      Galileo HAS is supported from firmware version 6.28. Galileo HAS has reached service level 1, which means “reduced coverage and performance with respect to the Full Service”. For example, the phase biases are still missing in the correction stream. Currently, Trimble cannot guarantee the convergence time specification at least until phase biases are provided.

3 Depends on SBAS system performance.

4 Accuracy and reliability may be subject to anomalies such as multipath, obstructions, satellite geometry, interference and atmospheric conditions. Always follow recommended survey practices.

5 Receiver accuracy and convergence time varies based on GNSS constellation health, level of multipath, and proximity to obstructions such as large trees and buildings.

6 Accuracies are dependent on GNSS satellite availability. xFill positioning without an xFill Premium subscription ends after five minutes of radio downtime. xFill Premium will continue beyond 5 minutes providing the solution has converged, with typical precisions not exceeding 3 cm horizontal, 7 cm vertical. xFill positioning without an RTX subscription ends after five minutes of radio downtime. xFill-RTX will continue beyond five minutes providing the solution has converged. xFill is not available in all regions, check with your local sales representative for more information.

7 Networked RTK PPM values are referenced to the closest physical base station.

8 RTK refers to the last reported precision before the correction source was lost and xFill started.
