Configuring a Scenario
Prior to configuring a scenario, you have to select it: In the Main Menu, highlight Select, scroll through the list of scenarios, and press enter (for more information, see "Select" Menu).
For a list of scenarios pre-installed on a GSG 6, see Pre-Installed Scenarios (the scenarios pre-installed on your unit may be different, depending on your GSG model.)
Once a scenario has been selected, a number of Views will guide you through the list of parameters configurable with the chosen scenario.
Note: For a list of all configurable scenario parameters, see "Select" Menu.
In the first Scenario Configuration View, basic information like position, date and simulation duration are provided:
Scenario Configuration View 1/3
To navigate between fields, first press the UP/DOWN arrow keys to select the field label. Then press enter or the RIGHT arrow key, to begin editing the values. To move to the next field on the same line, press enter, or the RIGHT arrow key. To move to the previous field on the same line, press the LEFT arrow key.
To proceed to the next View, press view.
To finish editing, press start, exit, or cancel. (With start and exit, you will be given the choice to save the scenario under a different name.)
The second Scenario Configuration View allows you to configure the Trajectory, Ephemeris data, Event data and Leap Second simulation (LS).
Also accessible from this View are:
- The Antenna submenu, which allows the configuration of the Antenna model, Lever arm, and Elevation mask.
-
The Advanced submenu, which provides access to Multipath and Interference signals. Also, the Base station (RTK option) can be turned on, and output messages defined. Environment models can be changed to ‘set’ which allows the selection of Environment and Vehicle models (created with the third-party tool SketchUp (a Technical Note about Vehicle Modeling using Sketchup is available upon request).
-
The Atmospheric model submenu.
Note: Some of the functionality shown is optional. For more information on GSG Options, see GSG Series Model Variants and Options.
Scenario Configuration View 2/3
The third Scenario Configuration View allows you to configure the satellites to be simulated.
Note: Some of the functionality shown is optional and may be grayed out. For more information on GSG Options, see GSG Series Model Variants and Options.
For each satellite constellation your GSG unit can simulate (e.g., GPS), you can:
- In the Satellites View (see illustration below), set the maximum number of satellites to be simulated (using the UP/DOWN arrow keys). Or, use the Auto setting, which lets the GSG simulator automatically select the highest number of satellites available for the number of channels supported by your GSG unit.
In the Satellites View, you can also configure the number of SBAS satellites (see SBAS Satellites).
- In the Signal Type View, select the signal types to be simulated for the highlighted constellation (e.g., "L1CA"), and enable (pseudo-P(Y)) encryption (if available).
Scenario Configuration View 3/3
- In the Signal Type View, press the view key to access the Constellation View, which allows you to specify the Blocks (or the "vintage") of satellites simulated. For more information about this subject, see Default Scenario Satellites.
The Default setting in the first row of Constellation View, GPS Constellation (or GLONASS Constellation, respectively) will simulate the satellite constellations as they existed on April 22nd, 2015.
