ATAK plugin development, Cursor on Target protocol, offline-first architecture for denied environments, and ruggedized UX design for operators in the field.
Tactical software runs in conditions that break most mobile applications: intermittent or absent connectivity, physical stress on hardware, operators in gloves using displays in direct sunlight, and time pressure that makes UX errors operationally consequential. Building for the field means designing for failure modes that lab testing never surfaces.
ATAK (Android Team Awareness Kit) is the standard tactical awareness platform for ground forces in NATO-aligned militaries. Custom ATAK plugins extend its capabilities — adding unit-specific data feeds, sensor integrations, and mission tools while leveraging ATAK's existing map, communication, and Cursor on Target infrastructure. CoT protocol defines how position, tracks, and sensor data are exchanged across the tactical network.
Articles in this section cover ATAK plugin development from architecture to deployment, CoT protocol implementation, offline-first application design for communications-denied environments, data synchronization patterns, and UX principles for tactical software used by operators under stress.
ATAK (Android Team Awareness Kit) is an Android-based mobile geospatial platform originally developed by the US Air Force and now widely used by NATO and allied forces for tactical situational awareness. It displays Cursor on Target (CoT) tracks on an offline map, supports MEDEVAC, CASEVAC, SALUTE reports, and integrates with radios, drones, and C2 systems via a plugin architecture. Corvus Intelligence specializes in ATAK plugin development for custom sensor and data integration requirements.
+What is offline-first design in tactical mobile apps?
Offline-first means the application is designed to function fully without network connectivity — all required maps, data, and logic reside on the device. Sync occurs opportunistically when connectivity is available, using conflict-resolution logic to merge changes made during disconnected operation. In tactical field apps, offline-first is not a feature but a baseline requirement: operators in contested RF environments cannot depend on network availability for mission-critical functions.
+What are MBTiles and PMTiles for offline maps?
MBTiles and PMTiles are file formats for storing pre-rendered map tiles in a single portable file that can be loaded on a device without internet connectivity. MBTiles uses SQLite as its container; PMTiles uses a cloud-optimized binary format that supports HTTP range requests. In tactical apps, these formats allow operators to carry high-resolution terrain maps, satellite imagery overlays, and custom tactical graphics on their Android devices — ready to use when the network is unavailable.
+What is Cursor on Target (CoT)?
Cursor on Target is a standardized XML message schema used to exchange real-time position, status, and event data between tactical systems. A CoT event carries: a unique identifier (UID), position (latitude, longitude, altitude, and circular error), timestamp, and a type code (friend/hostile/neutral/unknown + entity type). CoT is the native messaging format of ATAK and is supported by most modern NATO-compatible C2 and field application platforms.
+What is WinTAK and how does it differ from ATAK?
WinTAK is the Windows desktop version of the Team Awareness Kit — functionally equivalent to ATAK but running on Windows laptops and workstations. It is used at command posts and vehicle platforms where ruggedized Android devices are not suitable. Both ATAK and WinTAK share the same CoT messaging protocol and plugin API, so plugins developed for one platform can typically be ported to the other. Corvus Intelligence develops plugins for both ATAK and WinTAK environments.
+What is MANET and how is it used in tactical communications?
A MANET (Mobile Ad Hoc Network) is a self-configuring wireless network where each node — soldier radio, vehicle, drone — acts as both a host and a router, relaying traffic to nodes out of direct radio range. MANETs are used in tactical environments where fixed infrastructure (towers, cables) is unavailable. Tactical field apps connect to MANETs via IP-over-radio links to exchange CoT tracks, voice, and data with other units without relying on cellular or satellite connectivity.
+How do tactical field apps work in GPS-denied environments?
In GPS-denied environments (caused by jamming or terrain masking), tactical field apps maintain operator position using alternative methods: inertial navigation (IMU-based dead reckoning), manual position entry, range-bearing reports from known landmarks, or relative positioning from peer radio nodes. Offline maps remain fully functional regardless of GPS availability, and CoT tracks from other nodes continue to be received over MANET links as long as radio connectivity is maintained.
+What is ruggedized UX for military operators?
Ruggedized UX means designing touch interfaces for operators wearing gloves, working in low-light conditions, under cognitive stress, and on ruggedized devices with smaller screens. Design principles include: minimum touch target size of 48px (larger for glove operation); high-contrast color schemes readable in direct sunlight; limited information density per screen; one-hand operation support; and large, clearly labeled action buttons for critical functions. Standard mobile UX guidelines are insufficient — ATAK's UI patterns are the reference baseline for tactical apps.
+What is the ATAK plugin development model?
ATAK's plugin architecture allows third-party developers to add custom functionality — new map overlays, sensor integrations, report templates, radio interfaces — without modifying ATAK core code. Plugins are standard Android APKs that register with ATAK via a published API. They can subscribe to CoT events, display custom overlays on the map, open side panels, and communicate with external systems over TCP/UDP. Corvus Intelligence builds custom ATAK plugins for sensor integration, C2 connectivity, and specialized operational workflows.
+What tactical field application development services does Corvus Intelligence provide?
Corvus Intelligence builds ruggedized, offline-first mobile applications for operators at the last tactical mile — Android (ATAK plugins, standalone apps), WinTAK plugins, and cross-platform tactical tools. Development covers CoT integration, MANET connectivity, offline map management (MBTiles/PMTiles), glove-friendly UX, and integration with C2 systems, drones, and radio networks. The company is an accredited Brave1 member with direct operational feedback from Ukrainian armed forces field deployments.
