I don't think there are any more or less accurate units. All GPS modules have similar accuracy assuming there is nothing wrong with antenna.
Can this be considered normal in the image?
What would be a good way to get around this problem?
Remembering that it would also be used for theft monitoring.
It is normal GPS behaviour. To avoid it, you can enable filtering. It has been discussed many times on the forum and GitHub.
Thanks, I'll search
I actually think that the trackers from Queclink (like your GL300) are among the most accurate ones, because they support both GPS and GLONASS. (Most Chinese trackers only support GPS.) If I'm not mistaken, you can configure the GL300 to stop reporting after sitting idle (no movement) for a while and only when it detects motion again, it will resume reporting. Shouldn't that solve your problem as well? (It also saves a lot of data & battery.)
Hey, we're currently trying to use the gl300 to track positions, SOS and battery for cars and sales machines.
Which GPS is more accurate and has features similar to the gl300?
