Fixed Solution, Wrong Coordinates? Understanding VRS and Solving Common CORS Problems
If you've been doing RTK surveying for a while, you've probably run into this before: your CORS account hasn't expired and your network is fine, but you just can't get a fixed solution; or everything worked perfectly yesterday, but today when you power on, your coordinates are off by over 10 centimeters; or you're sure you've set the correct coordinate system, but the points you're measuring are still wrong. Behind all these "mysterious" problems, there's actually a clear logic to follow. This article explains the three most common CORS problems: can't connect, cannot get fixed, and fixed but wrong coordinates, along with a practical troubleshooting workflow for each:can't connect, cannot get fixed, or gets fixed but coordinates are wrong, how to troubleshoot them step by step, and what tools can save you time and effort.

The World's First PPP UAV LiDAR | How Tersus TAP is Revolutionizing Airborne LiDAR Mapping
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.

Precision Positioning: Seamless Conversion from TAP to Local Coordinates
The Earth's surface is not static, constantly shifting due to plate tectonics and crustal deformation. This continuous motion necessitates the use of dynamic global reference frames, such as the International Terrestrial Reference Frame (ITRF).
