Random phantom movement jumps appear

Good morning everyone, I'm having a problem with several vehicles. The vehicle is parked all morning, but random movement jumps appear. Like the example in the attached image.

Equipment: CRX3 - GT06 Protocol

Any tips for a solution?

Typically you can filter those either with accuracy filter or max speed filter.

TKS Anton.

<entry key='filter.accuracy'>200</entry>
<entry key='filter.maxSpeed'>180</entry>

Is this configuration suitable for CRX3 and ET300 devices?

You have to look at the actual data instead of guessing.

I understand. Thank you very much.

Even adding:

<entry key='filter.accuracy'>200</entry>
<entry key='filter.maxSpeed'>180</entry>

and some test variations, there are still devices that insist on teleporting. In this example, the vehicle traveled normally today (June 15, 2026), and when it was in the garage, a position from June 8, 2026 appears (screenshot). The situation is repeating itself. If anyone can provide further guidance, I would appreciate it.

Point A was the last real communication. Point B was where it teleported to. And today the vehicle did not pass through point B. This Point B is constantly repeated in this phantom teleportation situation.

I checked the database and logs, and that position from June 8th, 2026, is not showing up today, June 15th, 2026. Any help would be greatly appreciated.

Try comand sf,off# verify it supported

Cristian, thank you for your response and the information shared.

However, from what I understand, this situation is not supported.

Regarding the problem of old positions reappearing unexpectedly, I performed a more drastic test: I completely deleted the records from the positions and events tables in the database. Approximately 20 hours have passed since this intervention, and so far the problem has not recurred.

I will continue to monitor the system's behavior and, if new occurrences arise or I obtain more relevant information, I will return to update this thread. Thank you all for your collaboration.

I performed a cleanup on the positions table, and the problem disappeared. Thanks, everyone.
