NTRIP Base ESP32 ESPrtk F9P TOPCON Ardusimple RTK – Simon Barlow


Hello ESPrtk User and Happy new year 2022 !🎄 ❄️ 🎅🦌☃

This is the ESPrtk NTRIP Base project for Simon Barlow’s TOPCON tractor.

He uses F9P Ardusimple as RTK Base receiver and uses W5500 Ethernet + ESP32 running ESPrtk NTRIP as RTCM data bridge.

He also applies RTCM 1004/1012/1008 injection to be able to use F9P for his TOPCON tractor but only get RTK FIX in 5 minutes.

Next step, he try with 1005(1),1007 (1),1032(1)1077(1)1087(1) on PX1122R and got stable RTK FIX on TOPCON !

Below are some photos he emailed us of the ESPrtk Ardusimple DIY board and setup.
