Help please ?
Set-Up is Raspberry Pi 3 with Venus OS publishing to vrm site and there is a USB GPS plugged into the Raspberry Pi 3.
This is in a stationary vehicle. Why do I see a Speed published on the VRM portal ?
Thanks in Advance

The speed is calculated from the positions. Normally every second, if the position jumps are big, this will give you a speed... even when you are not moving.
It could be that your antenna does not have a full clear sight to the sky. Or maybe interference.
Some model GPS units average the speed over the last 5 seconds..
Try to move the antenna a bit.

Could be an overly sensitive sensor? I also have a Pi and a USB GPS and mine shows zero, but oddly enough it isn't displaying altitude:
Out of interest what USB GPS units are we using? I am just setting up an Pi 2 with the Venus setup, all working well, and wanting to add GPS now.
@nebulight what GPS model is it ?
I have the MR-350PS4 SiRF Star IV. It shows up on the GUI of the GX, but not in VRM:
I think maybe the VRM is getting the Altitude from the Location info when you set Location and not getting that info as GPS data ?- I set that as the Vehicle is stationary and parked up in same spot for much of the time or it is say a Home Location
