Hello,

I agree with @torriem.
I find it a shame not to be interested in this product, just considering its cost and its mm annonced accuracy.
Yes, we don’t need mm accuracy, but the board seems to have some advantage that we shall consider.
I just take a look to the Ardusimple hookup guide (https://www.ardusimple.com/simplertk3b-hookup-guide/):

  • The configuration software is clearly more up to date than uCenter: you configure the board with a web interface, which clearly seems more user friendly. A good point for new user.
  • As @torriem said, the simpleRTK3B Heading look very interesting. With one board, we have a dual antenna GPS. The board connect diretly to 2 GPS antenna. And heading of dual antenna is send directly into NEMA string (simpleRTK3B Heading - What communication protocol is used? - ArduSimple).
    Remember: few years ago, when AgOpenGPS start to study dual antenna system for heading, the only cheap product available on the market was simpleRTK2B+heading solution from Ardusimple. But on this product, the heading data from dual antenna was only available via UBX protocol, a proprietary protocol from U-Blox. The choise was to not implement this proprietary protocol to AgOpenGPS to keep him independant.
    Now we have on the marked a board, still at a reasonable price, that can provide a dual antena heading data directly into NEMA strings.
    Despite its higher price, this stand alone board is clearly more easier to implement than the current solution with 2 F9P + ESP32 + PCB.
  • As dual antenna heading is directly provided with NMEA strings, we can still use the “IMU GPS fusion” fonction of AgOpenGPS. Fusing GPS dual antenna haeding and IMU: the best of the 2 worlds ? And I see that in v5 an option “Dual as IMU” was added (I admit, I don’t understand what it does ?). Perhaps this will not needed if we have GPS dual antenna heading via NMEA and IMU heading at the same times ?
  • Yes, 10hz position data seems to be enough. But some works on field can be donne at 15km/h or more. Perhaps in this case a higher position rate can improve accuracy. And if not, for the position, as we have some people who are studying WASless steering, parhaps a 50hz GPS dual antenna haeding can be hepfull (AOG without wheel angle sensor - #198 by Math) ?

Apparently, some people are trying this new board with AgOpenGPS:

I hope they will share their experience here.
