# Setting DVL Mounting Rotation Offsets These parameters set the orientation assumed by the Tracker 650 when it converts its velocity calculations into the coordinate frame used by the vehicle. See [here](/c/tracker-650/communicating-with-the-tracker-650/commands-accepted-by-the-tracker-650/set-sensor-orientation.md) and [here ](/c/tracker-650/mounting-the-tracker-650/thruster-deck-mount-example.md)and [here ](/c/tracker-650/coordinate-systems.md)for discussion of how to determine these values. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
