DCS Airspace for DCS World ATC, AWACS and GCI

DCS Airspace is a free, web-based real-time ATC, AWACS, and GCI software client for DCS World, developed as part of the Combined Ops suite. It provides a dedicated radar and airspace-control workstation for virtual air traffic controllers, Airborne Warning and Control System (AWACS) operators, and Ground-Controlled Interception (GCI) operators. Its browser-based interface supports real-time airspace monitoring, aircraft identification, tactical track management, traffic coordination, and interception operations in DCS World multiplayer missions, including large-scale campaigns involving multiple flights, squadrons, pilots, and controllers.

DCS Airspace combines DCS-native sensor detection data with terrain-based radar visibility analysis. It presents contacts detected by the DCS World simulation and provides radar line-of-sight (LOS), terrain masking, and radar coverage analysis to help operators assess radar visibility and terrain-related coverage across the simulated operational area.

DCS Airspace is designed around fidelity to the DCS World simulation. Its tactical air picture reflects the sensor-detection state reported by the simulation, rather than replacing native DCS World detection with an independent external radar-detection model.

DCS Airspace has been designed and developed through experience gained in large-scale DCS World multiplayer campaigns involving more than 100 pilots and controllers, and continues to be used in these operational environments. This experience informs its real-time control interface, tactical workflows, and multi-controller coordination capabilities.

For AWACS and GCI operations in DCS World, DCS Airspace combines native sensor-detection data with advanced aircraft identification, supporting DCS (Simplified) and REAL (Advanced IFF-based) modes. REAL mode uses IFF and transponder data received through Simple Radio Standalone (SRS), with manual controller identification, IFF authentication, and correlation with the Air Tasking Order (ATO). Tactical control features include free-hand BRAA measurements, persistent track-to-track BRAA calculations, automated AWACS/GCI PICTURE generation, and track-to-track intercept Cut-Off calculations. Shared tactical functions include Groups of Responsibility and Targeted Tracks, while Tracks of Interest support individual operator monitoring. Additional capabilities include Airspace Control Order (ACO) visualization, threat circles, friendly Integrated Air Defense System (IADS) control, supported Rules of Engagement (ROE) controls, and Simple Radio Standalone (SRS) integration.

For ATC operations in DCS World, DCS Airspace supports Ground Control, Tower Control, Departure, Approach, and Area/Radar Control. Its airport ground view displays airfield layouts, runways, taxiways, aircraft, and ground traffic, helping controllers monitor and coordinate ground movements, taxiing, takeoffs, and landings. Flight schedules and flight plans provide additional information for coordinating planned departures and arrivals with live traffic.

For approach control and precision approaches, DCS Airspace provides a Precision Approach Radar (PAR) display simulation reproducing the characteristic azimuth and glide-slope presentation of a real PAR controller display. It supports precision approach monitoring and controller-guided aircraft alignment with the runway, including in instrument meteorological conditions (IMC).

Additional ATC navigation capabilities include IFR and VFR reference points, Local Navigation Points, and configurable Custom Reference Points for navigation, traffic reporting, and approach, arrival, and departure coordination. Together with airport ground visualization, flight schedules, flight plans, and real-time aircraft monitoring, these features support ATC operations from ground movement and takeoff through departure, area control, approach, and landing.

DCS Airspace offers realism, operational, and access-control settings to adapt its behavior to different DCS World multiplayer environments. These settings include DCS (Simplified) and REAL (Advanced IFF-based) aircraft identification, configurable friendly AI identification, and optional automatic AWACS/GCI PICTURE generation (Auto PICTURE).

Additional options control station selection and map access, including whether users can enter the map through stations without an actual geographic position and whether they can switch stations directly from the map. These settings also affect how Simple Radio Standalone (SRS) calculates line of sight (LOS). Further configuration options allow administrators to manage player information display and adapt the workstation to their operational requirements.

Server access permissions can restrict access according to host group membership or, when a DCS AOC Tools Project is linked, operation registration, coalition, and controller role. This allows virtual squadrons to configure access for public training environments or more controlled multiplayer operations. Learn about the DCS Airspace Permissions System

DCS Airspace integrates with the Combined Ops mission-planning and operational workflow through DCS Olympus, DCS AOC Tools, and DCS Mission Planner. It communicates with the DCS World server through DCS Olympus and can use available mission and operational data provided by AOC Tools and Mission Planner, including Air Tasking Orders (ATO), Airspace Control Orders (ACO), Special Instructions (SPINS), Communication Plans (Comm Plans), flight plans, and mission information. This connects mission preparation and planning data with real-time ATC, AWACS, and GCI operations during the mission.

