The Occupation tab displays the following information: the point’s name, mode, observation

period, antenna height and type, navigational coordinates and deviations.

The Deviation column is shown for checking points that have the same name but referred

to different locations. For a point that was occupied only once (and therefore no check data

for its position is available), the zero deviation is shown. If a point was occupied more than

one time, the deviations between navigation positions for its occupations are given,

referred to the occupation position that has minimal RMS value (for this reference position,

zero deviation is assigned).

• The graphical view of point occupation and sessions is given in the Occupation Graph tab.

Processing Static Observations

The JavadGeo Engine Main Features

4.3. Processing Static Observations

After the measurement data has been imported and splitted into sessions, you are ready to start

processing. In Giodis the JavadGeo engine makes static observation processing. “The JavadGeo

Engine Main Features” on page 51 describes main features of the JavadGeo engine. “Running the

JavadGeo Engine” on page 52 learns you how to run the engine and keep track of preliminary

results.

4.3.1. The JavadGeo Engine Main Features

The main features of the JavadGeo engine are the follows:

• Multi-baseline (session) processing, that allows accounting for correlations between

simultaneously observed vectors and removing the problem of trivial vectors. If a session

includes two-points observation, the engine fulfills traditional baseline processing.

• Un-differenced (zero-differenced) phase and code data are processed.

• Lambda method of phase ambiguity resolution is used.

• The meteodata library is used for a priori troposphere delay calculating. The library contains

the global spread meteodata. Meteodata for a surveyed point is interpolated based on the point

geographical location and height, as well as the observation date and time.

• Direct impact and behavior of ionosphere and troposhere, satellite and receiver clocks on

GNSS observations are estimated.

• Orbit relaxation parameters are determined.

• The IGS/CORS reference points data and the user collected observation data are processed

jointly. This allows better estimating satellite clocks and orbit relaxation parameters thus

improving the accuracy of surveyed points. This, in turn, enables to better determine long

baselines even without precise ephemeris.

• The effects of solid Earth tide on point positions are accounted for.

• The result of the JavadGeo engine is:

• a multi-vector subnet, if the IGS/CORS reference points data is not used for

processing or

• a multi-points subnet, if the IGS/CORS reference points data is used for

processing.

4.3.2. Running the JavadGeo Engine

To run the JavadGeo Engine, perform the following steps:

1. Create a project or open an existing project. (See Chapter 3 on page 27).

2. Import measurement data files (See “Importing Data Files” on page 39).

Note: While importing data files, measurements data is splitted into sessions. The generated sessions

are represented in the Map window and in the Occupation Graph tab.

3. If you are working with IGS or CORS reference points, include the IGS/CORS point

positions into the project. For this use the following options:

• manually specify a point as ECEF control (See “Setting ECEF Control” on page 54).

Note: If the point has been specified as ECEF Control, it changes from to in the Points tab and on the

Map.

• enable control data contained in Control Points Catalog. Go to the Catalog tab, find the

needed control point, mark one or several check boxes in the Selected column.

Note: If the control point has been selected in Control Points Catalog and included to the project, it changes

to in the Catalog tab and on the Map.

4. Click Project Process Sessions (Figure 4-16).

It opens the JavadGeo Engine dialog window displaying the processing progress bar and

summary (Figure 4-17 on page 53). Sessions of the project are processed one after another

without stopping. When all sessions of the project have been processed, the JavadGeo

Engine dialog window closes.

Note: If you want to see the results after finishing each session processing, clear the Continuous

processing check box in the Configuration dialog window, the Processing tab. In this case you

must click OK (Figure 4-17 on page 53) to begin processing of the next session.

• The point image changes from to on the Map.

• The Subnets tab appears underneath the Map showing the following information: subnet

number, subnet type, points included in the subnet, point’s coordinates, and RMS errors.

Subnet type displays Vectors or Absolute. Subnet is designated as “Vectors”, if the IGS/

CORS reference points data is not used. Subnet is designated as “Absolute”, if the IGS/

CORS reference points data is used.

Note: In the Subnets tab the first point of the list is Initial Point. This point is designated as Initial Point

by the program and its coordinates are not assigned accuracy estimate, as you can see it in the

corresponding RMS columns of the table.

Note: In the Subnets tab, if the subnet type is Absolute, IGS/CORS points coordinates are considered to

be precise. So their coordinates are not assigned accuracy estimate, as you can see it in the

corresponding RMS columns of the table.

Performing Network Adjustment

The Order of Adjustment

4.4. Performing Network Adjustment

The adjustment has two main goals:

• Detecting blunders in adjusted data.

• Calculating the most reliable and accurate results (in our case -final local coordinates of

surveyed points and their realistic error estimates).

The network adjustment can be performed in two steps:

1. The minimally constrained network adjustment (or, free adjustment) is performed in

which only one station is held fixed. This allows to detect possible blunders in adjusted

GNSS data (e.g., missed antenna heights), and in control positions (say, misprint errors in

control data catalogs). For this, different statistical tests are applied like global (Chi

square) test or Tau test.

2. If there are no blunders in the adjusted data, the second step can be done - the fully

constrained adjustment in which all the known (published) coordinates of control points

(horizontal and/or vertical) are held fixed. This allows to fit the GNSS network into the

local control.

