# Interface Overview and Workflow
# Workflow
The workflow within GIPSIE® is composed of two main steps:
- Open a scenario file and adjust all settings as needed. See Scenario Settings view.
- Start the simulation and create an IF file. See Scenario Simulation view.
- Stream the generated IF file with the IZT S1000. Scenario Streaming.
# Window overview
The main window is composed of three different areas:
- Menu and Toolbar
- The main scenario options and simulation view.
- Status Bar

# Menu Bar and Tool Bar
The Toolbar has three different states:
- Scenario Settings: When a scenario has been loaded and the scenario settings are visible, the scenario can be simulated via the Simulate button.

- Scenario Simulation: When the scenario is simulated, and thus the UI is in the scenario simulation view, the toolbar switches, so that the simulation can be stopped. The map selection is only available when simulation is in progress.

- Scenario Simulation finished: In the scenario simulation view and when the simulation has finished, or the user has stopped the simulation manually, the toolbar switches, to that the scenario settings can be accessed again.

Note
During simulation the scenario cannot be saved.
All options are available via menu bar or tool bar.
# Status Bar
The status bar is visible at the bottom of the window, and used to indicate the current simulation progress and the currently simulated epoch (UTC).
# Scenario Settings
The scenario settings view is divided into two main areas:
- The options selection list, where the different aspects of the simulation environment are listed.
- The options associated with the currently selected options selection list of the left hand view.

# Scenario Simulation
When the simulation has started, the scenario simulation view is shown. This view is structured into different sub-windows:
- The map showing simulated satellites, receivers, jammer and spoofer. The map can be toggled between online and offline map.
- Satellite specific simulated data is shown in this section. Additionally, various simulation settings can be changed during run-time within the Runtime tab.
- The receiver, signal and interferer (jammer and spoofer) simulation data is shown here.

# Scenario Streaming
See the section Scenario Streaming for details.
When GIPSIE® is used in combination with the IZT S1000 (opens new window) system, the generated IF file can be up-converted to RF and streamed. For signal streaming the IZT S1000 GUI is utilized. This GUI is composed of three respective areas:
- Streaming toolbar: Here, i.a. the individual RF hardware outputs can be toggled and the stream can be started/stopped.
- Settings area: Depending on the selected sub-page, different settings for signal streaming can be adjusted in this area.
- Navigation bar: Here, different sub-pages with streaming settings can be accessed.
