It is low accuracy using ZOE-M8Q and passive antenna.

Hi. I’m using ZOE-M8Q and passive antenna.

antenna name is Molex Flexible GNSS Antenna - U.FL (Adhesive).

I tested using both active antenna and passive antenna standing in one place.

and I saved gps data and draw map in gps visualizer.

you can see it on attachments.

I’m wondering if the SIV is around 10, but passive is not accurate.

Is this normal?

This is active.

These are passive.

IT depends on when/where you are, view of the sky, orbiting constellations, etc…but I’d assume it is - this page https://www.taoglas.com/typologies/ has a good description for why the passive might be showing less accurate results
