Discover new Drotek DP0601 featuring U-blox F9 high precision RTK GNSS module. This multi-band GNSS receiver delivers centimeter level accuracy in seconds.

Experimenting with high-precision GNSS-modules (u-blox ZED-F9P) - Part 2 (part 1: https://youtu.be/3b9ipsEoL9s )

This system consists of 3 modules, one working as a base and other 2 as rovers. Position of the two rovers is used to calculate the position of the "stylus tip". Communication with the devices and logging of the data is done with application running on a laptop the ZED-F9P-modules are connected to using USB. Some of the post-processing (creating point clouds and "movie script" for Processing) was also done using the same application. CGI-videos on the upper right and lower left were created using Processing. Meshes (convex hulls) for different parts were created using MeshLab.
