Four Parameter Set:

Four-Parameter is used to transfer the different Coordinate System. It can be calculated through

two known points and the original coordinates of them in the Control Point Library. The four

parameters are X translate, Y translate, circumrotate angle and scale. You can also calculate the

four parameters by using correction wizard to adjust at least two known points. The four

parameter calculates by these two means are the same.

The calculation of Four Parameter refers to: Tool Calculate Parameter Calculate Four Seven

Parameter Set

Seven Parameter is the Closure Parameter between two ellipsoids, it includes three translate

parameter, three rotating parameter and one scale gene. It needs three known points and their

geoids coordinates to calculate.

The detailed steps are: ToolCalculate ParameterCalculate Seven.

Alt Closure Parameter Set

The parameter includes six parameters, in the control point library mode, you need three or

more than three known points and their original coordinates to calculate the closure parameter

to do plane closure, and you need six or more than six points with their original coordinates to

calculate the closure parameter to do arc surface closure.

Adjustment Parameter

When you use the control point library, if you only type in one known point and its original

coordinate, the parameter you acquired is the adjustment parameter. You can also obtain the

adjustment parameter by use of one known point to adjust. The result obtained by these two

methods is the same.

4.2 Control Point Library

The control point library is used to calculate the adjustment parameter. It is very convenient to

edit and view the adjusting point, and to examine the accuracy after adjustment. Here is the

detailed process: We use the two known points, Point A and Point B, to calculate the

adjustment parameter, firstly we must note down the original coordinate of these two points,

which are obtained by the rover in the fixed state without any adjustment parameter. Input the

known coordinate of Point A in the control point library, and then enter the original coordinate

of Point A according to the prompt. The adjustment parameter will be calculated (*.cot) after

entering the known coordinate and original coordinate of Point B.

Open the Control Point Library (see Figure 4-10), the Add, Delete and Edit buttons are

the relevant operation to the known coordinates and original coordinates of adjusting point. The

button on/off is the option of plane calculation or alt calculation. Open button is to fold the

coordinates in point library, Save button is to save a adjustment coordinates document *.cot.

Click to input the coordinates of the first known point (see Figure 4-11), you can also

fold the coordinates from the coordinates management library (see Figure 4-12). The software

will guide you to input the original coordinates of the relevant point (see Figure 4-13).

Chapter IV Set


There are four paths to input the original coordinates (see Figure 4-13): First, add the

coordinates from coordinates library (see Figure 4-14), Second, Read the coordinates of the

current point (to note an original coordinates when doing leveling and save it in the dialog),

Third, Read the coordinates of base station (to read the original coordinates when the basestation is on the known point), Fourth, Input the geography coordinates. We recommend the

first path.

Note: In general, plate transform needs at least two points, and the alt transform needs at least

three points. If one level point has no plate coordinates, you need to collect this point first and

change the alt to the known alt when folding the region coordinates of this point. Before saving

the file, youd better check whether the plate accuracy and alt accuracy meet the requirement.

in typing coordinates of adjustment point or in the process of adjustment, or there is a need to

readjust the coordinates of the measurement point. You can use this function and control point

library to regain the adjustment parameter and to process the measurement point in batch,

which may avoid the repeated work in field surveying.The detailed steps: open the data process menu (see Figure 4-17), select the original data file

*.rtk (Figure 4-18), then select the correct transform parameter file *.cot Figure 4-19 then

save the file after finish the data process Figure 4-20 .

Note: If you adjust with one point, you need to input the original coordinates of the point in

the control point library. If you use two or more than two points to adjust, you need to input

the relevant coordinates of these points. You need at least three points with their original

coordinates to do the alt closure.

Process: SetRover Set

Note: Set the format of receiving data of rover, click downwards button to select the consistent

data format with the base station.

The level of the accuracy of calculation can be shifted between high and common, this

subject to the surveying surroundings and the requirement of the surveying accuracy. In usual,

we select high level, whereas, we can also select the common level in case that the work

environment, such as the forest or bush is not so strong, is not so fine and the requirement for

the surveying accuracy is not so high. Thus the fixed speed will be faster.

