Why is the P-7 Pro experiencing reduced accuracy when tested with certain apps?

Many apps in the market calculate accuracy based on a single frequency satellite system, where the accuracy values are converted from HDOP values. However, this conversion method cannot be applied to dual-frequency GNSS receivers such as the P-7 Pro and P-10 Pro. It's important to note that the coordinate readings provided by those apps are still accurate. Therefore, it is not advisable to rely solely on the accuracy readings from those apps.

To accurately test the accuracy of the P-7 Pro, please refer to the official "Columbus" instruction provided below. This instruction is also applicable to the P-10 Pro.