4.4.1. The Order of Adjustment

1. All the processed subnets are assembled into a common network. The integrity of the network

is checked; it should not have any breaks.

2. The system of equations for the minimally constrained adjustment is formed. Depending

on the approach that was chosen to processing, the following types of subnets can be

adjusted:

• Single baseline solutions, i.e., vectors and associated 3x3 covariance matrices.

• Session processing solutions, i.e., a set of non-trivial vectors and the covariances between

them.

• In case if field GNSS observations have been processed along with data from IGS/CORS

reference stations, the adjusted subnet consists of absolute ECEF coordinates and the

covariance matrix of the subnet.

All these types of processing subnets can be adjusted together.

3. Minimally constrained 3D adjustment of the GNSS subnets is performed; its results are

analyzed based on the Tau and Chi square (VPV) statistical tests. Tau test allows to detect

and reject blunders in adjusted observations. VPV, or global test, is used to check whether

the observation error estimates made by the processing engine, are close to the expected. If

this is so, the standard error of unit weight output by adjustment, is close to 1.

www.javad.com

55


Working with Project

Performing Network Adjustment

The Order of Adjustment

4. After finishing the minimally constrained adjustment a fully constrained adjustment is

run. The constraints are horizontal and/or vertical coordinates of local control points.

The Giodis software allows three types of constrained adjustment:

• Horizontal adjustment in which only horizontal control coordinates (geodetic or grid) are

known. In this case the output results are adjusted horizontal positions of GNSS network.

• Vertical adjustment in which only elevations are used as control data. In this case the main

goal is to calculate point elevations referred to a local vertical datum.

• Three dimensional adjustment with both horizontal and vertical control. In this case,

horizontal coordinates and heights of surveyed points are adjusted.

5. Because GNSS subnets and local control refer to different datums, the constrained

adjustment procedure estimates the datum transformation parameters. Depending on the

type of constrained adjustment, Giodis estimates the following sets of transformation

parameters:

• Horizontal transformation parameters - a shift (two parameters), azimuth rotation angle

and scale - that describe the differences between horizontal positions given in global (e.g.,

WGS84) and local datum.

Note: If the subnets not referred to ITRF are adjusted (i.e., the subnets were not tied to CORS/IGS

stations), only rotation angle and scale parameters are estimated.

• Three parameters - the values for a slope (two parameters) and vertical shift - that describe

the difference between heights referred to global WGS84 ellipsoid and to local vertical

datum.

Note: If the adjusted subnets were not tied to CORS/IGS stations, only slope parameters are estimated.

• Seven parameters for both horizontal (four above mentioned parameters) and vertical

(three above mentioned parameters) transformation.

Note: If the adjusted subnets were not tied to CORS/IGS stations, only four parameters are estimated -

three rotation angles and scale.

Checking the quality of control positions.

To check the quality of your local control, perform the following steps:

1. Perform minimally constrained (free) adjustment of the GPS network.

2. After the free adjustment is successfully finished (i.e., all blunder vectors have been

detected and removed from the network), do the constrained adjustment with minimal

control. At this step, constrain the adjustment solution by only one horizontal control

position (in case of horizontal adjustment) or by one fixed height (when you are interested

in adjusting vertical positions), or by both horizontal and vertical coordinates when doing

56 www.javad.com


Working with Project

Performing Network Adjustment

Running the JavadGeo Network Adjustment

three dimensional adjustment. Note that in the latter case you may use fixed horizontal

coordinates and height that refer to different control points.

3. In this adjustment, for all points of your network (including control points) the local

coordinates are calculated. Compare the calculated coordinates of the control points (other

than the point that was used as fixed) with their published (true) values. If the differences

are more than expected the corresponding coordinates may be incorrect. Check the suspect

coordinates; at worst, do not use the corresponding control point positions in the final

adjustment. It also may be so that the calculated position differences for all points are big

but very close to each other. This may indicate that an error occurs in the position of the

point that was chosen as fixed. In this case, select another control point and try Step 3

again.

4. After all your control coordinates have been successfully checked, do the final step, i.e.,

perform the fully constrained adjustment.

4.4.2. Running the JavadGeo Network Adjustment

To run the JavadGeo Network Adjustment, perform the following steps:

1. Process the sessions and get the subnets, as described in “Running the JavadGeo Engine”

Step 3. Studying the Data Loading Results

1. In the Map window, you can see the following (Figure A-6):

• the points depicted as , where observations were made

• measurement data splitted into two sessions and named Subnet #1 and Subnet #2.

• the error ellipse of the average navigation position for each point, the scale for an error

ellipse shown in the lower left corner of the map.

2. To view information on each occupation, click the Occupations tab (Figure A-7).

• The Occupation tab displays the following information: the point’s name, the occupation

mode (enable, disable), observation period, antenna height and type, navigational

coordinates and deviations.

• The Mode column is editable. Check that all points in this example have the Enable mode.

It means that all occupations will be accepted for further processing.

• The Deviation column is shown for checking points that have the same name but referred

to different locations. For a point that was occupied only once (and therefore no check data

for its position is available), the zero deviation is shown. If a point was occupied more than

one time, the deviations between navigation positions for its occupations are given,
