Local Base without connection for FACET and drone application

GPS/GNSS Development Boards

Hello,

I would like to know if with the addition of the TCP Server/Client functionality, there is the possibility of using the RTK FACET as BASE for drone corrections by opening its own connection/port with relative mountpoint and sending them to drone.

Looking online (https://mettatec.com/online-store/uncat … urpad-app/) I see GNSS with same GPS which include this possibility it would be a great help when in the field it is not always possible to using an internet connection. All this would make the drone mapping system autonomous, and it would be very helpuful in the various process.

What I’ve done is to create an Ntrip caster on my Facet. It casts to the drone controller and sends corrections to the RTK drone.

I use the Emlid free service and the rtk2go free service.

Without internet a Base/ Rover setup collecting GCP’s and correction via OPUS or the Canadian service.

Hi mgphoto ,

thanks for the reply in the past months I’ve done the same with emlid caster but you need always internet connection.

With the possbility to open a NTRIP SERVER on the facet, like the one I think they have done on the mettatec, it would be possible also for the facet.

I have honestly never tried the PPP services you indicated, would they also be valid in Italy for processing?

Greetings Daniel.

Hello Daniel, I read through the mettatec documentation, it doesn’t mention the accuracy of the local Ntrip data. Could just be a single solution with relative accuracy to the base?

PPP I believe can be used worldwide, I think there is a European service available. I know the Australian service covers Asia.

I thought of connecting a Facet to a laptop running an Ntrip server which could send corrections to the Base Facet using the Ntrip client, I’m not sure this would work? I’m hoping someone smarter than me will chime in.

If I used a WiFi hotspot to connect all of the devices to form a local area network without internet connection, could this be possible?

Thanks

Mike

Hi mgphoto,

As you mentioned it would be usefull the LAN connection with hotspot mode, waiting for the reply from sparkfun and their help :slight_smile:

I believe this would be a very useful feature. How do we request this if it is already being requested?

Also how would this be implemented? I’m very interested.

Hello,

Yes that is the feature that would be very useful, as lke EMLID and others have done.

Greetings Daniel. :smiley: :roll:
