Hinson Administrator, Federal Aviation Administration Dear Mr. Hinson: We have been conducting a review of civil applications for the Department of Defense's (DOD) Global Positioning System (GPS), including the Federal Aviation Administration's (FAA) plans for using GPS. The purpose of this correspondence is to bring to your attention observations we have about these plans as they relate to two existing navigation systems--the Very High Frequency Omnidirectional Range/Distance Measuring Equipment (VOR/DME) and LORAN-C. On June 9, 1993, FAA approved GPS as a supplemental means of navigation for most phases of flight. The agency plans to rely eventually on a satellite-based system, including GPS, as the primary means of navigation for all airborne transportation. These plans appear to lessen to some extent the importance of VOR/DME and LORAN-C in future airborne navigation. We understand, however, that FAA is continuing with the process of implementing plans to expand these two systems. While we have not reviewed these two programs in depth, we believe that a reassessment of the need to expand the VOR/DME and LORAN- C systems presents FAA with a good opportunity to identify items of lower priority whose funds can be used for more critical purposes. VOR/DME EXPANSION Expansion plans for the VOR/DME system date back several years, when development of GPS for civil application was still in its infancy. Currently, the VOR/DME network consists of units in about 950 locations nationwide, with the last unit installed in 1983. In 1986, FAA developed a national network plan that called for 59 new locations. In 1989, FAA reassessed its needs and determined that 70, rather than 59, new locations were needed. In September GAOIRCED-93-211R, VORIDME and LORAN Expansion -,a.,-
