Can we achieve less than 1 meter accuracy in SAM-M8Q in Open Area?

Hi,

 I am planning to use SAM-M8Q for construction worker tracking application. So i purchased EVK SAM-M8Q for evaluation.  I tested under full Sky view and i got position with 2 to 2.5 meter difference. Can i improve the accuracy to less than 1 meter?

Also can i achieve less than 1meter accuracy in indoor or between huge buildings?

If not, what might be the correct module for my application(Wearable)?

 

Thanks,

No, the CEP numbers quote in the specification are under the most optimistic conditions.

The antenna on the SAM-M8Q will also detune in the presence of the human-body.

It might be possible to buy SAM-M8Q's capable of outputting raw-measurements and use RTKLIB (or whatever), but such parts would likely be priced with a significant premium.

For indoor you're going to need to use other methods, beaconing, wifi heat mapping, INS/DR

You should perhaps seek out consultants with actual experience in this area, or purchase solutions from companies with pre-engineered solutions. Seem to recall a German company that was tracking football players, and people with shopping carts inside a super-market.
