At the MAVLink-Military Integration Hackathon, sponsored by Auterion and the DroneCode Foundation, teams from smaller companies and specialized builders integrated autonomous systems that would ordinarily take months to coordinate. Across two days, they built working end-to-end demonstrations and flew them live.
One team built a fully integrated swarm demonstration in 38 hours. Another composed of three companies working together took separate payload and platform components, wired them together using MAVLink-M, and demonstrated coordinated strike capabilities through a modified ground control interface. A third showed how 3D-printed modular drones could swap payloads without custom engineering for each integration.
Government observers were on site taking notes. Acquisition officers were reviewing systems. And the press release that followed was signed by 14 companies, each willing to publicly endorse an open, shared standard.
Pramod Raheja, CEO of Airgility and Autonomy Global Ambassador for Autonomy was also on the ground and provided the insights for this article. “Interoperability is becoming a strategic requirement, not a nice-to-have,” he said. “No single company is going to provide every autonomous platform. Future operations require drones, ground robots, sensors, C2 systems and AI from many vendors to work together, and open interfaces dramatically reduce the integration time that stands in the way.”
MAVLink 2 vs. MAVLink-M: What’s Actually New
A point of confusion surfaced repeatedly at the event, whether or not MAVLink-M is a replacement for MAVLink 2. It is not. It is an extension of it. And that distinction is the whole reason the approach works, Raheja explained.
MAVLink 2 is the underlying transport protocol, the over-the-wire framing that has become the de facto standard for how autopilots, ground control stations and payloads talk to each other. It handles the mechanics of flight: telemetry streams, navigation missions, parameter configuration and component status.
MAVLink-M is a specialized message dialect that runs directly on top of it. Whereas MAVLink 2 concerns itself with flying the aircraft, MAVLink-M concerns itself with the mission. It enables a standardized vocabulary for what a platform observes and requests: track identities, targets, structured observation reports and safe arming sequences.
According to Raheja, three design choices make this practically important. Because MAVLink-M rides inside the standard MAVLink 2 frame, it inherits the existing security architecture without modification, including packet signing to authenticate identities and block replay attacks. Legacy systems that don’t speak MAVLink-M can route or bypass those packets safely. They don’t crash and they don’t need upgrading in lockstep. For this reason, adoption happens incrementally rather than through forced migration. And MAVLink-M was designed to translate cleanly through a gateway into the C2 standards defense and public safety agencies already use. It isn’t a walled garden for drone people. It’s a bridge into the networks where operational decisions actually get made.
There is also a deliberate omission worth noting. MAVLink-M excludes internal device configurations, such as performance capacities, laser codes and similar sensitive parameters. That is not an oversight. It lets vendors participate in a shared standard without exposing what makes their hardware competitive. That is precisely why 14 companies were willing to sign on.
The Era of Single-Vendor Solutions Is Ending
For decades, the defense industry ran on a simple assumption that when a complex capability was needed, a prime contractor received the requirements and delivered a monolithic solution. Everything came from one ecosystem. Everything was locked together.
That model is breaking down, not because it is wrong in theory, but because reality demands something faster. Modern operations don’t run on a single platform. They run on heterogeneous fleets of aerial platforms from multiple vendors, ground robots with different sensors, C2 systems from one company and AI modules from another, all of which need to share telemetry and operate under unified command. No single company makes all of it. Waiting for one company to integrate another’s tools takes years.
Raheja believes the hackathon showed what happens when that constraint is removed. Teams did not spend their time negotiating licensing agreements or proprietary interfaces. They built, integrated and flew.
“The military is signaling clearly that open architectures are preferred over proprietary ecosystems,” Raheja said. “MAVLink has become a practical language for autonomous systems because it enables rapid integration across hardware and software stacks. The conversation has shifted from ‘whose ecosystem?’ to ‘how quickly can we integrate?'”
Days Instead of Years
The Auterion swarm demonstration was not a simulation. Three drones flew in formation with collision avoidance, handled sequential tasking against a single target or dispersed targets and used visual navigation with no GPS required for terminal guidance. Each drone locked onto a visual target, maintained the lock through approach and executed. They would abort automatically if the lock was lost. This capability was built in 38 hours and flown live at the Hackathon.
