How does nNav navigate without GPS?

nNav uses a proprietary onboard vector database to match live camera frames against pre-indexed satellite imagery. Position is derived from visual pattern matching rather than satellite signals, making it immune to jamming, spoofing, and meaconing.

What position accuracy does nNav achieve?

nNav achieves sub-1 meter position accuracy in GPS-denied environments. This precision is maintained throughout the mission across varied terrain, lighting conditions, and weather.

Does nNav require a network connection during flight?

No. The entire area of operations reference map is loaded onto the device before flight. nNav operates in full EMCON alpha: nothing is transmitted or received mid-mission.

What is AutoNav and how does it relate to nNav?

AutoNav is the proprietary visual positioning capability that powers the nNav product line. All AutoNav technology, proof points, and mission history are now carried under the nNav brand.

Q: What autopilot systems does nNav work with?

nNav integrates with PX4 and ArduPilot via standard MAVLink v2 over UART, UDP, or TCP. Compatible with QGroundControl, Mission Planner, and custom GCS implementations without any firmware modification.

Navigate without GPS. Operate without limits.

Position from what the drone sees, matched against an onboard map. No satellite signal, no cloud dependency, no transmissions. Sub-meter accuracy in environments where GPS has no reach.

Technology

How nNav Navigates

Proprietary hardware, a custom vision model, and multi-vector search — all running onboard, offline.

Proprietary Edge Hardware

Endee's purpose-built edge module pre-indexes millions of geo-referenced satellite vectors onboard — no cloud, no uplink, zero RF emissions from takeoff.

Proprietary HW

Custom Vision Model

Each live camera frame is encoded by Endee's custom aerial vision model, purpose-trained on satellite and drone imagery across seasons, altitudes, and lighting conditions.

Custom AI Model

Multi-Vector Search

The frame embedding is matched against the onboard map using Endee's multi-vector search engine — combining visual, spatial, and contextual vectors for sub-meter precision under adversarial conditions.

Multi-Vector

Sub-Meter Position Fix

The matched coordinate is resolved inside a secure enclave on Endee's proprietary hardware and injected directly into the flight controller via MAVLink — no decryption outside the device.

Sub-1m

Immune to Jamming and Spoofing

No satellite signal enters the navigation loop. The system cannot be jammed, spoofed, or deceived through signal manipulation. Position is derived entirely from optical pattern matching against an onboard map.

Fully Silent. EMCON Alpha.

The entire area of operations map loads before flight. Nothing is transmitted mid-mission. No RF emissions, no cloud requests, nothing to geolocate or intercept. Invisible by design.

Continent-Scale Coverage Onboard

Proprietary 20x compression puts up to 1,000,000 km² of satellite reference data on a single low-power edge device. The area of operations can grow without any latency ceiling or bandwidth constraint.

Sensors and Coverage

Day, Night and All Conditions

Full Daylight

Standard camera feeds capture high-contrast imagery matched against satellite reference tiles in real time.

Night and Low Light

Thermal and low-light sensors take over when ambient light drops to near zero, reading heat signatures instead of reflected light.

Multi-Sensor Fusion

Thermal, low-light, and barometric sensors fuse natively into one unified vector space for continuous position awareness.

Integration
