Getting RTK cm position accuracy using simpleRTK2B+heading kit
vfseng asked 3 years ago
I got ardusimple simpleRTK2B+heading kit. It is preconfigured as a moving base (simpleRTK2Blite) along with the rover (simpleRTK2B). It provides the heading information and uncorrected position (~1.5m accuracy). However, I don’t know how to get RTK cm accuracy with this kit. I assume that the moving base need to get RTK corrections from a NTRIP provider but the only port I see on the simpleRTK2Blite moving base is the Pixhawk connector which connects only to an Ardupilot. Is there a way that I can connect the simpleRTK2Blite to computer for example to get RTK corrections via internet?
Thanks!

You’d need to get an XBee WiFi or BlueTooth so you can connect to an NTRIP server or computer.
The Lite board doesn’t provide much in the way of connectivity. The XBee header should expose the UART2, so you could wire something directly with that.
I stacked the simpleRTK2B boards, which provided more connectivity options. That require bending of pins, and wiring connections between them.

If the Pixhawk/ArduPilot don’t push in the data over their radio links, you’ll need your own radio on the stack.

Hi Ramy,
You can connect to the XBEE+POWER USB. This one give you access to the simpleRTK2Blite. You can send corrections through there.

Many thanks Ardusimple. Is the communication to the simpleRTK2Blite through the XBEE+POWER USB port direct (plug and play) or I need some setup/configuration/settings change for that? Also, can the u-center software access the simpleRTK2Blite directly through this connection (to send correction data) ?
Thanks to point me to any documentation/manual that can give more details about accessing the simpleRTK2Blite through the XBEE+POWER USB port.
Thanks again!

We use FTDI converter in POWER+XBEE connector, so you only need to have the FTDI VCP driver, and configure the com port from u-center at 115’200bps. You can now send correction data from u-center and communicate with the lite. All documentation is on our simpleRTK2B+heading hookup guide.
