the session menu can be used to navigate to other Session Web Pages. Other controls for this web page
appear on the left side of the map.
1.4.4.1 Help, Back and Refresh
Help,
Back, and
Refresh buttons at the top of the controls. The
Help button is under development and
may ultimately provide the same resource as this document. The
Back button “moves back” to the
previous web page in the browser’s history. Its action is identical to the browser’s back control. The
Refresh button forces the project to be scanned and the session web page to be reloaded.
1.4.4.2 Manager’s Page
If the project manager has accessed from the project manager’s web page, the Manager’s Page button
appears providing a convenient, direct link back to the project manager’s web page.
1.4.4.3 Show File
The
Show File button reveals a pop-up window for displaying solution reports. Across the top of the
window are controls (Figure 1.49). Standard pop-up window controls appear
at the top, but instead of a
single button at the top-center to initiate an action, this window offer a choice of available reports:
OPUS, session processing, or network adjustments. Below the controls is a header providing the
report’s name, its creation and download (current) times. Then the report is displayed.
Some browsers offer a print option by right-clicking (right mouse button) anywhere in the report. All
browsers should allow the report’s text to be copied and pasted into another file using the method
typical of the operating system. See
Appendix B for more information.

1.4.4.4 Send Email
Send Email (Figure 1.50) displays a pop-up window with basic controls permitting the project member
viewing this page to send emails to members of the project team, including herself or himself, or the
OPUS Projects team. Pop-up window controls appear across the top. Below these controls, the email’s
recipients can be selected and subject added. The emails can include available reports as attachments.
These can be selected by using the next controls. Finally, there is an entry field for a short text message.
"Field Members" are the email addresses supplied with the OPUS uploads so there will always be email
addresses under the "All Field Members" selection.

As always, pop-up window controls appear across the top (Figure 1.51).
Note that the
Solution Name box offers a way to identify the processing results. The initial automated
default is the program assigned
session letter which, in the example shown in figure 1.51, is ‘B’. A
custom name may be used, but it is recommended that the session letter be used as part of that name
for traceability. If processing has already been completed for this session, the session name used in that
processing will become the default. This allows you to reprocess a particular session, change the name
it
is saved to, and then compare the session solution results.
Next, the
Solution Span is given. The
Solution Span is based solely upon the project mark GNSS data
files in this session (CORS data files are always assumed to contain “full days” so including them in
calculating the time span would mask meaningful information). The processing span cannot be edited
and is provided as a convenience.
Below the
Solution Span, are lists of the project marks and CORS included in this session with controls
for each. The controls, from left to right are:
A checkbox that, when checked, indicates that this project mark’s data file is to be used in the
processing. If a project mark is omitted from the processing by unchecking this box, the other
controls for this mark are disabled (greyed out) to help indicate this condition and avoid
confusion.
A checkbox ("HUB") indicates the option that the project mark is to be used as a “hub” in
network design. The significance of hub marks
is discussed in Sections
1.3.5.2.4.8
and
3.4, but, in short, hubs are preferentially selected for forming baselines (a network radial design
with a single hub mark can look like the spokes on a wheel with the hub mark as the hub of the
wheel), and give some control over the automated network design.
The constraint pull-down menu specifies if the project mark’s coordinates are
to be constrained
(their adjustment limited in the solution). The available choices are:
NONE
- no constraint is to be applied.
3-D
- the horizontal and vertical coordinates are to be constrained.
HOR-ONLY
- the horizontal coordinates are to be constrained.
VER-ONLY
- only the vertical coordinate is to be constrained.
WARNING: Although possible to do it is recommended the user not seed alternate heights or latitude,
longitude coordinates for session processing. That should be left for the final series of network
adjustments only.
A pull-down menu designating that the ellipsoid (EL HGT) or orthometric height (indicated by
the name of the geoid model used to relate the orthometric to ellipsoid heights) is found in the
next box to the right. If a project mark is not selected to be constrained vertically, this menu will
be disabled.
The ellipsoid or orthometric height,
in meters, depending upon the selection in the menu to the
immediate left. This is an input field and the value can be changed, but doing so may/will make
the solution results inconsistent with the National Spatial Reference System. If the project mark
is not to be constrained vertically, this input field will be disabled.
The latitude and longitude in degrees, minutes and seconds. These are input fields and their
values can be changed, but doing so may/will make the solution results inconsistent with the
National Spatial Reference System. If the project mark is not selected to be constrained
horizontally, these input fields will be disabled.
The Reference Frame and Epoch is pull-down menu giving the reference frame and epoch of the
height, latitude and longitude. If the project mark is not selected to be constrained, this menu
will be disabled.
