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 This documentation is published with GitBook.
