The S1’s Hardware is the Canvas
The Algorithm is the Art.

The Tersus S1 is built for organizations that need reliable SLAM technology they can trust, everywhere, every day, and across every team. Designed to deliver consistent, repeatable results in real-world conditions, the S1 empowers more people to capture high-quality 3D data without slowing down projects or relying solely on specialized crews.

At its core the S1 has a robust and refined SLAM algorithm focused on stability, residual control, and clean geometry, even in complex or visually challenging environments. The AI-driven RTK-SLAM Algorithm fuses LiDAR, vision, and GNSS data to produce photorealistic, well-aligned point clouds that support everything from rapid site documentation to advanced visualization and digital twin workflows.

Precision 3D Capture in the Palm of Your Hand

By reducing rework, and repeat site visits, the S1 helps teams move faster with greater confidence, turning 3D capture into a practical, everyday tool, all in the palm of your hand.

Intelligent Algorithms, Reliable Results

Tersus S1 sets itself apart from other manufacturers by using a fully proprietary, AI-powered SLAM engine, providing clean and precise data where open-source solutions fall short.

Density and Smoothing

The algorithms are tuned to preserve small features while managing noise, while not chasing cosmetic smoothness at the cost of true precision.

3D Gaussian Splatting (3DGS)

Equipped with dual 48 MP cameras, the MVP S1 captures stunning textures. Supported by 3D Gaussian Splatting (3DGS) technology, it generates not just point clouds, but photorealistic 3D models for immersive visualization.

Moving Object Filtering

The S1’s AI-powered algorithm automatically identifies and filters out moving vehicles, pedestrians, and other transient objects, producing a clean, static representation of urban environments for accurate mapping and analysis.

Consistency Across Every Step

The Tersus S1 is designed to maintain stable SLAM performance across long paths and mixed indoor/outdoor environments. Its AI-powered RTK SLAM and multi-sensor fusion help reduce drift and preserve alignment through transitions such as buildings to open areas, corridors to stairwells, and extended linear routes. Seamless resume scanning allows capture to pause and continue without breaking data continuity, supporting efficient mapping of large or complex sites with consistent, reliable results.

Results in less rework

Powered by advanced onboard algorithms, the Tersus S1 delivers faster convergence, stable RTK performance, and reliable positioning even in challenging environments. The result is fewer return visits to the job site, less rework due to questionable data, and a smoother field-to-deliverable workflow — helping crews stay productive, reduce downtime, and complete projects with greater confidence the first time.

Better Data. Less Time.
