"GNSS-stylus" with a laser distance measurement module - PoC

Experimenting with high-precision GNSS-modules (u-blox ZED-F9P) and laser distance measurement module. This is just a proof of concept-test. This system consists of a laser distance measurement module, 2 GNSS-rovers and a NTRIP-base. Position of the rovers and distance measurement from the laser distance measurement module is used to calculate the position of the "stylus tip" (in this case the laser dot) in relative (NED) coordinates to the base. Communication with the devices and logging of the data is done with application running on a laptop the modules are connected to using USB. There's not much intelligence when calculating the position of the dot, this version of the program just uses latest coordinates and distance.

The program used in the laptop is currently under developm
