The Impulse System Operations panel provides information on the Astronomical Objects (AOs) in the stellar system the vessel is currently operating in.

1. System Identification

This module identifies the current stellar system, including its reference number, informal designation (if available) and navigation sector.

2. AO Ambient EM

This module displays the ambient EM of the system's Navigable Astronomical Object (NAO) - which is usually the system's star.

The default display can be overridden temporarily by selecting a focus button on the AO list (see below). When a specific focus is selected, the ambient EM of that AO will be displayed instead. 

3. AO List

This module displays a scrollable list of the system's major AOs. It provides the AO's reference number, informal designation (if available), type and class along with a visual representation (which is not to scale).

Position Information

The grid position and radius of each AO is provided.

EM Output

The EM output (at source) of each AO is listed using standard color codes to identify the EM band:

Green: Ionising radiation EM band

Red: Infrared EM band

Violet: Ultraviolet EM band

Blue: Radio EM band

Yellow: Magnetic

Focus

The FOCUS button will highlight the selected AO on the AO Map (see below) and change the focus of the Ambient EM to the selected AO.

4. AO Map

This module provides a simplified representation of AO positions. 

The Y axis is represented horizontally. The X axis is represented vertically.

Colour Codes

The NAO is represented as yellow (and is typically in the centre of the map).

Other AOs are represented as blue, An AO that has been focussed (see above) will be displayed in grey.

The vessel's current position is represented as red.

Scale

The scale of the map is represented at the bottom of the module in Grid Units (GUs).

Map Orientation

By default the X axis is displayed with negative values at the top of the module and positive values at the bottom according to the standard Cartesian model. 

Some operators may find it more intuitive to reverse the axes so that the map's orientation matches vessel orientation indicators (such as the "compass").

The current orientation is indicated by a symbol in the top-right of the map, which displays REV when in reverse orientation mode and STD when in standard orientation mode. Tapping the symbol toggles between the modes.
