抄録: In order to put hybrid navigation with GPS and Loran C into practice, and to measure basic data for the accuracy of position fixes by Loran C, we evaluated the relative error between the position fixes obtained by the simultaneous measurement with GPS and Loran C at a fixed station (Nagasaki University) on the land. There was constant error of about 600m southerly on Loran C. And the differences in distance from the observation position on Loran C to the relative position on Loran C to GPS in the case where the datum position was GPS were 30~60m on 3D (three-dimensional positioning) and 2D3 (two-dimensional positioning with three satellites). But there were distance differences of 0.1~0.2 nautical miles on 2D2 (two-dimensional positioning with two satellites). When we corrected the GPS position by the displacement obtained from the observation at a fixed station and calculated the distance difference from the observation position on Loran C to the relative position on Loran C to GPS correction position, their errors were 10~40m except in the case of the middle level positioning of 2D2.
