Ntrip corrections Over Xbee radio

Q&A forumCategory: QuestionsNtrip corrections Over Xbee radio
leonciosl asked 2 years ago

Lasts days I have been proving ardusimple working with Ntrip corrections by android app, and it works really well!
However there are regions (rural zones, usually ) where 3G does not arrive with quality enough to work so.
I see , you are going to sell Xbee radios in February, have you thought the possibility of sending ntrip corrections over Xbee radio from one place (with 3G good enough ) to another ? 
I suppose you must implement an usb connector to your radio system , or even better … an usb to power it and a Bluetooth module to read ntrip messages from Android. (With only usb connection, I suppose we were forced to use a mini laptop or a window tablet ).
As far as I see, it would be a great advantage, not only for ardusimple users but for a lote of surveyers either !!  Because It would give you the opportunity to work in real global coordinates with cm accuracy.
 
Thanks for this project!! (again 🙂

Hi leonciosl,
Our base-rover configuration with the MR or LR kits provide RTCM corrections without any need of 3G connectivity/smartphone/computer.

Yes … it does , but it does not work in global coordinates, it works in an own (local) reference system , what is (in my opinion) a disadvantage .
Could the MR/LR kit send Ntrip corrections from mobile app with the necessary configuration? ( no information from Gnss base is required ) .
Could I connect a Xbee radio in UART1 and your Xbee bluetooth in UART 2 ?
Thanks

Hi leonciosl,

(Leonciosl) Could the MR/LR kit send Ntrip corrections from mobile app with the necessary configuration?
(AS) You can connect the XBee of the base directly to a PC and use the board only as a radio link to the rover. And you can send corrections over the air.
(Leonciosl) Could I connect a Xbee radio in UART1 and your Xbee bluetooth in UART 2 ?
(AS) Yes but it’s not plug-and-play, you can connect Bluetooth to UART2 https://www.ardusimple.com/product/bluetooth-module/ and you will have to manually wire an XBEE to UART1.
