Tersus GNSS
The Operating System for Spatial Intelligence
Spatial computing has entered a new era.
Capture: From measuring discrete points to real-time 3D scanning. For the past forty years, surveyors used levels for elevation, total stations for angles and distances, and RTK receivers for coordinates—one point at a time, a few hundred points a day. Trimble, Leica, and Topcon pushed these instruments to their absolute limits. But today, the industry is crossing into the era of mobile scanning: walk-and-scan handheld devices continuously capture millions of points, generating a complete 3D world in real time. The Tersus MMS-S1 was born for this era. TightSLAM™ deeply integrates our proprietary RTK engine with SLAM within our own tech stack—not a patchwork of two third-party systems, but two capabilities powered by a single engine. Wearables (MMS-W1), drone scanning, and autonomous robot scanning—the next-generation form factors are already unfolding.
Compute: From manual data processing to AI-driven scene recognition, feature extraction, and photorealistic modeling. 3DGS (3D Gaussian Splatting) reconstructs 3D scans into photorealistic, interactive scenes with a single click. Spatial foundation models extract semantics directly from point clouds—identifying buildings, roads, pipelines, and vegetation without manual annotation. These AI-generated reality models are becoming the foundational content for XR/AR immersive experiences, digital twins, and virtual production. While the algorithm layer will continue to iterate and commoditize, the quality of spatial data fed to these algorithms depends entirely on the positioning engine used during capture. Algorithms are the application layer; the positioning engine is the infrastructure.
Command: From manual machine operation to automated agriculture and autonomous construction. In agriculture, tractors use the ISOBUS protocol to share precise locations in real time with planters, sprayers, and spreaders—shutting off nozzles in sections during turns, applying variable-rate fertilizer zone by zone, and automatically raising/lowering implements at headlands. Without centimeter-level positioning, all of ISOBUS's precision controls lose their meaning. In heavy machinery, Bedrock Robotics (founded by an ex-Waymo team, $350M funding, $1.75B valuation) is retrofitting excavators and bulldozers into fully autonomous equipment, translating CAD drawings directly into machine tasks. MOBA is already using Tersus positioning modules to drive real-time machine control on construction sites. The global construction industry accounts for 15% of GDP, and the labor shortage is irreversible. Autonomous machinery is inevitable.
Three epochal leaps, sharing one common infrastructure: a proprietary positioning engine.
Most companies only build one layer. Trimble and Leica do not export their positioning capabilities. XGRIDS develops 3DGS algorithms but doesn't build scanning hardware. Bedrock focuses on autonomous construction but relies on third-party GPS modules.
Tersus is one of the very few companies that owns all three layers. We design our own GNSS chips, develop our own RTK positioning engine (one of only about six globally), operate our own global correction network (16,000+ reference stations, 70+ countries, 1.5cm accuracy), manufacture our own mobile mapping systems and receivers, and export our positioning engine to agricultural machinery, construction equipment, and autonomous robots. From antenna to chip, to engine, to correction service, to terminal, to machine control—not a single link relies on third parties.
The upper-layer algorithms will commoditize, and downstream hardware form factors will evolve. But this middle-layer engine—owned by only about six companies worldwide—is the unavoidable core.
