4.2File Menu

4.2.1New Project

To process multiple baselines for the first time, start a new project. To do this, use File | New Project.

GrafNav Batch’s project configuration files carry a BNV extension.

4.2.2Open Project

To open an existing project, follow the steps in the shaded box.

4.2.3Save Project

The program automatically saves the project file (BNV) prior to processing. Any changes made to the observations are also saved.

4.2.4Save As

Use the Save As command under the File menu to create a new project that has identical processing options as the current project. This allows you to change the options in the new project and process the data without losing the solution computed by the original configuration.

4.2.5Print

See Section 2.3.5, on Page 35 .

4.2.6Add Baselines

Use this feature to add independent single baselines to the project. Before added single baselines, specify whether this project will contain One base many remotes or One remote many bases.

Under the Source Files window, select which GPB files to add as masters and remotes and click OK. You will be prompted to enter base station coordinates. You will also be prompted for antenna information at all base stations and remote stations. See Section 2.3.6, on Page 36 for additional information regarding antenna measurements.

How to open a project

1.Choose Open Project from the File menu.

2.Choose the name of the project from the dialogue box (BNV file).

3.Click OK.

How to combine baselines

1.Highlight two or more baselines from the

List of Baselines window.

2.Select Process | Combine Selected MultiBase. The window that opens contains settings regarding the combining process.

3.Specify the combined baseline from the pull-down menu.

How to import CFG files

1.Click the Browse button to locate any CFG files to add to the current project. If a multi-base baseline is being imported, you have to following options:

•Enable the Break MB projects up into separate baselines option to create an individual baseline for each base station in the project.

•Enable the Keep MB baseline in project to add the multi-base baseline as-is to the project.

•Use the Skip disabled base stations option in conjunction with the first option to determine whether or not disabled bases in an imported multibase baseline will be used when creating individual baselines.

4.2.7Add Multi-Base Baselines

This option adds multi-base baselines, where the observations from all the stations will be processed in the Kalman filter. The best time to apply this feature is after single base baselines are added because it prevents you from having to enter base coordinates twice. See Section 4.2.7, on Page 182 to add multi - base baselines.

4.2.8Add Combined Baselines

This option adds a combined baseline to the list of baselines in order to combine more than one pair of baselines in one project. Combined files as well as multi-base baselines can be combined. The steps to do this are in the shaded box.

4.2.9Import CFG Files

This feature allows you to import baselines, as well as their solutions, from other projects. The steps are in the shaded box.

4.2.10Edit Selected Baseline Settings

This option gives you the ability to edit the base station information, as well as antenna information at the base and remote. If more multiple baselines are selected, then any shared information can be changed. See

Section 2.3.6, on Page 36 for information on the Base Station and Remote Antenna tabs. See Page 62 for information concerning the Initialization tab.

Only the Solution and Combine tabs will be discussed here because they are unique to GrafNav Batch.

Solution

Solution to Load

This setting selects which solution to use after processing. Automatic is the default, but select the forward or reverse solution if one is deemed most optimal. To do this, right-clicking on the baseline, and selecting Solution Usage. See Section 2.5.3, on Page 91 for a description of the options available with the

Combine Settings button.
