【Process drone data】Why do I get low PPK fix rate?

Question

Why do I get low PPK fix rate?

Answer/Cause

A low PPK Fix rate may affect the accuracy of the processed data (*not only point cloud). If the red X mark is displayed on the drone flight path as follow, drone photo was not processed properly.

The following measures are effective.

1. Make sure Smart Construction Edge have good sky visibility when (away from any obrtract)
2. Make sure you start recording base log before and finish recording after drone flight
