Track Player

This tool allows viewing how unit was moving and how its various parameters were changing with time. The tool can be applied to tracks only. There are four ways to get a track on the map:

In the 'Tracks' panel, request tracks of units' movements for any period of time.
In the 'Messages' panel, while viewing messages for the indicated period, the track is mapped automatically.
In the 'Reports' panel, while generating a report the track is mapped if the corresponding option ('Trip routes' or 'All messages on map') is activated in report template.
Tracks can be built directly from the 'Monitoring' panel with the 'Quick Track' button.

The most recently built track (in any panel) becomes selected in the Track Player automatically. However, you can switch tracks manually choosing them in the drop down list. A track name coincides with unit's name, and the panel where the track was built is specified in brackets (Tracks, Reports, Messages).

Player Settings

Adjust appropriate playback speed using the speed slider bar. It can vary from real time speed (1x) to acceleration by 1000 times (1000x). Regardless selected value, messages with zero speed and no movement will be played at maximum velocity. If you change playback speed while playing a track, new value will be applied after you press 'Pause' and then 'Play' again.

:!: Note.
Playback speed is a rather conventional thing. Playback performance depends on type of browser used, computer processing power, number of messages in the track, and time intervals between messages. It is likely that the track will be played more slowly than you expect because, in any case, all messages will be played even if it takes more time.

The map can be moved manually or automatically. This setting is adjusted with the switch button . If it is disabled, the map can be moved only manually. If it is active, the map is moved automatically in the following cases:

along with the unit, while playing a track;
when locating initial and final position in the track with special buttons;
when moving along the track point-by-point manually;
when navigating the track by clicking on different places of the timeline;
when choosing a new track in the drop down list (the map is moved to the first point of the track).

If the device used is able to send pictures, they can be displayed, too. This option can be disabled though — use the switch button .

Playback

To start playing the track, press the 'Play' button . At this, it transforms to the 'Pause' button, which can be used to stop playback. If after a pause playback is started again, it continues from the place it has been stopped the previous time. There is a similar button in the Tracks panel, against each track on the list. When the playback is completed the unit stays in the point of its last location, and the button changes from 'Pause' to 'Play'. If you click this button once again a time scale will be set to zero, and a track will be played from the very beginning.

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. A unit being played is easily distinguished from the real unit by the color of its name — purple for playable units, red for real units. While playback is performed, the real unit temporarily disappears from the map.

While playing, address and speed of each point are displayed above the timeline. Below the timeline, you can track also changing values of parameters and sensors (visible sensors only). Expand two below sections to see their full contents. There can be a great number of parameters and sensors and you may want to single out those you want to track during playback. Double-click on necessary items to move them to the main section of the player (right below the timeline). Then you can collapse sections with all parameters and sensors.

As a track is played, all data in these sections is refreshed dynamically according to message being played at the moment. If there are images in messages, they popup in corresponding places, too.

Track playback can be invoked from any message. Navigate throughout the track by clicking on any place of the timeline or track itself. Besides, you can use the buttons:

— go to first point (accompanied by the marker on the map),
— go to last point (accompanied by the marker on the map),
— move to next point of the track,
— move to previous point of the track.