The shared operational interface helps controllers, AWACS/GCI operators, pilots, and squadron staff work from coordinated mission information during DCS World multiplayer operations. Operators can monitor aircraft activity, manage flights and tactical tracks, review mission data, and perform airspace-control tasks from the same browser-based workstation. Keyboard shortcuts are also available for supported actions that need to be performed quickly during live missions.

Interactive Radar and Airspace Map

The interactive map is the primary ATC, AWACS, and GCI control interface in DCS Airspace, providing a real-time operational picture of the simulated DCS World airspace. Its map display supports air traffic control, tactical monitoring, and military airspace management, with map styles and overlays designed to support controller situational awareness rather than simply display geographic information.

Users can switch between available map backgrounds, including native DCS World terrain maps and a dark tactical radar display for ATC, AWACS, and GCI operations. Configurable map layers and overlays provide control over the visibility and opacity of airspace-control measures, mission information, and tactical data. Combined with contact filters and visual and audio alerts, these display options help operators maintain situational awareness and focus on relevant air traffic and tactical contacts during live DCS World missions.

Custom Map Views allow users to save and restore up to three personalized map configurations. Each saved view can include the map center and zoom level, map type, layer settings, and supported tactical reference settings. Controllers can quickly switch between saved views to return to different operational areas and map configurations during ATC, AWACS, and GCI operations.

Integrated tactical navigation and reference tools include multiple Bullseye references, a configurable Custom Reference Point, distance measurement, free-hand BRAA measurements, persistent track-to-track BRAA calculations, and track-to-track intercept Cut-Off calculations. True and magnetic bearing calculations, together with WGS84 coordinates and MGRS grid overlays, provide additional navigation and positional reference capabilities for ATC, AWACS, and GCI operations.

Airspace Control Functions

DCS Airspace provides the core functions required for AWACS and GCI control, allowing operators to maintain a live tactical air picture, manage contacts and tracks, identify aircraft, coordinate airspace, and control intercept operations.

The multi-controller architecture supports a shared tactical picture while allowing individual operators to maintain their own areas of responsibility and tracks of interest. Groups of Responsibility and Targeted Tracks can be shared between connected controllers with dedicated tactical symbology, while Tracks of Interest remain operator-specific. This allows multiple ATC, AWACS, and GCI operators to coordinate within the same live airspace environment without losing their individual operational focus.

Advanced C2 capabilities extend the airspace-control workflow beyond basic track display, including shared track management, mission data integration, intercept geometry, ACO visualization, and direct control of friendly IADS units.

AWACS and GCI Control Features

  • Advanced IFF Identification, Transponder Codes and ATO Correlation — provides two identification realism levels for DCS World air traffic control, AWACS and GCI operations: DCS (Simplified), which uses identification information provided directly by the simulation, and REAL (Advanced IFF-based), which interprets available IFF and transponder data received through Simple Radio Standalone (SRS). In REAL mode, radar tracks can be assigned one of six identification statuses: Friendly, Assumed Friendly, Unknown, Pending, Hostile and Suspect (Learn about DCS Airspace Tactical Symbology), allowing controllers to distinguish confirmed friendly contacts, presumed friendly contacts, unidentified tracks, contacts awaiting identification, confirmed hostile contacts and suspected hostile contacts. Track identification can be performed manually or supported by automatic IFF Mode 4 authentication, Mode 3 transponder code correlation with the Air Tasking Order (ATO) and Mode S data retrieval. Mode 3 and ATO correlation can provide available mission information, including callsign, aircraft type and mission details, but ATO correlation alone does not automatically authenticate a track as Friendly or Hostile. DCS Airspace also supports the recognition of special transponder codes, including 7700 (Emergency) and 7600 (Radio Failure), as well as IDENT indication, providing controllers with additional information for radar track interpretation and identification. Server-wide settings allow administrators to configure how friendly AI aircraft are identified when reliable IFF or Link 16 state is unavailable. Identified tracks can retain their identification even if an aircraft subsequently deactivates its IFF or onboard systems, with dedicated hollow symbology distinguishing persistent identification from active sensor detections. These capabilities combine IFF authentication, radar track identification, transponder code recognition, emergency squawk detection and mission-data correlation to support realistic radar-based airspace control in DCS World.

REALISM & DCS WORLD DATA ACCURACY
A shared technical foundation that gives ATC, AWACS and GCI operators accurate DCS World terrain data, simulation data and sensor detection data for real-time radar operations, detection, identification, airspace control and tactical coordination. DCS Airspace separates live DCS World detection from its own terrain and tactical analysis. The live tactical contact picture is based on the sensor detection data generated by the DCS World simulation, while DCS Airspace uses DCS World terrain data to provide additional terrain-aware analysis for radar coverage, Line of Sight, and terrain masking.

