Abstract: The commonly used positioning navigation device is split beacon for surveyors during marine geological survey. The split beacon is composed of antenna head, cable, main unit, date line, computer and generator. But the cable which connecting the antenna head and main unit is often damaged by sea water corrosion in practical work, besides, these accessories have to be moved, the process of operation is tedious, and unsafe especially in stormy wave. After the research it is found that there is no Host-Antenna integrated beacon machine in domestic, so released the integrated beacon that need not to set up base station, transmit differential signal by beacon, and also can be used in far offshore water through satellite station differential service to support the location information. The test results show that it meets the requirements of engineering accuracy and improves the efficiency and safety of maritime positioning.

Key words: RTK, beacon differential positioning, satellite station difference, static observation, carrier phase observation
