Weatherproofing Drones for Public Safety and All-Weather Operations
Nearly at the same time that drones became popularized, another critical technology emerged: electronic weatherproofing. Through chemical treatments and coatings, electronics can in some cases operate even when fully submerged. For drones—which are often exposed to moisture during misty mornings or rain showers—weatherproofing is invaluable. In public safety missions, where agencies may need to fly in unpredictable or harsh conditions, weatherproofing can mean the difference between a failed deployment and a successful life-saving mission.
Why Weatherproofing Matters
As a veteran peace officer and drone pilot, I know firsthand that during a mission, weather cannot always be controlled. If a drone is needed to save a life, it will be deployed—rain or shine. An untreated drone may survive a mission in poor conditions, but it is highly likely to suffer severe corrosion afterward and may never fly again. By contrast, drones treated to resist weather effects have two major advantages:
- They are more likely to continue operating during the mission
- They are protected against post-flight corrosion, extending their usable life
How Drone Weatherproofing Works
Weather treatments for drones are typically chemical-based and work in two primary ways:
- Polar Bonding: Used for motors and metallic components. Polar bonding compounds adhere to metal surfaces in a similar way magnets attract metal, creating a water-repelling barrier without adding friction or residue.
- Conformal Coatings: Applied to drone electronics such as IMUs (inertial measurement units), autopilots, and power controllers. These coatings act as a thin plastic barrier, sealing components from water while allowing heat transfer. They are thermally rated to withstand high current and operating temperatures.
Regardless of the specific chemical process, drones must be fully disassembled and reassembled for proper treatment. This ensures that every component is protected and the drone functions as intended once reassembled.
Addendum: Advancements in Drone Weatherproofing
Since this article was first written, drone technology has advanced significantly. Many modern platforms now come with built-in weatherproofing, allowing for safe operation in rain, snow, and other challenging conditions. These improvements give public safety agencies greater confidence that their equipment will perform when it matters most.
Additionally, best practices now include using battery and fleet management systems to log and track usage, ensuring balanced cycling and preventing overuse of any single component. At MAXSUR, we not only offer the latest weather-resistant drones, but also have the capability to custom build drones tailored to your agency’s operational requirements.
