The World's First PPP UAV LiDAR: How Tersus TAP is Revolutionizing Airborne LiDAR Mapping
Tersus GNSS, Peter Yang 13 January 2026
Introduction: The Tether of Tradition
For decades, high-precision aerial surveying has been tethered to the ground. To achieve the centimeter-level accuracy required for professional deliverables, surveyors have had two choices: set up a local RTK base station or connect to a Network RTK (CORS) service.
Both come with significant baggage. Base stations require extra gear, setup time, and precise known coordinates. CORS relies on cellular networks, which vanish the moment you head into remote mountains, deserts, or offshore environments. But what if you could cut the tether?
Introducing the World’s First PPP UAV LiDAR
At Tersus GNSS, we are thrilled to announce a game-changing upgrade to our MetaVerse Painter 100 (MVP100) Mobile Mapping System. By integrating our proprietary Tersus Advanced Positioning (TAP) technology, the MVP100 has become the world's first UAV LiDAR scanner capable of Pure PPP (Precise Point Positioning) processing.
This means you can now achieve survey-grade accuracy directly from satellite corrections—no base station, no cellular network, and no CORS subscription required.
How It Works: RTK from Satellite
TAP is a satellite-based augmentation service that broadcasts real-time corrections (ephemeris and clock errors) globally.
The workflow with the MVP100 is revolutionized:
1. Power On: Turn on the MVP100 in the field.
2. Converge: Wait just 3 minutes for the TAP service to converge and achieve a "Fixed" solution.
3. Scan: Launch your drone and capture data.
4. Process: Generate accurate point clouds without needing to import base station files.
Solving Real-World Pain Points
This technology isn't just cool; it's a critical problem solver for surveyors facing real-world challenges:
1. The "Remote" Reality: Surveying mines in the Andes? Mapping islands in the Pacific? Monitoring pipelines in the desert? In these "communication dead zones," CORS is impossible, and hauling base station gear is a logistical nightmare. MVP100 + TAP works anywhere you have a view of the sky.
2. The Ultimate Insurance Policy: Even in urban areas, things go wrong. Batteries die, base stations get knocked over, or someone forgets to record the static data. With TAP enabled, your MVP100 is always collecting high-precision position data independently. It turns a potential "re-fly" disaster into a successful day at the office.
3.Efficiency Boost: Eliminating the base station setup saves 30-60 minutes per project. On multi-site days, this efficiency compounds, allowing you to map more acres in less time.
Accuracy You Can Trust
Freedom doesn't mean sacrificing precision. The MVP100 with TAP achieves:
< 1.5 cm Horizontal Accuracy
< 3 cm Vertical Accuracy
This meets the stringent requirements for topography, construction, and infrastructure inspection, all while carrying a payload of just 1.45 kg.
Conclusion
The future of mapping is untethered. With the MVP100 and TAP, Tersus GNSS is giving surveyors the freedom to map the world's most challenging environments with confidence.
