Products2

Cyclops

Theseus

Software-first visual positioning product that matches live EO or LWIR imagery to pre-generated reference maps and outputs position over MAVLink on NDAA-compliant commodity hardware.

Maturity not rated

Micro VPS (Micro Visual Positioning System)

Theseus

Pod-mounted visual positioning system that compares camera imagery with onboard satellite maps to give drones position without GPS; flown 564 km over Florida in March 2026.

Inputs this technology depends on. Select a sortable column heading to sort.
			Why it constrains
Edge AI compute modules	Component	High	Map matching runs on board; Theseus says its software runs on a Raspberry Pi 5.
GNSS signals	Infrastructure	High	Substitutes for GNSS when it is jammed; COMPASS emulates a GPS antenna output.

Criticality is how much a shortage would constrain production; open an input for producers, concentration and trade controls.