There are four types of Points Save:

General Save: Directly save the coordinate of point digit at certain time. (The coordinate of

point digit is updated per second)

Smooth Save: Obtain the average value after times of measurement of each point.

Auto Save: Save the point automatically according to the pre-setting term. (Save by time or by

distance).

Excursion Save: Supposed we now measure Point A, but it is impossible or inconvenient to do

for some reasons such as in the house or under the veil. In this occasion, we may use this

function. Firstly, we measure Point B that is measurable, then we obtain the azimuth, the

distance and the vertical difference between Point A and Point B. Thus we can obtain thecoordinate of Point A through Excursion Save. Select Excursion Save in the Set Save Type

menu, click the button-- or , you will see the screen to input excursion value.

Figure 4-24 Excursion Save

4.5.2 Satellite Limit

For the refraction, which arises in the process of the satellite signal of low height angle

penetrating the Flayer and troposphere, is great and the multi-way effect. The signal of the low

height angle generates diffracting effect when being received. We have to select the appropriate

satellites, Engineering Star Software provide this function to meet this demand by masking the

satellite of low height angle. See Figure 4-25 that shows the tag to input 10oas the mask angle,

thus the satellite below 10owill be screened from adopted.

real elevation will be display on the surveying screen. If you dont click the toggle, the screen

will display the elevation of the antenna phase center. After you set the Antenna Height, you do

not need change the value during surveying when the antenna height does not have a change.

4.6 Receiver Set

Figure 4-27 Receiver Set

Process: SetReceiver Set

Note: There is Kinematic State and Static State to select, the former has the base set, and the

latter carries out static collection function.

You can use notebook to reset the base of RTK by using single point orientation or manual

inputting coordinate. Base parameter, such as the difference format and interval amend, can be

revised synchronously.

When you use static function, you can adopt the Static State in the Receiver Set Menu to set the

Static Collection Parameter, such as the file name, antenna height, collection interval and the

parameter of mask angle to do the dual frequency static collection.

4.6.1 Kinematic State

Process: Enter Receiver Set, you will see the screen as Figure 4-28, select the Kinematic State,

click OK to enter the next step.


37/140

Chapter IV Set


Figure 4-28 Kinematic State

You can use two ways, which are single point orientation coordinate and manual inputting

coordinate, to set the base station. The single point orientation coordinate is the usual way,

which is much like the RTK with automatic base station set, such as the mainframe of 9800.

The manual set function is usually used in the following situation: (1) The standard coordinate

of the datum point is known. (2)The transferred coordinate is known. (3) Transferring

Parameter is known, such as base station reset. Do not set the unknown coordinate as the base

station when you do now know the coordinate of known points. This will make the base station

not work as usual, neither do the projecting difference.

1. Single Point Orientation Coordinate

Click the tag Auto run the base parameter set, enter the next step.

This function can make the instrument automatically collect the single point orientation

coordinate and set this coordinate as base station. We also need to set such parameters as

projection interval, difference data format, Satellite Mask Angel and PDOP, etc, to improve the

satellite condition for the base station start. The base station can only enter the normal

projection difference program after you finish all the parameters set, click OK to end this

step.

If you see the message Auto set finished, it means the set is finished. In usual case, check

whether the radio works according to the set projection interval, then use the PDA with the

rover station.

2. Manual Inputting Coordinate

Select Set the base station by inputting coordinates to enter next step.

In this interface, you can input the base station coordinate by two means: inputting with

geography coordinates and inputting with plane coordinates. Swift the inputting way according

to the instruction on top of the screen Note: The message Reset the station next time? in the bottom of the screen only work on

Chapter IV Set


Smart S80. It is used to set the projection means of base station, thus you can continue the

former set when you switch on the station without the PDA. This is convenient to the base

station operation, but if you move the station or change the antenna height, you need to modify

the parameter by using PDA. Generally, you are not recommended to click this toggle, pleaseoperate according to the instruction.

