  Accuracy improvement of GNSS using multiple antennas was implemented in 2017, and we were able to obtain the desired performance. Since it is necessary to switch input signals to multiple antennas, there is an issue in terms of continuity of carrier phase tracking. The accuracy improvement was particularly effective in the situation where a strong reflected signal was received.

  From 2017 to 2019, we have developed GNSS positioning simulation software with 3D building map. With the GNSS simulation software uses a commercially available 3D map, we found that we could predict RTK performance about 80 % level compared with the real RTK performance using GNSS observation data. In the simulation, it was confirmed that simulation did not require cm level true positions for radio propagation simulation. Even several meters errors of antenna can be allowed to simulate GNSS signals to some degree.
