# System Monitor

The System Monitor window displays various system parameters relating to the rover and its attached sensors. The types of parameters monitored are Pose (latitude/longitude, roll/pitch/yaw, etc.), GNSS/INS (PosStatus, UncertaintyP, CorrAge, etc.), and Statistics (Packets, Points, etc.)

{% hint style="info" %}
The General section will only appear when connected to the system in real time, not when working offline during post processing.

{% hint style="info" %}
The E, N, U coordinate system under Pose isn't as per your normal, XYZ. It is defined as E as right, N as forward and U as up. It is relative to the initial takeoff location of the rover mapping system.

There are numerous statistics displayed in the System Monitor window:

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-6.phoenixlidar.com/spatialexplorer/acquisition/user-interface/system-monitor.md?ask=<question>
```

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.
