dynamic measurement Like the genera

dynamic measurement Like the general quasi dynamic measurement, this measurement mode usually requires the receiver of the mobile station to observe at a certain starting point before the observation work begins, so that the initialization work can be carried out in real time by the method of fast solution of the unknown number of the whole week. After initialization, the mobile receiver needs only a few calendar elements to observe at rest on each observation station, and the 3D coordinates of the mobile station can be calculated in real time with the synchronous observation data of the reference station. At present, the positioning accuracy can reach centimeter. The method requires that the receiver keep continuous tracking of the observed satellite during the observation. Once a lock loss occurs, initialization work needs to be performed again.③ Dynamic observationDynamic measurement mode, generally, it is necessary to observe for several minutes at a certain starting point at a certain starting point, so that after initialization, the moving receiver will automatically observe according to the predetermined sampling interval, and determine the spatial position of sampling point in real time along with the synchronous observation data of the reference station. This measurement mode still requires continuous tracking of observation satellites during observation. Once a lock loss occurs, it needs to be reinitialized. At this time, for the land moving target, it is possible to observe the satellite for several minutes at the observation point where the satellite is unlocked, so as to reinitialize it or reinitialize it by using the dynamic initialization (arof) technology. For the moving targets at sea and in the air, only arof technology should be used to complete the initialization work. At present, the accuracy of its positioning can reach centimeter.
