Overview

Jamming a satellite receiver is cheap and increasingly common. Most unmanned aircraft respond by refusing to arm, drifting, or landing where they stand. A spoofed signal is worse than none at all, because the aircraft confidently flies to the wrong place.

This platform treats satellite navigation as one input among several. Downward and forward cameras measure motion against the ground, an inertial unit carries the solution between fixes, and the flight controller cross-checks every source against the others. When the satellite signal disagrees with what the aircraft can see, the signal is the one that gets dropped.

System qualities

/ 04

Sees the ground move

Visual motion against terrain, fused with inertial measurement, holds position and follows a route with no satellite input at all.

/ 04

Rejects a lie

A spoofed position disagrees with the inertial and visual solution. The aircraft detects the disagreement and discards the false fix instead of chasing it.

/ 04

Returns without help

Home is remembered as a visual and inertial route, so return-to-launch still works in a denied environment.

/ 04

Link loss is not mission loss

If the control link drops, the aircraft completes the planned task and comes back, rather than stopping at the point of loss.
