5.3.10 GNSS Environment
Figure 88: MOTION Settings Wizard - GNSS Selection
Specify what environment you will be operating in to determine what GNSS reliance to use.
Open Water Survey - use this option when high GNSS availability is expected, and to prioritize
GNSS-determined positions. This is the default setup.
Inland Waterway Survey - use this option when GNSS availability may not be optimum, for
example near trees and encountering occasional narrow bridges.
Bridge Inspection - use this option when poor GNSS coverage will be expected, for example
with numerous extended cut-offs or very poor visibility of the sky. In this setup, the IMU
measurements will mostly take precedence in case of discrepancy with GNSS-determined
position.
