南方RTK测量如何求七参数？(国外英文资料)Normally maximum distance less than 10 kilometers of area, it is ok to use four parameters, many papers have proved the conclusion for a small range of measurement area, using four parameters of coordinate transformation results better than seven parameters of coordinate transformation.1. The parameters of the process of solving basic same, is set up at the center of the surveyed area base station, and then use the rover new construction, set up the basic projection parameters, such as xian coordinate system 80, gauss projection, central meridian, Y constant 500 km, etc.,Direct use of the flow station to three or more known high level control points to measure the coordinates of the fixed solution state.The solution parameters: enter the result coordinates of the known control points in turn, and specify the coordinates of the corresponding control points for the previous RTK measurements, and then apply them after saving the parameters.Check: use the RTK mobile station after the application parameter, measure a known control point, and check the difference between the observed coordinates and the coordinates of the observed coordinates.Southern spirit S82RTK operation step and use technique sharingThe first distributor: gao yhui has been Shared with one review (0) to share and share reportsOne. The base station section1) base station installation1. The benchmark stand erect points on feet, installed base, then connect the benchmark station host by head placed on a pedestal, of the leveling (such as in unknown point, is roughly the leveling).Note: the base station erection points can be worn on known or unknown points, both of which can be used, but the steps differ when adjusting parameters.Placed 2. The transmitting antenna and radio, connect the antenna with head in the other foot rack, the side of the station on foot frame, with the launch on the radio antenna cable, with a power supply cable will host, radio and battery connected and pay a
