How to use Jiaming Positioner

(1) GPS correction

There is no mainland coordinate system in Jiaming GPS. The default of the machine is the WGS84 coordinate system, which needs to be corrected to the coordinate system that matches the topographic map.The specific operation steps are as follows:

1. First set the parameters inside the GPS receiver to "0", that is, DX = 0, DY = 0, DZ = 0, DA = 0, DF = 0, where DX, DY, DZ are the same two coordinates of the same point.The system three -dimensional coordinates value, DA is the two -coordinate system long -axis difference, DF is the difference between the flat rate of the two coordinate systems.

2. Use the GPS receiver to observe the coordinates of the known triangle point, and find their respective differences according to the observation results and the known coordinate values, and take their average value as a correct value of DX, DY, and DZ.

3. The parameters of the receiver DX, DY, and DZ that have been observed are set to the number of corrections that have been obtained, and DA and DF are set to the corresponding difference, that is,

A (84) a (84) -a (54) = DA = -10

(8484) - (5454) = DF = 0.0000005, A (84) A (84)-A (80) = -3 (8484) - (8080) = 0.00000003

4. Observe the known points coordinates on the same triangle point, and add the second new correction to DX, DY, DZ according to the observation results.At this time, use the GPS positioning instrument to observe all the coordinates of all known points for the third correction until the coordinate value of the observation of the GPS receiver is close to the known point coordinates.The average value of the observation value of the point and the known coordinates is the final correction number of DX, DY, and DZ. The above operations generally circulate to the second time to get the ideal correction number.

(3) No picture use

1. Use road fixed points

It is often used to determine the coordinates of the cave coordinates or other line starting points, turning, and Camping points when determining the coordinates of rock walls or caves.Simple usage, Mark's coordinates are enough.

2. Use route input route

If you can find the route information recorded by a friend you have visited before, enter the GPS to form a line, or (common to return to the original road) to edit the road signs recorded in the previous record into a line.
