## Recording Radar Data

If necessary, the navigator can record radar data in real time. The ECS records:
 - video data;
 - antenna position;
 - heading;
 - position, course over ground (COG), speed over ground (SOG);
 - AIS.

```{hint}
Recorded data can be played back using specialized software from **NEW SUNRISE CO., LTD**.
```

```{attention}
Any recordings or data provided in court may be considered evidence if accepted by the court.
