Situoli GPS static solution course

1. Before the operation, the technical design should be done, including the starting data, the grade and accuracy of the network, the form of operation network and the embedding of the selected point marker, the accuracy and quantity of the instruments, the main technical requirements, the scheling arrangement, etc
first, set the measurement mode (set to static), sampling interval and satellite cut-off angle of the host before departure. The following is the operation of a single station:
1. Install the instrument& gt; First, center and level the base, and then install the receiving antenna. The steps of installing the instrument: A. place the tripod on the selected observation station. Note that the environment around the observation station must meet the above conditions, that is, good clearance conditions, far away from the reflection source, avoid electromagnetic interference, etc. Therefore, users should try to avoid placing the receiver under the shade of trees or buildings, and do not use walkie talkie, mobile phone and other radio equipment near the receiver. B. Carefully open the instrument box, take out the base and centering device, place it on the tripod, and align and level the base on the measuring point. C. Take out the receiver from the instrument box, place it on the centering device, lock it, take out the collector and its tray respectively, and install them on the tripod& gt; To measure the antenna height, it is generally required to measure three times in three directions respectively, and take the average as the antenna height before measurement. The mutual difference of the three readings is specified, and most specifications require no more than 3mm& gt; Connect the host and antenna with a cable (if it is a receiver integrated with the host and antenna, this step is not required)
2. Power on
3. Fill in the field observation manual. It includes roll call, point number, observer, date, starting time, antenna height, period number, other control points in the same period and so on
4. Observe the receiving status. During the operation of the receiver, it is not necessary to check regularly to see whether the state of the receiver is normal, especially after a few minutes of power on to see whether the data recording indicator is normal. In this process, it is necessary to prevent irrelevant personnel and livestock from walking around the instrument. Any abnormality in the observation process should be recorded in the handbook
5. Power off. When the observation time is up or after receiving the end observation instruction from the group leader, turn off the power supply of the receiver, and then measure the antenna height again. Fill in the manual with the shutdown time and antenna height after measurement
6. Export data: any instrument manufacturer will provide data download software, and operate according to the manual. Before downloading data, a special folder should be set up in the computer to store data. Open Lingrui assistant, connect the computer and instrument, Lingrui assistant software interface will appear, find Lingrui receiver point import acquisition file, in the pop-up interface will display the observation data file in the machine, input the location of data storage in the target directory, select the observation data file to be transmitted (tick before), input the roll call (must be four digits), antenna height, antenna height, antenna height, etc Observation period, and then point to determine. The data of all instruments are transmitted to the computer in turn
2. Data processing new project → open GPS post-processing program of Southern surveying and mapping, file - → new project (input project name, person in charge, coordinate system, control network level), click OK
3. Data input. Data input - → add observation data file, open the saved file of observation data, select all - → OK; Data input - → coordinate data input, select the known spot name, input the corresponding coordinates, and then confirm the point
4. Remove the invalid satellite signal. Click + in front of "observation data file" in the left border to expand all the observation data files. Double click an observation file, click, hold down the left mouse button, and drag to circle the place where the repeated epoch breaks. Then the invalid epoch can be eliminated. Points can be restored to eliminate epoch
5. Baseline processing. Baseline solution → all solutions, so that in the screen display, all qualified baselines are red. Unqualified is grey. If it is not qualified, it needs to be recalculated. Please refer to the manual for specific operation
6. Adjustment. Adjustment processing → automatic processing → network adjustment calculation (after processing, check whether the asynchronous loop and synchronous loop are all qualified. In the baseline profile, check the mean square error of each baseline and the two-dimensional unit weight mean square error in the results, the smaller the value, the better)
7. Results - → adjustment report printout setting (select the content to be printed) and then click OK. Then click Print in the results menu. Print out the adjustment results

the above is in my operation instruction. According to the control range, the site survey is carried out to select the buried points. The connection of the synchronous ring is generally side connected. Before the field departure, the acquisition mode, sampling interval and satellite cut-off angle of each receiver are set according to the technical requirements (do you mean GPS operation), and the remaining operations such as erecting the station and switching on and off the machine are simply repeated, That's the situation in the field. In house processing software may be different, but the processing content and processing order are the same.

2. Select point

3. Static data processing: H66 key state, transmitted by smart assistant; S82 and S86 are transferred by H82 and H86 assistant respectively (the operation is the same as that of Lingrui assistant)
1. Transfer data -- Lingrui assistant transfer -- connect the computer through USB port, open assistant tool, click Import acquisition file -- select the target directory to store (pay attention to modify the transmission path, roll call, time period, Antenna height)
2. Modify the acquisition interval and height cut-off angle - click the instrument settings

4) baseline solution - all solutions - the unqualified baseline is gray, and the qualified baseline is red. Double click the unqualified baseline on the network diagram to pop up the following window, adjust the height cut-off angle and epoch interval higher or lower, and then calculate until the variance ratio is greater than 3

5) output:

4. No, the first step of static solution is to solve the baseline first, otherwise there is no way to carry out the unconstrained adjustment and so on. To put it bluntly, GPS static solution is to calculate the distance between each point, and then translate and rotate to a fixed point, which can be simply considered as geodetic quadrilateral.

5. 1. If you can get two-point coordinates with the total station, why don't you bring the known points into the control network
2. If there are no known points, you have to be like the design institute
3. If it's GPS surveying practice, then use the user-defined two-point coordinates, but the defined two-point coordinates should correspond to the distance of the actual measurement

6. 1. The results of baseline integer solution basically meet the requirements, even most of them are 99.9. Why does the closure error exceed the limit? 2. If it is out of the limit and the baseline integer solution of the closed loop is 99.9, how to adjust it? 3. If I settle accounts directly in this way, will the result be credible? Premise: the three points that constitute the closed loop may have errors caused by the long side and short side. I measured six points with three zhonghaida V8 static machines and made five side connected static measurements. Online urgent, please professionals to answer for me in detail, not very grateful!

7. Example, no, domestic software can solve Tianbao or Leica format files, China Haida's HGO, and hds2003 are very easy to use

8. ① Import observation data; ② Check and modify field input data; ③ The control parameters of baseline solution are set; ④ Baseline solution; ⑤ Baseline quality control; ⑥ The final baseline solution is obtained.

9. Obtain the coordinates of a point, which is the longitude and latitude coordinates in WGS-84 coordinate system. The purpose of static is through multiple G

10. You can make one yourself,
1. Satellite transmits coordinate data of test point (GPS point)
2. GPS transmits coordinate data of (GPS point) to console through GPRS
3. The console calculates the location of each point according to the coordinate data of the electronic map and the coordinate data transmitted by GPS
that's it
