A small team.
Tersus GNSS Inc. is founded by a team of engineers in Shanghai with US$3M investment and a mission to build a proprietary RTK chip, joining a select group of only six companies globally with their own ASIC.
About Tersus
A vision
becoming reality.
Tersus GNSS has spent a decade making precise positioning accessible to everyone. We believe that centimeter precision in the hands of people and machines allows them to work more efficiently and build better knowledge of our world. This is how we got here, and where we’re going next.
Origin
Tersus GNSS started in 2014 from a small office in Shanghai with the idea that survey-grade GNSS, the technology that lets you find any point on the earth with centimetre accuracy, should not cost as much as a car.
Our experience building enterprise networking and semiconductors for the consumer market, combined with economics of scale and improvements in sensor performance, brought survey-grade GNSS within reach. For over a decade, geodesists and surveyors have used our products to measure points with rigurous accuracy anywhere on Earth. Today, we push the boundaries of what’s possible.
Capture from single points with the highest accuracy to 3D scenes with millions of points and photorealistic reconstructions of reality. For the massive amounts of spatial data, we build powerful Compute, efficient algorithms and semantic architectures designed specifically for each industry and application. These are the foundation models that enable the next generation of engineers to Command machine automation and robotics in farms, construction sites, mines, and the rest of the physical world. That’s why we build.
A decade, in order.
The milestones that actually mattered.

2015First OEM boards.
The earliest BX-series multi-GNSS RTK OEM boards leave the factory. Hand-soldered prototypes transform into production units for early adopters.
2017Berlin, Melbourne, San Diego
Tersus GNSS debuts its products at INTERGEO in Berlin, and expands its global presence with offices in Melbourne, Australia and San Diego, USA, strengthening its commitment to serving customers worldwide.

Reality Capture.
GNSS + IMU + vision sensor fusion in the Oscar Trek extends the capabilities of traditional GNSS positioning. Reality Capture becomes a reality.
- 2025
The vision comes together.
An advanced positioning engine on propietary GNSS chips. The integration of TightSLAM in the GNSS + IMU + vision + LiDAR sensor stack. New aerial LiDAR, handheld SLAM, auto-steering, and robotic total stations form a powerful product portfolio.
Where we are now.
Eleven years in, still a product company.
Today Tersus owns the full positioning stack: GNSS chipsets, PPP-RTK, IMU/vision algorithms, reality-capture hardware, and the GeoAI layer that turns raw data into decisions for humans and machines. One engine, two work paths, and a customer base that spreads from national mapping agencies to autonomous drone services.

Where next
The
Full Positioning Stack.
Our Melbourne office opened in 2017 and is the centre of gravity for our LEO-PNT, reality-capture, mining, and construction workflows. Australia takes positioning seriously: an active research community that created the LAMBDA method for RTK positioning, Google Maps and the SLAM algorithm, an open ecosystem with a national CORS network that sets industry standards, and customers who run our equipment in large broad-acre farms, challenging underground mines, and efficient survey crews.
We are working on advanced GeoAI products and solutions. We build in the office and work on the field, acting as the bridge between our customers and the technology that Captures, Computes and Commands the world. If you want to help us build that future, we’d like to meet you.
