Which aspect is crucial for ensuring high accuracy in GNSS measurements?

The number of satellites in view is indeed a crucial factor for ensuring high accuracy in GNSS measurements. When a GNSS receiver has access to a larger number of satellites, it can obtain more data points for positioning calculations. This redundancy enhances the integrity of the measurements and helps to mitigate errors, such as multipath effects and atmospheric interference.

With more satellites providing signals, the receiver can perform better geometric calculations, ensuring that the position determined is more accurate. The increased satellite visibility leads to better satellite geometry, which is essential for reducing the potential impact of errors and improving the overall reliability of the positional information obtained.

While other factors, such as the type of software used for analysis or the age of the measuring equipment, can impact the accuracy of GNSS measurements, they are not as directly influential as the number of satellites in view. Adequate satellite geometry is foundational for effective and precise location determination.
