# Playback Menu

The Playback menu allows you to playback the data files generated by rover. 

* Once the data is loaded, you can control the playback (Rewind, Step, Play) or select a specific time.
* Displayed below the playback options is the period during which Sensor data was captured. 
* The TOW (time of week) displayed is the time at which the trajectory (.nav, SBET.OUT, etc.) file began recording.

| Playback visualization | Description     |
| ---------------------- | --------------- |
| Red bar                | LiDAR data      |
| Green bar              | Camera data     |
| Purple bar             | Trajectory data |

* The GoTo option (represented by the image of a stopwatch) allows you to view the data at a specific point in various time formats.
* The desired time can be specified in many time systems.
* Conversion of leap seconds is done automatically.
