accuracy

The locational accuracy of CNPS is superior to that of
European companies.

In the fixed test, the competitor's location measurement is somewhat spread around from the original
position value as shown on the left. In the same test, we can see that the devices of CNPS are focused on one point.

WHY CMPRO

RTK is a technology developed to complement GPS,
which causes several meters of error due to signal disturbance
and delay caused by ionospheric interference.

In the case of GPS control at the bottom of the figure when using one-way GPS, the container position is not measured accurately, so it is jagged when viewed in the program. However, if you look at the RTK, you can see that it is not different from the actual container location.
