# 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 Speed option can be accessed by left-clicking and holding the “play” radio button located in the left-hand side of the Playback menu. This option allows controlling the playback speed of the loaded trajectory.

| Speed | Playback            |
| ----- | ------------------- |
| 0.0   | As fast as possible |
| 1.0   | Realtime            |
| > 1.0 | Slower motion       |

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.

The Step option allows you to forward the scan to the first instance of either GNSS, LiDAR, or Camera data. To access the Step option menu, left long-click the “play” radio button, highlight “Step until...” and select your option.
