|
The Ministry of Maritime Affairs and Fisheries in Korea completed the installation of 8 maritime DGPS stations and is to going install 3 additional Maritime DGPS stations for the enhancement of dual coverage in Korean coasts until Oct. 2002. Moreover, Korean government decided to provide the NDGPS service over the whole Korean inland area, which will be scheduled to complete until June. 2004. On this paper to evaluate the possibility of using maritime DGPS site as an element of NDGPS ana to evaluate the required number of additional NDGPS sites, the propagation characteristics of the radio waves of 300㎑ bands on sea and land path are studied With the result of study, the conceptional design of Korean NDGPS System is proposed, which consists of 5 NDGPS sites with modified antenna and three coverage monitoring sites. |