LARGE-SCALE DCS WORLD OPERATIONS

DCS Airspace supports real-time ATC, AWACS and GCI operations, from small missions to large-scale DCS World events involving 100+ pilots and controllers. Its browser-based tactical radar workstation helps controllers monitor live contacts, identify aircraft, coordinate intercepts and maintain shared tactical awareness.

DCS-NATIVE DETECTION DATA

Uses the sensor detection state reported directly by DCS World as the authoritative source for the live tactical picture. DCS Airspace does not replace the simulation with an independent radar-detection model: it displays and operates on the contacts that DCS World determines its sensors and units can detect, preserving native simulation fidelity for ATC, AWACS and GCI operations.

DCS-NATIVE SRTM1 TERRAIN DATA

Uses SRTM1 elevation data extracted from DCS World terrain as the basis for terrain-aware analysis. This terrain data is used throughout DCS Airspace for radar Line of Sight, terrain masking, radar coverage and point-to-point visibility analysis, keeping terrain calculations consistent with the active DCS World theater.

POINT-TO-POINT LOS ANALYSIS

Allows controllers and tactical operators to analyze line of sight between arbitrary locations and altitudes using DCS World terrain data and a spherical radar coverage model. The analysis accounts for terrain obstruction and the effect of altitude differences on the maximum horizontal detection range, supporting radar and airspace assessment.

TERRAIN MASKING ANALYSIS

Evaluates how terrain affects Line of Sight between sensors and contacts, identifying areas where terrain can obstruct radar or other sensor coverage. This terrain-aware analysis uses DCS World terrain elevation data and can be used to assess radar coverage, terrain masking and low-altitude detection conditions.

MISSION-DATE MAGNETIC VARIATION

Calculates magnetic variation using IGRF magnetic-field data based on the mission location and date. This allows magnetic headings and bearings to reflect the magnetic variation applicable to the specific DCS World mission rather than relying on a fixed or generic value.

NATIVE DCS MAPS

Uses native DCS World map references where available, keeping geographic and tactical information aligned with the active DCS World theater. This provides controllers and tactical operators with familiar map references consistent with the terrain and coordinate data used by the simulation.

ATC / GCI / AWACS RADAR DISPLAY

Provides an ATC, AWACS and GCI-oriented radar display designed for real-time air traffic control, tactical airspace management, contact monitoring, identification and air battle management within DCS World.

CUSTOMIZABLE TACTICAL DISPLAY

Provides a configurable tactical radar display with independent visibility and opacity controls for ACO, drawings, airbases, threat circles and other operational overlays, allowing controllers to keep the live air picture focused on the information required for ATC, AWACS and GCI operations.

UTM-CALIBRATED DATA

Coordinate calculations are calibrated to the UTM zone used by the active DCS World theater, ensuring that geographic positions and tactical measurements remain consistent with the selected map and mission environment.
Shared technical foundation: Combined Ops uses DCS World simulation data and DCS-native geographic references across its operational tools, with each tool applying them to its specific mission role.

Detection Realism Through DCS World Simulation Fidelity

DCS Airspace uses the native sensor-detection state reported by DCS World to determine which contacts appear in the operational picture. It does not substitute an independent external radar-detection model for the simulation's own detection logic. Learn about Radar Contact Visibility Logic

Separate radar line-of-sight (LOS), terrain masking, and radar coverage analysis capabilities allow operators to assess terrain-related radar visibility across the simulated operational area. Radar LOS analysis can also evaluate a selected radar against a configured target altitude using a spherical coverage model. These analytical capabilities complement native DCS World detection rather than overriding it.

Why DCS Airspace Uses DCS Olympus

DCS Airspace uses DCS Olympus to communicate with the DCS World server and obtain the live simulation data required for its real-time airspace picture. Olympus provides the connection between the running DCS World mission and the browser-based ATC, AWACS, and GCI workstation, allowing operators to monitor the simulated airspace and use the operational features available in DCS Airspace.

Where a DCS World server already runs DCS Olympus, DCS Airspace can use that existing server-side component instead of requiring a separate dedicated server component for its current integration. This can simplify deployment for communities that already use Olympus as part of their DCS World server infrastructure.

Combined Ops and its tools (DCS AOC Tools, DCS Mission Planner and DCS Airspace) are developed and maintained solely and exclusively for DCS World as a platform for digital entertainment and flight simulation. Our operations are strictly non-commercial and non-military. Under no circumstances is our environment intended, nor should it be used, for commercial purposes, professional pilot training, or any military applications. We are a community of enthusiasts dedicated to the hobby of flight simulation, and all our activities are conducted purely for recreational and educational enjoyment within the gaming community.
