NASA is collaborating with wildfire response teams to create advanced drone technology that can enable 24-hour fire suppression operations.
Aerial firefighting at present is limited to daylight hours because of visibility issues at night and the additional risk of hitting terrain or other flying objects.
NASA is testing airspace management technology that will enable drones to operate around the clock safely, even when visibility is limited.
The Portable Airspace Management System (PAMS) consists of a secure set-up for drone pilots, including an ADS-B receiver, a computer, and a mesh radio network for easy communication between nodes and, most importantly, an automated way of developing flight plans to minimize any airborne collisions.
Scientists working on the Advanced Capabilities for Emergency Response Operations (ACERO) program hope to refine these concepts with more testing, with the long-term goal to transfer the technology to firefighting agencies for use in suppressing wildfires and reducing their impact.
At NASA's Ames Research Center, three PAMS units were compatible, and researchers verified each other's flight paths, ensuring that every system had shared information through a mesh radio network.
The PAMS is ideally developed into a rugged, portable container that can be used in various weather conditions, making it easy to deploy in the field.
PAMS soon passed trials held to evaluate its effectiveness, including one in Monterey Bay Academy Airport in Watsonville, California, where battlefield simulations were held, and real-world firefighting scenarios were made.
By sharing real-time data about aircraft location, the airborne relay is fast becoming an essential tool for anyone involved in wildfire operations.
The PAMS offers valuable references for analyzing the development of air defense operations concerning firefighting in the coming years.
