GNSS Tolerance Settings (Reference)

SVs Mask

The SVs Mask setting is used to establish the minimum number of satellites that are necessary to produce a solution with a valid position. The SVs must also pass the elevation mask test to be included in this number for the calculation of the rover position.

PDOP Mask

The PDOP mask is used to control the acceptable geometry of the satellites used to compute the RTK position. If the PDOP value exceeds this number, the user will not be eligible to collect an RTK position.

Elevation Mask

The Elevation Mask is used to determine which satellites to use in computing the differential corrections to broadcast to the rover(s). Satellites below this value will not be used in the solution. Elevation mask angles are typically equal or less than the elevation mask set for the rover system.
