The Rhoman team has over 35 years of aerospace experience, and combines 3 key technologies to deliver essential point solutions for immediate UAV needs, and future solutions to scale drones into new commercial markets.


Who We Are

Rhoman Aerospace develops innovative vision-based flight control, autonomy, and navigation solutions for drones. Our solutions deploy via software download, use the existing camera(s) on a drone, and allow the drone to visually track it's relative position or exact location without GPS, for trustworthy, entirely hands-free operations in contested airspace.

How We Got Started

Rhoman Aerospace began in 2015 with the filing of its first patent for innovative UAV flight control and stability systems to handle shifting cargo payloads. The Company used these initial technological innovations towards the development of heavy-lift UAVs for cargo delivery operations, resupply operations to US Army frontlines, and distributing resources after natural disasters. 

Since that time, the Company has re-focused our mission towards what we do best; developing complex drone flight control systems at scale. Our mission is to leverage the most robust flight control systems and concepts in the world to develop the safest and most efficient UAV flight control solutions on the market, and to make our solution accessible to all drones, regardless of size or configuration.