Another demonstration showed an operator workflow that would once have required weeks of custom integration. It involved arming a payload through a ground control user interface (UI,) confirming with an LED on the hardware and triggering through the same interface, all wired through MAVLink-M.
“Rather than multi-year integration programs, teams demonstrated working capabilities in days,” Raheja noted. “That’s the real proof point. Industry and government can rapidly prototype operational solutions when engineers collaborate directly instead of negotiating through contracts.”
The Electronic safe and arm device (ESAD) payload story illustrates this mindset. A munitions vendor arrived late to a previous event, which forced one team to write custom interface code on the fly. Then something happened. The industry standardized around that interface. The next team will not need a week of custom engineering. They will simply plug in and move on.
The pattern repeated over and over. A team that builds modular 3D-printed drones described their old approach. A bespoke protocol layered over MAVLink for every vendor integration, required custom work each time. Standardizing now means customers can drop a new payload onto the airframe and have it work without a systems integrator in the middle.
None of this is achievable under a traditional integration contract on that timeline. In military operations, the environment changes faster than procurement cycles. The ability to prototype working capability in days provides its own kind of advantage.
The Real Tradeoffs
One recurring debate centered on autonomy versus communications. Removing the radio link buys durability. A drone programmed to strike a pre-defined target does not need ongoing comms, which extends lifecycle and removes a major vulnerability. But it also costs adaptive maneuverability. The system cannot react if the situation shifts, the target moves or priorities change mid-flight.
Participants maintained both realities: autonomy that buys durability and communications that buy adaptability. The answer is not to pick one, but to build systems where operators can choose the right tradeoff for the mission. Modern operations will hinge on how targets are represented. This is precisely why a standardized vocabulary for tracking identities and structured observation reports matters as much as the flight protocol underneath it.
AI Only Works If Systems Can Share Data
Autonomy without interoperability presents a false promise, a point that receives less attention than it deserves, in Raheja’s opinion. Autonomous behavior depends on high-quality telemetry, sensor fusion and standardized command interfaces. If every platform is an island, the AI sees a fragmented picture. It can optimize inside its walled garden, but it cannot see the battlefield.
“Autonomous behavior depends on high-quality, standardized telemetry and command interfaces,” Raheja noted. “Protocols like MAVLink let AI access data from diverse platforms instead of isolated systems. Without that, you’re asking an algorithm to make decisions with half the picture missing.”
MAVLink-M changes that equation. It is simple enough to implement, rich enough to handle complex telemetry and open enough that any vendor can build on it. AI systems can pull from drones, ground robots, sensors, gimbal-equipped heavy-lift platforms and C2 networks instead of isolated streams.
The Ecosystem Is Collaborating, Not Competing
Raheja emphasized that the culture of the event was as notable as the technology. Nobody was guarding secrets. Auterion brought the platform and the vision. The participating companies brought the capability and the collaboration.
The exhibitor list tells the story: UVify, Reese, PSA, Fogger FPV (a Croatian manufacturer that has been supplying into Ukraine for years), Arcifer Group, modular drone builders, heavy-lift platforms with gimbal and EOR capability and automated systems shops. These are companies that move fast and are not encumbered by legacy lock-in. They arrived ready to integrate and demonstrate.
“The emphasis wasn’t on competition, it was on creating an ecosystem where capabilities from multiple vendors can be composed together,” Raheja said. “Startups and government engineers were working side by side. That doesn’t happen if everyone is protecting territory.”
That the press release drew 14 signatures and quotes from most participants would not happen in a zero-sum fight. It happened because the question has changed. Not “Do we control the ecosystem?” but “Can we deliver value as part of a larger one?”
Force Multiplication Through Openness
The biggest takeaway wasn’t simply that MAVLink-M works. It’s that interoperability is becoming a force multiplier, according to Raheja. “The future of autonomy won’t be built by a single platform or a single company. It’ll be built on open standards, rapid integration, and collaboration across the entire ecosystem. That’s exactly the direction the defense community is moving, and it’s an exciting time to be part of it,” he noted.
“Events like this reinforce our belief that the future belongs to open, modular autonomy,” he added. “When companies embrace interoperability instead of lock-in, everyone moves faster, from developers to operators to the warfighter.”
The MAVLink-Military Integration Hackathon was not a one-off. It was the equivalent of a bat signal for the autonomy community. Are you ready to answer the call?