4.6.2 Static State

Steps: Enter Instrument Set, select Static State, click OK to enter the next step (see figure

4-29).

Figure 4-29 Static State

Figure 4-30Static Collection Set

Static State is one function of the RTK instrument (see figure 4-30). You can set the static

collection parameter such as File Name, Antenna Height, Collection Interval and Mask Angle

etc. Click OK to finish this step; you can only type 4 characters or numbers in the name field.

The unit for antenna height is meter, second to collection interval and degree to mask

The collected data is saved in mainframe; you can use South Receiver Data Download

software to connect the receiver for transferring and transaction after.Note: South Receiver Data Download is in the GPS data transaction software, you can go to

http://www.southsurvey.comto download.

4.7 Radio Set

Note: This function is only designed for Smart S80.

Process: SetRadio Set, see Figure 4-31

Note: You can read the data or switch the radio channel from RTK. The operation to base

station reacts on the outside radio, and the operation to the rover reacts on the inside radio.

Select Switch to reset the designed channel, you will see the message switch the channel.

Select Auto Research to enter the Auto Rover Set state, in which the receiver can auto setthe rover state, thus the buzzer will call to indicate channel switch in case the main frame loses

the signal during the work.

When you finish the channel set, the interface will display the channel number in front of the

signal state of antenna.

Note: The range of channel i s from one to four, if the number of base station i s over f our in

cer tain region, you need to set the frequency point to the channel to ensure that all the base

station work normal ly.

5.1.1 Save Set Type

There are four types of Points Save:

General Save: Directly save the coordinate of point digit at certain time. (The coordinate of

point digit is updated per second)

Smooth Save: Obtain the average value after times of measurement of each point.

Auto Save: Save the point automatically according to the pre-setting term. (Save by time or by

distance).

Excursion Save: Supposed we now measure Point A, but it is impossible or inconvenient to do

for some reasons such as in the house or under the veil. In this occasion, we may use this

function. Firstly, we measure Point B that is measurable, then we obtain the azimuth, the

distance and the vertical difference between Point A and Point B. Thus we can obtain the

coordinate of Point A through Excursion Save. Select Excursion Save in the Save Set Type,

click the button-- or , you will see the screen to input excursion value.

6.1 Calculate ParameterSteps: Tool Calculate Parameter

InstructionThis function includes Calculate Four and Calculate Seven, the operation is similar,

but the meaning is different.

6.1.1 Calculate Four Parameter

This function needs two or more than two points region coordinates, acquire the source

coordinates and input it with the region coordinates, when the points are sufficient, you can

start the calculation and acquire the plane translate coordinates transformed from regioncoordinates used by GPS, which are X translate, y translate, circumrotate a and zoom k.

Steps: Enter calculate four parameter, and click Add button to input coordinates in turn, click

OK to save it, see Figure 6-3 click Calculate to generate translate parameter.

6.1.2 Calculate Seven Parameter

If the survey area is large (more than 50Km), you can use Seven Parameter to acquire more

accurate Seven parameter translate coordinates. It needs three known points region coordinates

and their WGS-84 coordinates to calculate seven parameters, which are the seven translate

parameter of the region coordinates transformed from WGS-84 coordinates. Click OK to type

in the dialog of seven parameters.

Note: Youd better make the area of three points cover the whole survey area to acquirepreferable effect.

Figure 6-6 Three known points and survey area map

The format of seven parameter: X translate, Y translateZ translateX axis rotate, Y axis rotate,

Z axis rotate, Zoom scale (Scale Ratio).

Principle: As you know, the RTK survey used with translate parameter can make the plane

coordinates of survey point, height accuracy and control net cooperate very well in small area

(such as tens of sqkm) and you only need two or more than two region coordinates. But when

you do the survey in a large area (such as hundreds of sqkm), the translate parameter cannot

improve the accuracy of plane and height within parts of area. Thus you need to use seven

Note: The concept of three parameter is generated from seven parameter, if do not calculate all

axis rotate and scale for seven parameter, you only need translate parameter which is mostly

used in the small area and low-rise area.
