It is possible to view how unit was moving and how its various parameters were changing with time. This tool is applied to tracks only. There three ways to get a track on the map:

1. In the map mode, open the Tracks panel and request tracks of unit movement for the indicated period.
   
   
2. In the messages mode, while viewing messages for the indicated period, the track is mapped automatically.
   
   
3. In the reports mode, while generating a report the track is mapped if the corresponding option ('Trip routes' or 'All messages on map') is selected in report template.
   
   
4. Tracks can be built directly from the monitoring panel with the Fast Track Building button.

A track is chosen in the dropdown list. Track names coincides with unit name, in brackets it is specified in which mode the track was built (monitoring, reports, messages). When you choose one or another track, the map moves to it.

After selecting a track, choose the most appropriate speed for its playback: real time speed, 10 or 30 seconds per second, 1, 5, 10, 30 or 60 minutes per second.

By default, messages with zero speed are skipped. It means, only intervals of movement are played. However, some devices do not send speed, and to play their track, it is necessary to disable the check box Ignore the messages with zero speed.

To start playing the track, press the Play button. At this, it transforms to the Pause button, which can be used to stop the playback. If after a pause the playback is started again, it continues from the point it stopped the previous time.

As messages are being played, the selected unit is moving over the map. It can be represented by its icon or movement state signs. It is also convenient to use rotating icons - see Unit Presentation on Map. When a unit is played, its real position disappears from the map. To distinguish these two modes to display a unit, its name in track player is violet (in contrast to usual red name).

If playback speed is not very high, the map is centered on each message. However, you can adjust a handy zoom and scale for the map and disable the flag Move map while playing. Then the map will not jump automatically while playing.

Track playback can be invoked from any message. Navigate throughout the track by clicking on any place of the timeline. If just hovering the timeline, time is indicated above. To navigate through a track, you can also use arrow-shaped buttons - to move to the next/previous point of the track.

Additional information is available below, in 4 sections (mark the appropriate checkboxes to expand necessary sections):

1. Information: message number of the whole number of messages, message time, speed, and location.
   
   
2. Parameters: available parameters and their values.
   
   
3. Sensors: available sensors and their values.
   
   
4. Pictures: if the device used is able to send pictures, they are displayed.

As a track is played, all data in these sections is refreshed dynamically according to message being played at the moment.

Note:
Sometimes Track Player can occupy much room of the screen, and not enough space will remain for the map. To help this, you can hide two things:

• Track Player itself - use the button in the top right-hand corner of the tool dialog.
• Work Area - use the button at the bottom panel.
