DCS Airspace

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 realistic radar and airspace-control workstation for controllers and tactical operators, with the functions required to monitor, identify, coordinate, and control air traffic and tactical airspace during multiplayer missions.

Its realism is based on fidelity to the DCS World simulation: DCS Airspace does not attempt to recreate the real world independently, but provides controllers with an operational interface built around the data and behavior generated by the DCS simulation itself.

The system provides a shared real-time tactical picture for air traffic control, airspace management, airborne surveillance, ground-controlled interception, and tactical coordination. Controllers can manage aircraft, flights, approaches, tracks, airspace, and engagements from a single browser-based interface.

DCS Airspace connects to DCS World through DCS Olympus and can use operational mission data from DCS AOC Tools and DCS Mission Planner, allowing the controller's tactical picture to be integrated with the wider Combined Ops mission-planning workflow.

DCS Airspace brings mission, flight, and airspace information together in a single operational interface. It can display data from DCS AOC Tools and DCS Mission Planner, including Air Tasking Orders (ATO), Airspace Control Orders (ACO), SPINS (Special Instructions), Communication Plans (Commplans), flight plans, and mission information. This allows ATC, AWACS, GCI operators, pilots, and squadron staff to work from the same operational information during a DCS World mission.

The interface provides real-time information about the mission environment while keeping commonly used airspace and tactical data immediately available to controllers. Operators can monitor aircraft activity, manage tracks and flights, coordinate traffic and airspace, review operational data, and perform tactical control tasks without leaving the same workstation. Keyboard shortcuts are also supported for actions that need to be performed quickly during a live mission.

Why does DCS Airspace use the DCS Olympus server?

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. The architecture provides the external ATC, AWACS, and GCI interface while keeping the additional processing required on the DCS World server as low as possible. This helps maintain a responsive DCS World mission while providing controllers with the live information required for realistic airspace control and tactical operations.

Another advantage is that DCS Olympus is already used by many virtual squadrons and DCS World communities as part of their server infrastructure. DCS Airspace can therefore use an existing DCS Olympus server instead of requiring the installation and operation of a separate dedicated server component. This simplifies deployment and avoids adding another server-side application and additional workload to the DCS World server environment.

DCS Airspace main features

Interactive Radar and Airspace Map

The interactive map is the primary ATC, AWACS, and GCI control interface for viewing and managing the DCS World airspace. Users can switch between different map backgrounds, including satellite imagery, an AWACS-style air picture, and native DCS World terrain. The interface provides tools for measuring distance and determining both true and magnetic bearings, while WGS84 and MGRS grid overlays provide navigation and tactical references. Individual map layers and overlays can be adjusted independently to keep airspace, mission, and tactical information clearly visible.

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
  • Multiple Bullseyes — switch between configured Bullseye references during a mission for consistent tactical positioning and reporting.
  • Identification system — identify tracks manually or through automatic IFF Mode 4 interrogation. IFF Mode 3 codes are automatically correlated with the Air Tasking Order (ATO), providing mission data such as callsign and mission type. Once identified, tracks remain identified even if the aircraft deactivates its IFF or onboard systems, with dedicated hollow symbology distinguishing persistent identification from active sensor detections.
  • BRAA — continuously calculate track-to-track bearing, range, altitude, and aspect information or perform free-hand measurements for tactical coordination.
  • Intercept cut-off points — continuously calculate and display track-to-track intercept geometry and cut-off information to support tactical intercept planning.
  • Group of Responsibility — assign groups of contacts to an operator's area of responsibility and share those assignments with other connected controllers through dedicated tactical symbology.
  • Tracks of Interest — mark individual tracks for personal monitoring without changing the shared tactical picture. Dedicated symbology keeps operator-specific contacts clearly identifiable.
  • Targeted Tracks — designate tracks as operational targets and share the designation with other connected controllers through dedicated tactical symbology.
  • Flight and mission data — view active flights, flight plans, and mission information relevant to the current tactical air picture.
  • ACO layers — display and customize Airspace Control Order layers according to mission requirements, keeping established airspace measures visible alongside the live tactical picture.
  • Threat circles — display known or detected threat areas directly on the tactical map for airspace awareness and engagement planning.
  • IADS control — directly control friendly IADS units from the tactical map, including activating or deactivating SAM batteries during the mission.
  • Contact filters — filter contacts by altitude, speed, and type while preserving the visibility of Tracks of Interest and Groups of Responsibility through dedicated symbology.
  • Visual and audio alerts — receive visual and audible notifications for new contacts and other relevant mission events requiring operator attention.
  • DCS-native sensor detection — use the detection state reported directly by DCS World rather than replacing the simulation's sensor-detection logic with an independent external radar model. The controller therefore sees the sensor picture generated by the DCS simulation itself, preserving fidelity to what each DCS sensor or unit has actually detected. This is a fundamental part of the realism of DCS Airspace: the tactical picture follows the simulation state of DCS World rather than an independent real-world radar model.
  • Extensive keyboard shortcuts — use dedicated keyboard shortcuts for the main tactical and interface functions, enabling rapid access to essential controls, reducing mouse interaction, and supporting efficient operation during high-workload ATC, AWACS, and GCI scenarios.
REALISM & DCS WORLD DATA ACCURACY
A shared technical foundation that gives ATC, AWACS and GCI operators accurate DCS World terrain, simulation and sensor data for real-time radar operations, detection, identification, airspace control and tactical coordination.

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 presents and manages 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 high-fidelity SRTM1 elevation data from the actual DCS theater for terrain elevation, line-of-sight and terrain-masking analysis, keeping geographic calculations aligned with the simulated environment used by controllers and tactical operators.

REAL-TIME RADAR LOS

Provides terrain-based line-of-sight analysis using DCS World terrain data to support radar, sensor and tactical airspace assessment. The analysis complements the live sensor picture provided by DCS World rather than replacing its detection logic.

POINT-TO-POINT LOS ANALYSIS

Allows controllers and tactical operators to analyze line of sight between arbitrary locations and elevations for radar, sensor and airspace assessment using DCS-native terrain data.

TERRAIN MASKING ANALYSIS

Helps controllers assess how DCS World terrain affects radar and sensor visibility, supporting tactical interpretation of terrain masking across the operational area.

MISSION-DATE MAGNETIC VARIATION

Keeps tactical headings and bearings consistent with the magnetic variation applicable to the mission date, supporting accurate radar-control and airspace operations.

NATIVE DCS MAPS

Provides controllers with native DCS World map and theater references that correspond directly to the simulated operational environment, including airport diagrams for detailed airfield and ground-control operations.

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

Maintains coordinate and geographic consistency between the tactical radar display, airspace calculations and the active DCS World theater.
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

For contact detection, realism means fidelity to the DCS World simulation. Instead of replacing DCS World's sensor and detection logic with an independent external radar model, DCS Airspace uses the detection state generated directly by DCS World and presents that information through a dedicated controller workstation.

This approach keeps the controller's tactical picture consistent with the simulation itself. Detection, sensor availability, terrain effects, aircraft state, and other mission conditions remain those produced by DCS World, while DCS Airspace provides the tools required to interpret, identify, manage, and control the resulting air picture.

The result is a realistic ATC, AWACS, and GCI environment within the DCS World simulation: the system does not attempt to model a separate real-world environment alongside DCS World, but instead builds the controller's operational experience around the data and behaviour of the simulation.
