Open-File Report 98-791: Physical Characteristics of Dungeness Crab and Halibut Habitats in Glacier Bay, Alaska

Navigation Systems

The 1997 Glacier Bay survey was navigated with a Leica Differential Global Positioning System (DGPS) which provided a position with accuracy of 1-5 m in DGPS mode. At times during the cruise, differential signal was interrupted. In non-differential mode, the receiver provided a position with 30-50 m accuracy. A KVH Industries Inc. azimuth digital gyro-compass provided ship headings with 0.5 degree accuracy. Navigation data were recorded using Yo-Nav version 1.19 (Gann, 1992).
