GPS-Denied Autonomy is Powered by Machine Vision Systems

Multiple machine vision based technologies combined with navigation algorithms to deliver GPS-Denied autonomy. Without detecting and tracking objects and features in the environment around the UAV, navigation algorithms wouldn't be able to guide in accordance with its mission.

Autonomy in New, Unmapped Flight Terrain

In unknown and unmapped flight systems, the same methodology is deployed on the edge, and optionally across mesh-networked UAV. When no pre-flight spatial data exists, drones map the area they've flown through and use extracted visual feature-sets for precise reference of movement versus an initial location. The map created during flight can be used on subsequent missions and any other connected UAV.

Autonomy & Positioning without GPS

Rhoman's shared memory system allows drones to use 3D spatial maps (Google Earth, pre-created Digital Twins from reconnaissance, other gathered data) to perform autonomous missions without GPS. The system let's drones
 

  • Use their existing cameras to identify objects and terrain feature-sets in the real world

  • Compare that environmental detections with stored 3D data (locally stored or updated over 5G for long, commercial flights)

  • Estimate a continuously running GPS-free position estimate

  • Maintain positioning and awareness to complete missions and maintain full capabilities when GPS is blocked or spotty

Vision Navigation & Visual Breadcrumbs,

UAV Shared Memory & Autonomy 

Every drone flight is just as safe, or just as dangerous, as that drone's first flight. Shouldn't drones learn from their experience to get better and safer over time?

The Rhoman system provides Flight Muscle Memory, Perception & Awareness, and UAV Memory & Self-Learning to make drones safer, able to understand their environment, and able to execute complex flight maneuvers for performance and safety with and without GPS. 

Shared situational awareness (SA) can support decision makers, individual drones flying through a repeat area... and collaborative swarms; including in GPS-Denied environments.

The unique combination of 1) ML-adaptive controls, 2) tuning from prior and shared flight data, and 3) macro-system data-share allow Rhoman and our partners to create a system that fills future needs as commercial UAV expand in urban, suburban, and contested flight-space areas.
 

Synthetic GPS
Rhoman uses it's network and experience with underground terrain mapping to merge environmental data into a shared network of geo-tagged point clouds and a recognizable camera/LIDAR digital twin of flight engagement areas shared UAV network-wide.

Drone-Drone Interaction
"If every drone had experienced hundreds of autonomous drone-drone interactions, and learned from the encounters - imagine the smooth, autonomous aerial traffic we'd have." Rhoman's system shares our UAV-UAV interaction data network wide.

Drone-Drone Interaction & Swarms

Trustworthy Autonomy
Constraint Barrier Functions
deployed through Rhoman's adaptive controllers - and tuned using Rhoman's network amd shared data systems - provide trustworthy autonomy for BLOS autonomous missions in complex airspace.

Safe & Trustworthy Autonomy

New Capabilities
Because we deploy our capabilities through software and maintain networks with UAV, our systems are uniquely able to connect with drone hardware, sensors, and compute elements in order to deploy future AI technologies and algorithms as they arise.
