Procedures for the use of Marine navigators

With the rapid development of the Marine industry, the number of ships increases, the tonnage increases, the sea traffic becomes increasingly crowded and busy, so it is required that Marine instruments can quickly provide more accurate directions, more accurate positioning accuracy and a variety of USES of navigation data. The birth of Marine navigator greatly facilitates the navigation workers, especially when it is difficult to distinguish the direction at sea, the Marine navigator can give the correct direction to the ship operator. In addition, for some new places, the Marine navigator can also provide the ship operator with a correct and reasonable route. Below is small make up to introduce the use of Marine navigator steps.

Connect the host computer and computer with special cable, connect the GPS power supply, and turn on the computer. 1. Establishment of the project: first of all, it is to run the main program of the free software. Then create a new project, including the main input project name, determine; Input basic information; Set the projection parameters, select the coordinate system, and input the middle meridian; Instrument setting: select S35 difference extension for GPS model and set the communication port; Data acquisition Settings, GPS data acquisition conditions select difference decomposition

2. Planning line design: make planning line or measuring area. Method 1: operate under the design menu. Can use automatic wiring model, channel wiring, area wiring, linear parallel wiring, compound line flat wiring, vertical wiring, fan wiring, etc. This method is often used in simple engineering. Method 2: import the projects-> graphics. Before construction, convert the construction plan drawn by AutoCAD into R12/TL12 or DXF format and input it into the computer.

3. Verification: position the GPS host computer at a known point near the test area, click the shortcut button to connect the instrument to the GPS host computer, click the calibration wizard under the setting menu, input the known point coordinates, and conduct verification. The purpose of checking is to find out the correction parameter, which has different values in different test areas, so an operation should be carried out in different test areas. The specific steps of the school is: in the construction of the left and right sides of the slope and then use the GPS measurement system (cm level) to check, to prevent the lack of excavation leakage excavation, and put an end to the excavation, effectively improve the quality of construction; Open the operation method of the project; Run the free software main program; Open the previous new project; Open the setting dialog box and set the GPS connection port; Click the shortcut button to connect the instrument and connect the GPS host computer; Click start measurement, start recording data and save; Click stop measurement, stop measurement; Click the exit button to exit the main program
