr<strong>of</strong>essor PaulLarsen <strong>for</strong> <strong>the</strong> excellent paper presented by him. I amparticularly thankful to him <strong>for</strong> his kind referencesthroughout <strong>the</strong> paper to ICAO’s work in this field.Indeed, in this decade, <strong>the</strong> International Civil AviationOrganization has dedicated a large portion <strong>of</strong> its workto <strong>the</strong> implementation <strong>of</strong> CNS/ATM systems, in whichGNSS is one <strong>of</strong> <strong>the</strong> key elements. Among o<strong>the</strong>r things,ICAO has organized two worldwide conferences <strong>for</strong>this purpose. The first was <strong>the</strong> Tenth Air NavigationConference held at <strong>the</strong> headquarters <strong>of</strong> ICAO inMontreal, Canada, in September 1991, which wasattended by 85 States and 13 internationalorganizations; <strong>the</strong> second was <strong>the</strong> World-wideCNS/ATM Systems Implementation Conference held inRio de Janeiro, Brazil, from 11 to 15 May 1998, whichwas attended by 123 States, 27 international
