Micro VPS Technology

Theseus' Micro VPS solves the key challenge preventing drones from operating reliably in contested environments.

Our Visual Positioning System (VPS) uses cameras, an inertial measurement unit, and pre-loaded satellite imagery to determine it's position and send a simulated GPS signal to any drone.

Visual odometry

Theseus tracks key points from all four onboard cameras from frame to frame to estimate motion relative to the ground. This approach yields a baseline position track that performs exceptionally well at low altitudes and even over feature-sparse terrains or short stretches of water.

Map matching

We compare camera images captured by the Micro VPS’ sensors to a vast onboard database of satellite maps. Our algorithm has been designed to be resilient to variations in the terrain and seasonal changes in the environment. This ensures that we can achieve reliable absolute positioning, cold starts, and effectively recover from faults, regardless of season or terrain modifications.

Real-time fused position

By combining the visual odometry with map matching, we have the benefits of both approaches packaged into a standard NMEA stream that can be read by any flight controller.

Key features

Plug-and-play integration

Theseus’s Micro VPS is designed for effortless installation, allowing quick deployment without extensive modifications or technical expertise. Integrations with PX4 or ArduPilot typically take under 30 minutes.

Immune to jamming

Operate confidently in contested environments with a system that doesn’t rely on vulnerable GPS signals, or any other RF, ensuring uninterrupted navigation.

Versatile for any drone

Compatible with Group 1 drones to light aircraft, Theseus adapts seamlessly to different platforms, enhancing capabilities without hardware limitations.

Ultra-Low SWAP-C

We heavily optimize hardware and software to deliver the lightest, smallest and most power efficient VPS on the market.

Use Cases

Unlock new mission possibilities

Expand your drone’s potential with GPS-free navigation across urban, rural, and the most remote terrains, unlocking missions previously impossible.

Deserts

Navigate vast, open landscapes. Theseus' Micro VPS has been tested in harsh arid environments to ensure reliable operation even in feature sparse settings.

Forests

Operate effectively in dense, canopy-covered territories. We can perform map matching even if foliage obscures view of the ground.

Urban

The Micro VPS performs exceptionally well over urban environments, regardless of multi-pathing, jamming or alterations in the skyline compared to satellite maps.

All Season

Perform reliably in any weather, from scorching heat to freezing cold, ensuring mission success year-round.

Testimonials

Lt. COL

USAF

In the considered opinion of [our] AltPNT experts, Theseus offers a disproportionate value to the DoD in terms of its large potential and small investment request. Specifically, AltPNT has notoriously required robust processing enclaves and has a limited operational context due to SWAP considerations on fielded platforms. In that context, Theseus has demonstrated performance that rivals other technologies, but in a low-SWAP environment and with minimal processing requirements.

Capt.

USSOCOM

Having tested the Theseus’ VizNav system for a week, I am convinced that their technology presents the best solution for a current, and ever expanding, urgent operational need. Their system’s form factor and ease of integration allows for missions that are impossible otherwise.
