# Navigation System Configuration This section covers topics related to the navigation system. The navigation system records raw GNSS and IMU data for use in post processing, as well as provides real-time estimates of it's geographic position, attitude (roll, pitch, yaw), and the quality associated with those estimates. The real-time pose and attitude quality estimates do not necessarily determine the quality of results that can be achieved during post processing, however some navigation system issues cannot be resolved through post processing, so it's important to understand how to correctly configure the navigation system prior to acquiring data. The real-time navigation system mirrors post processing software ([NavLab](/spatialexplorer-8-and-9/user-interface/toolbars/workflow/navlab-embedded.md) and [InertialExplorer](/3rd-party-software-documentation/inertialexplorer-desktop-8.70-8.90-processing.md)) in many ways, and the similarities and differences are discussed. --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.phoenixlidar.com/data-acquisition-and-uav-piloting/navigation-and-alignment-techniques.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
