Centimeter accuracy compatible GPS with Traccar

Hi everyone,

I provide services for the agro industry in Chile. We are using Teltonika model FMB130 GPS hardware and it has less than 3 meter accuracy. We need less than 50 cm accuracy.

Can anyone recommend a centimeter GPS hardware compatible with Traccar?

Thanks a lot

I don't think GPS satellites support that accuracy.

Okay, thanks a lot for the answer, you might be right!

In that case, do you have experience with any particular accurate device? Or wich device is the most accurate?

Thanks a lot

I don't really have much experience with hardware, but if you want higher accuracy look for devices that support external antenna. Get a good antenna, place it outside of the vehicle and that should give you the best possible accuracy.

Great! Thanks, for your support it make sense.

If you need high accuracy you always need a second signal. In Europe it calls correction Signal.
We have about 10 Providers for this.
They go for 1cm accuracy but also for lot money a month.
But i dont know if Chaile has something like that

Thank Marcin, If you can share me one or two providers from the list I will appreciated.

In the oder hand I will continue trying Anton idea using an external antenna.

Maybe you can translate this with google?

Hi guys, Anton was right! We use a Teltonika FMB640 with a powerful antena and we achieve less than 1 meter accuracy.

Thanks a lot and if any one need more information, please let me know in order to upload a photo with a link were you can see differences of position quality between with and without antena.
