@THiamu great experiment you’re doing here !
I’m currently planning to design a PCB for AOG (hes another one, see here : Project : designing an all-in-one compact PCB for AOG - what do you need?) which will include two GNSS recievers.
The PX1122R looks like a promising alternative to the ZED-F9P : cheaper, smaller and with similar performances (at least at first sight). I have a few questions about it :
- Are there GND pad under the module ? (I didn’t find a photo of it from behind). If there are none, the module can be soldered by hand more easily, which is nice.
- The heading and roll calculations are made internally, which means there is no need for an ESP32 like here ?
- How does it communicate with AOG ?( I guess UART to USB)
- Is AOG now fully compatible with a dual PX1122R setup ? If not, are there plans to make it compatible in the near future ?
- Is there a software similar to U-Center allowing to configure / monitor the modules ?
- Did you manage to build a RTK base station with NTRIP with this module ?
